When Rainfall Causes Problems

If you were waiting for some rain before planting to control erosion wait no more. That last storm brought plenty of the wet stuff and the next round is hopefully not far off. You?ve gotten a reminder of those areas that need stabilization during the rainy season.

Fall is the perfect time to start planning and planting. The nights are cooler, the days shorter and the soil still warm. Everything that a new plant needs to get a good start.

Using the right plants on hillsides can help slow, spread runoff and prevent soil erosion. Often they need to adapt to shallow, poor soil and cope with less than ideal conditions all while putting down dense, strong roots. Mulch also protects soil from direct rain impact and slows runoff across bare soils. This is important while new plants are growing in. Covering the steepest slopes with jute netting through which plants may be installed is an added precaution.

What plants are good for controlling erosion in our area? When choosing plants to cover a bank for erosion control, assess the conditions of the area you want to plant. Is it in the sun or shade? Is it a naturally moist area or dry? Do you intend to water it or go with our natural cycle of wet in the winter and dry in the summer? Matching the plant to the site conditions will ensure success. California natives are well suited to this job.

If the area you need to stabilize is large and mostly shade, consider ribes viburnifolium or Evergreen Currant. Like mahonia repens or Creeping Mahonia it needs no irrigation when established. Another native, the Common or Creeping Snowberry can also hold the soil on steep banks, spreading by underground stems that stabilize the soil.

A bank in the sun would contain a different plant palette. Common native shrubs for sun include ceanothus groundcover types such as ?Centennial?, ?Anchor Bay? and maritimus that are not attractive to deer like the larger leaved varieties. Manzanita are also excellent at controlling erosion.

Some other good California native shrubs for erosion control are Western redbud, mountain mahogany, Western mock orange, lemonade berry, toyon, bush poppy, matilija poppy. spicebush, pink flowering currant and Western elderberry.

Smaller natives that put down deep roots are yarrow, coast aster, California fuchsia, wild grape, mimulus, buckwheat, wild rose, sage, deer and needle grass, Pacific Coast iris, penstemon, artemisia and salvia.

Remember when setting plants on a steep slope to arrange them in staggered

rows. Make an individual terrace for each plant and create a basin or low spot behind each one ( not around the stem ) to catch water. Set the crowns of the plants high so they won’t become saturated and rot after watering and make sure mulch does not build up around the stem.

These suggestions are just a few of the plants that control erosion. Every area is different and every situation unique.

Stars of the Fall Garden

More and more of us are embracing the concept of gardening with a sense of place. To garden where you live means accepting that your garden in California is naturally more subdued by fall. Plants that bring color to the garden at this time of year are invaluable. A successful garden is a feeling.

The fall bloomers and ornamental grasses are at their peak right now and thanks to our recent rainfall they are getting a big drink. Many birds are loading up on carbohydrates and fats to provide fuel for their migration. Others will stick around and want to be in the best possible condition for the winter season. In addition to seeds, nuts and acorns, flowers are important in their diets,

leonotis_leonuris
Lion’s Tail

With Halloween almost upon us orange blooming plants like Lion?s Tail look perfect in the autumn garden and gets the attention of birds, bees and butterflies. The scientific name leonotis leonurus translates from the Greek words meaning lion and ear in reference to the resemblance of the flower to a lion?s ear but this perennial shrub has long been called Lion?s Tail in California. A member of the mint family it starts blooming in very early summer and continues through fall. Having very low water needs and hardy down to 20 degrees it?s perfect for a drought tolerant garden.

California fuchsia is also at the height of its blooming season. Starting in the summer and flowering through fall this California native will be covered with orange or scarlet-orange flowers that attract hummingbirds like crazy. A great plant along the path or draping over a rock wall this perennial thrives in areas that might fry other plants. Also known as Epilobium canan or Zauschneria it is in the evening primrose family and native to dry slopes and chaparral especially in California.

bulbine
Orange Stalked Bulbine

Another good choice for your drought tolerant garden is the long blooming Hallmark bulbine. The Orange Stalked bulbine is a succulent you?ve got to try. Starting in late spring and continuing through fall and often into winter this one foot tall groundcover spreads to four or five feet wide. The orange star-like flowers with frilly yellow stamens form atop long stalks that rise above the foliage. Remove spent flower stalks to encourage reblooming.

mimulus
Mimulus Jelly Bean Gold

What?s a fall garden without an orange or gold hued mimulus to feed the hummingbirds? Mine haven?t stopped blooming since early summer. Deer resistant and drought tolerant Sticky Monkey flower get the sticky part of their common name from their leaves which are covered with a resinous oil discouraging the larvae of the checkerspot butterfly from dining too greedily.

