Changing Times – Changing Gardens

Maybe our gardens in California should never have looked like a Monet painting filled with layer upon layer of water thirsty perennials and lush green lawns big enough for a soccer match. Because we were first settled by Easterners who could grow these plants with natural rainfall I?m going to give us a pass. It wasn?t our fault. But now we are wiser and smarter. We may have been kicking and screaming at first but all us us now accept that water is limited and we need to use it wisely.

That doesn?t mean, however, that we have to live in graveled yards with no landscaping. Our goal should be to figure out what the new California landscape should realistically look like and plant accordingly. We can still be surrounded by green and silver foliage and colorful flowers that look lush without breaking our water budget.
Look outside the old box and discover a whole new plant palette and a way of gardening that works for all of us.

Drought tolerant plant plugs

Recently in the mail, I received a collection of low water use, low maintenance plants native to Australia. I plan to trial the small plugs in my own garden but I know already that they are going to be winners. I have seen a couple of them at the wholesale nurseries. Others are improved selections of known tough, drought tolerant plants. They are well suited to our Mediterranean climate, easy to grow in well drained soils and hardy in winter. I?m looking forward to a time when they are available in local nurseries. In the meantime, I plan to specify them where appropriate in future landscape designs.

I?m excited about all 5 varieties of plants I received. Three are grass-like and the other two are compact versions of well known shrubs.

You might be familiar with the compact bottlebrush ?Little John?. Breeders now have come up with a new improved version called Callistemon ?Better John? because of its vigorous growth and dense blue-gray foliage. This 3 foot tall by 3 feet wide shrub is easy to grow, quick to establish and is long lived in the landscape. Hummingbirds love the 4-6 inch long red flowers during the spring.

The other shrub variety I am going to test is Westringia ?Grey Box?.? Westringia are deer resistant and very drought tolerant once established and ?Wynabbie Gem? and ?Morning Light? have been popular for years for this reason. Grey Box is a new dwarf form with beautiful grayish-green foliage. It doesn?t need pruning to keep it at 3 feet tall and wide. From late winter to summer, white quarter-sized flowers appear in small clusters along the stems. I?m anxious to grow this shrub myself.

lomandra
Lomandra ‘Breeze’

A couple of the grass-like plant plugs I received are an favorite of mine. I?ve seen lomandra ?Breeze? growing in heavy shade and also in sun. Deer don?t like it and it looks great with little water. Now there?s a new cultivar called ?Baby Breeze’ which stays at a graceful 18 inches tall. If you want the look of a short grass with no maintenance Lomandra is the new go-to plant. It even has yellow-orange tiny flower spikes in late spring.

Lomandra ?Katrinus Deluxe? is the other selection I?m going to grow out. It?s extremely drought tolerant, very shade tolerant, cold and heat tolerant and deer resistant also. It looks like an ornamental grass but you don?t have to cut it back in winter. It?s evergreen even when temperatures drop into the teens.

Dianella ?Little Rev’ is the last plant I?m looking forward to growing. This flax lily has an weeping architectural habit. It?s a very tough and drought tolerant grass-like plant good for erosion control as well as planting on it?s own or in groups. In spring it blooms with masses of small dark violet flowers. This is a clumping plant for full sun to partial shade that slowly spreads by rhizomes. As with the others this plant also is low maintenance and requires little water once established.

I?ll keep you posted as I discover new plants for our changing times and changing gardens.

Screen the Neighbors with Low Water-Use Plants

We all enjoy privacy around our homes. Even if you?re best friends with your neighbor you don?t always want to wave at them each morning in your robe. Whether you have a property tucked way back in the forest with a next door neighbor that looks right down on your deck or a postage stamp size lot that could be an jewel if you just had a screen between you and the next property, there are techniques designers use to make your home a private oasis.

azara microphylla

Narrow spaces can be challenging when you need to screen the house next door. There?s not room for a big, evergreen tree or hedge to solve the problem. One way is to use plants that can be espaliered against a fence or trellis. Some plants like azara microphylla naturally grow flat without much coaxing on your part. This small dainty tree is fast growing and reaches 15-25 ft tall. The yellow flower clusters will fill your garden with the scent of white chocolate in late winter. They are ideal between structures. I?ve used the variegated version to screen a shower and it?s working great.