Orange and blue are opposite on the color wheel so they look fabulous together. Enter the salvias with their mostly blue and purple flowers. From California natives such as salvia clevelandii to Mexican bush sage to Autumn sage there are thousands of varieties on the market. All are deer resistant, gopher resistant, drought tolerant and hummingbird magnets.

California Natives for Containers

My ambitious plans to augment this garden here in Bonny Doon with California natives and colorful plants to attract birds and wildlife is not turning out exactly as I?d pictured. I thought that I had licked my gopher problem by planting everything in baskets. Not so, now they just come up next to their plant of choice at night and eat whole thing from the top, dragging the rest down into their neat little hole while leaving the root still snug in its basket. Hopefully, some will regrow from the roots.

rhododendron_occidentale3
Western azalea

But I?m not giving up on planting for the birds and bees. I?ve got plans to increase my container garden collection. Gardening in containers is easy. I can control the soil, water and light and the gophers can?t undermine my efforts. There are a lot of California native plants that do well in containers and I?m going to place them where both the birds and I can enjoy them.

For some of my largest containers I?ll choose from natives like Western Azalea, Deer Grass, Chaparral Pea or Giant Chain Fern. Any of the taller growing ceanothus and manzanita would look great too by themselves or combined with smaller growing plants.

mimulus_JellyBean_gold
Mimulus ‘Jelly Bean Gold’

For small to medium containers I can use Conejo Buckwheat, Hummingbird Mint, Penstemon Heterophyllos, Mimulus, Woolly Blue Curls or Coastal Daisy, These combine well with colorful Lewisia, Dog Violets or Wild Strawberry.

I might combine a madrone with a Canyon Gray Coastal Sagebrush – Artemisia californica – which grows about a foot high and will trail over the side of the container adding beautiful gray color to contrast with the rich green of the other leaves. I also like the combination of California Hazelnut, Deer Fern, Redwood Sorrel and Wild Ginger.

Some of the most dramatic containers utilize the concept of combining a thriller, some fillers and spiller or two. Not all my containers will use this formula but I seem to be drawn to those that do. Plants in nature can be quite random in the way they grow together and still be lovely. Containers need a bit more order to dazzle and direct the eye.

Thrillers act as the centerpiece of a container. They are usually big, bold and beautiful. Giant Elk Clover is one such California native that is an attention getter. Chilopsis linearis-Desert Willow is another great subject for containers as it is slow growing and beautiful in leaf and flower. Other architectural natives that will catch your eye as the centerpiece of a container are Hibiscus or Rose Mallow and Pacific Dogwood. The thriller goes in the center of the pot or if your container will be viewed from only one side it goes in the back.

Next come the fillers. They can be foliage or flowering plants but they should complement and not overwhelm your largest plant. Usually they have a mounding shape and I?ll plant several around the thriller. Good fillers include Heuchera Maxima and Western Maidenhair Fern.

The last plants I?ll add are the spillers which are small and will soften the edge of the container. Redwood Sorrel, Wild Ginger and Miner?s Lettuce are good choices. California Fuchsia would look spectacular with its red or orange flowers and grey foliage spilling down the side of my container.

The best overall soil mix for natives in containers sharp sand and horticultural pumice added to a good potting soil. Never use perlite or that puffed up pumice because it will float and look terrible. Happy Container Gardening.

Climate Smart Plants for the Garden

All this talk about ?drought tolerant? plants or ?water smart? plants is misleading in some ways. What really matters for the success of a plant in your garden is that they are climate smart. You can call the new California garden climate tolerant or climate adapted but it all comes down to the same thing. The plants you choose to grow in your garden should be able to naturally tolerate periods of lower than average water. This doesn?t mean no water during extremely long dry periods. No plant can live without water.

I have two books that I look to for plant ideas when called upon to design a garden in our area. This first was published by East Bay MUD in 2004 and is called ?Plants and Landscapes for Summer-Dry Climates?. The other book I refer to regularly for ideas and information is ?California Native Plants for the Garden?. Both are invaluable in these times of water conservation. One of the best tips each of them offer is to garden where you live.

All of us live in a summer-dry climate. Summer-dry gardens are naturally dry for long periods. Knowing which type of plant community you live in can make the difference between success and failure in your garden. Choose the right plant for the right place whether it?s a California native from an area with similar soil and exposure or a plant from another Mediterranean-like climate with growing conditions like yours.

Plant communities have evolved over time with geologic changes in climate, topography and soils. We have several district areas here- mixed evergreen forest, redwood forest, chaparral and sandhills.

If you live in a mixed evergreen forest you garden with trees like coast live oak, tan oak, madrone, bay and buckeye. Understory plants include ceanothus, coffeeberry, hazel and poison oak. Your soil contains serpentine and granite. Many other unthirsty plants like salvias, lavender, santolina, society garlic, giant feather grass, rosemary and rockrose do well here. California natives such as western mock orange (philadelphus lewisii), wild ginger and western sword ferns grow here also.

Mixed evergreen forest may also be found along canyon bottoms near streams where big leaf maple, white alder, cottonwood, and western sycamore trees grow. Most plant here grow lush in this deep soil. If you are looking to add something new to your garden here consider giant chain fern, aquilegia, dicentra, Pacific Coast iris and fuchsia-flowering gooseberry.

Chaparral areas are the hottest, driest slopes of these mountains. Dense thickets of manzanita, coyote brush, chamise, coffeeberry, ceanothus, monkey flower and sage are native here. These plants are adapted to little water and often have tiny, thick, waxy, light green or grayish leaves. Soils tend to be rocky and shallow with overlaying rock or a subsoil that is mostly clay. Plants here need to have an extensive root system that reaches widely and deeply for water. If you live here a classic combination would be the spring blooming western redbud and Julia Phelps or Dark Star ceanothus. The combination of magenta and electric blue flowers is unforgettable.

The sandhills near Quail Hollow and Bonny Doon around Martin Rd. are part of an ancient sandy sea floor that was uplifted, eroded and exposed. These sandy soils lack organic matter and nutrients and their white color magnifies the temperature of the summer sun. Unique, native plants like silverleaf manzanita and Ben Lomond wallflower live here. Buckwheat and sticky monkey flower do well here. You might also try growing Lewisia, a pretty little plant native to northern California, thrives in sand and gravel soils with good drainage. This 8″ tall hardy perennial blooms from spring to early summer with extremely showy flower clusters in colors ranging from apricot to pink, rose and bright cherry red. Mulch them with gravel or crushed stone.

Remember right plant-right place. Don?t try to force nature although most gardens do look better with some summer water. Closer to the house we expect a fuller look. Combinations I?m going to try this season include leucospermum paired with blue echium or grey-leafed westringia planted with red-flowering callistemon ?Little John?.

Adding Bright Color to the Garden

Yellow primrose

Do you ever look at the collection of cut roses at the market and think ?Which is my favorite color today?? Sometimes it?s the strawberry pink ones I?m drawn to other times i like butterscotch or deep red. It?s the same dilemma in my garden. I try to use restraint and stick to just 3 colors but who can do that, really? In early spring I love the soft pink and pure white of bleeding hearts, camellias and early rhododendrons but maybe because I?m surrounded by so much green, I?m drawn in summer to the bright jewel colors of orange, yellow and red in my garden.

clivia_miniata
Clivia miniata or Kaffir lily

I?m looking forward now to my orange clivia flower clusters that are emerging from deep within the dark green strappy leaves and will be opening soon. The color is especially vivid on a dark rainy day. I also have lots of deep golden and red primroses blooming now. I?ve enjoyed these same plants blooming repeatedly for many years in partial shade. I even get some sporadic blooms throughout the summer.

hakonechloa_macra_Aureola
Japanese Forest Grass – hakonechloa macra ‘Aureola’

Also at this time of year I get color from foliage too. My ?All Gold? Japanese forest grass and the variegated one have emerged from winter dormancy and they are some of my favorites. Besides being deer resistant the sound of the leaves rustling in the wind adds another dimension to the garden. The chartreuse leaves of heuchera ?Citronelle? – coral bells – add a colorful touch of foliage all year round. There?s a variety called ?Lemon Chiffon? and another named ?Lime Rickey? that i want to add to my collection also.

Later in the season I look to brighter flowers to brighten my garden. High on my wish list for several years is the kniphofia or red hot poker. In addition to yellow and red varieties there?s a cool dwarf one called ?Mango Popsicle? available now. This terrific drought tolerant plant attracts hummingbirds and blooms continuously from late spring into fall. Other colors in this dwarf ?Popsicle? series are banana, creamsicle, lemon, papaya, pineapple and fire glow. All would look awesome planted in a drift.

There are so many plants I want to add to my perennial garden on the terraces between the low rock walls. Some of the existing plants are California natives like salvia ?Bee?s Bliss? with some water smart South African plants such as coleonema ?Sunset Gold? and leucodendron ?Safari Sunset? and an Australian grevillea ?Coastal Gem? thrown in.

Because I wechinacea_Hot_Coralant to add more vibrant colors to this area I?m looking to some of the new?echinacea or coneflower. From deep gold to pumpkin orange to red-orange sunset colors this perennial has medium water needs once established and is deer tolerant. I?m hoping the seed heads will attract more goldfinches to my garden if I don?t deadhead but allow the flowers to remain on the stalks throughout the summer and into the fall. I can also plant more California native grasses for the goldfinches like blue and yellow-eyed grass and festuca californica.

Santolina 'Lemon Fizz'
Santolina ‘Lemon Fizz’

A plant like santolina ?Lemon Fizz? provides chartreuse mounds of fragrant foliage for year-round color. In the summertime it?s topped with bright yellow flowers. This compact evergreen plant is perfect to edging pathways, borders and in herb gardens. Plant in mass for a colorful, drought tolerant ground cover.

I have quite a few native sticky monkey flowers in orange and yellow that the

hummingbirds love. Also the reddish-orange California fuchsia adds color to my landscape later in the summer cascading over the rock wall. A lemon yellow fremontodendron or flannel bush would add some height to my slope.

Also I?ve wanted an Island Snapdragon or galvezia speciosa to add to my red-yellow-orange color scheme. This evergreen California native blooms with bright red snapdragon-like flowers in late winter through early fall. It?s a tough plant and very adaptable to many garden situations and soils. It can

even be hedged or pruned to ground level to keep the foliage fresh.

The bright colors of yellow, orange and red play well with blues and purples and are especially useful in mid-summer when the harsher light of the direct overhead sun can wash out paler hues.

Exploring Mendocino Coast Botanical Gardens

Mendocino Coast Botanical Gardens

What could be more lovely than spending Christmas Eve at a botanical garden? After a windy, stormy morning the clouds cleared and winter sun brought color to the golden heather, early blooming rhododendron and grevillea growing in the Mendocino Coast Botanical Gardens. I’ve long wanted to visit this famous garden and here was my chance. I was not disappointed at what is described as 47 acres of beauty to the sea.

The mission of the Mendocino Coast Botanical Garden is to conserve plants in harmony with the Northern California coastal ecosystem. Like your own garden this one provides interest year round. I could see the affects of the long summer drought on some of the rhododendron leaf edges but winter rains have turned every fern and blade of grass bright apple green. Mushrooms emerged from

damp earth and the Fern Canyon Creek looked more like a small river.

Dogs are welcome here at the Mendocino Coast Botanical Garden so Sherman, our Welsh springer spaniel, was overjoyed with the gardens, too. He seemed to favor the weeping Lebanon cedar and red-twig dogwood but the wild ginger was a big hit also.

It’s an easy half mile walk from the perennial garden to the spectacular vista at the ocean’s edge but with so many side gardens and side paths the journey is as long as you want. In the summer and fall the perennial garden is ablaze with blooming plants but even at this time of year there are many specimens that provide foliage color and structure.

euphorbia_lonicera-nitida
Euphorbia paired with lonicera nitida

I especially liked the combination of blue euphorbia paired with Baggeson’s Gold lonicera. This type of lonicera is not the familiar honeysuckle vine but an evergreen shrub called? box honeysuckle. It is hardy to cold and requires only moderate irrigation. Other favorite plants in this section of the garden were the blooming hellebore, pheasant tail grass, dwarf conifers, Hinoki cypress and a brilliant purple hopseed.

Pink Delight rhododendron

Further down the path, the garden’s signature plant, the rhododendron, made its appearance. Several varieties from the Himalayas including Pink Delight and the fragrant, Harry Tagg, are early bloomers and were covered with blossoms. Many tree-like rhododendrons, including the native rhododendron californicum and the Big Leaf rhododendron will put on their show in late spring.

Bergenia cordifolia
Bergenia cordifolia

Blooming also in the woodland garden large stands of bergenia cordifolia bordered the path, their bright pink flower spikes surrounded by huge round leaves. Helleborus take any amount of winter weather and the Corsican hellebore at the botanical garden were also in full bloom.

I’ve seen huge fuchsia shrubs before but never a fuchsia tree with flaky bark and a few brave fuchsia flowers growing right out of the wood. Fuchsia excorticata is the world’s largest fuchsia and in its native habitat, New Zealand, is can grow to 36 feet tall and form a trunk over a yard in diameter. The flowers are rich in nectar and visited my honey-eating birds there. The dark purple berries, known as konini by Maori, are edible and taste like tamarillos. In New Zealand, possums love this tree fuchsia and have eaten it out of many locations.

Pacific wax myrtle

After passing through an ingenious deer fence gate made from woven tree branches on a wooden frame, the rest of the garden trails wind through pine forest, a fern canyon and a creekside path finally emerging at the Pacific ocean along the Coastal Bluff Trail. This area is open to black-tail deer and native plants like mahonia, salal, wild ginger, huckleberry and Pacific wax myrtle abound.

Sherman loved the Mendocino Coast Botanical Gardens as much as I. The gardens are located an on Hwy 1 just south of Ft. Bragg. If you are in the area at any time of year. take a stroll through. You’ll be glad you did.