Another small tree, the Compact Carolina cherry laurel can be espaliered also in a narrow space if needed. It grows 10 ft tall but that may be all you need to screen the neighbor. They are drought tolerant once established, deer resistant and the perfect host for birds, bees and butterflies. The leaves smell like cherries when crushed which gives this plant it?s common name.

A dwarf tree that also works nicely in this situation is a Southern magnolia called Little Gem. Naturally a very compact narrow tree it grows to 20-30 ft tall but only 10-15 ft wide. It can be trained as an espalier against a wall or fence and the sweetly scented flowers will fill your garden with fragrance.

Other small trees that make a good screen are purple hopseed, and leptospermum ?Dark Shadows?. Both have beautiful burgundy foliage. California natives that can be espaliered against a fence include Santa Cruz Island ironwood, Western redbud, mountain mahogany, toyon, pink flowering currant, Oregon grape and spicebush.

If you have a wider space to grow screening plants, one of my favorites is Pacific wax myrtle. This California native grows quickly to 30 ft tall with glossy, rich forest green leaves. Its dense branches make a nice visual and noise screen for just about anything or anybody. I?ve never used the subtle spicy leaves for flavoring sauces but I might try it next time a recipe calls for bay leaves. Best of all the fragrant waxy purplish brown fruits attract many kinds of birds.

Italian buckthorn is another evergreen screening shrub to consider. It reaches about 15 feet tall by 6-8 ft wide and has low water needs. It can grow 2-3 feet in its first few years making a quick screen. There?s a variegated version with stunning foliage that looks awesome mixed with the green variety in a hedge.

Another favorite hedge plant, the California coffeeberry grows 6-8 feet tall and gets by with very little summer water once established. Birds love the berries.

I also like osmanthus fragrans for a screen with a sweet scent and pittosporum ?Marjorie Channon? or ?Silver Sheen? with their showy variegated foliage.

If it?s just not practical to screen the perimeter of your property redirect your line of sight to keep attention focused on the garden instead of on the landscape beyond. A recirculating fountain as simple as an urn spilling onto cobbles at the base can disguise noise and become the focal point. There are lots of ways to add privacy to your home.

Plant Secrets You Can Use from Fox Island, Washington

deer_Japanese_mapleA year or so ago I planted a special kind of Japanese maple in my sister?s landscape. I traveled up to her house recently to celebrate our birthdays which are only 2 days apart and to check on the maple?s progress. Prized for their their brilliant salmon red bark which is much brighter than the regular coral bark maple, my sister?s Beni Kawa Japanese maple is coming along fine. I forgot to buff the bark with a soft cloth to polish it which keeps the color bright but I?ll be sure to remember that next summer when I visit again.

I also wanted to check in on her neighbor?s organic garden that I wrote about last summer. Bob was happy to show me what?s in the works for this year. Although he was fighting a cold -you can?t keep a good gardener down- he shared a few tips he is trying out this year.

Raw sawdust is his magic weapon in the strawberry patch. Sprinkled between the strawberry plants it is said to prevent annual weeds from germinating. He?ll get back to me with the results later in the season. His grapes were nicely pruned, the raspberries just starting to bud and the garlic which he planted last fall was about a foot high. The raised veggie boxes have been planted with lots of peas. Inside the green house, several types of kale and lettuce were just emerging in their flats.

Bob told me that this year again everything seems to be about 3 weeks early- sound familiar? As I walked the neighborhood enjoying the various blooming plants and taking in the sights of majestic Mt Rainier and the Puget Sound I admired many plants that also thrive here in our neck of the woods. A plant that grows in a multiple of growing conditions is always a winner in my garden. Here are a few notables from Fox Island.

What could a plant that is iconic of Scotland have in common with erica_canaliculata_Rosea.1600our area? Easy to grow heather and true heath look great in the garden at any time of year. Although both belong to the Ericacaea family, they are botanically different and are divided into the Calluna genus and the Erica genus. In the garden, however, they are nearly identical in color, shape and growing habits.

I love their colorful foliage and flowers and have seen the true heath, Erica canaliculata ?Rosea? blooming now also in gardens in our area. It is tolerant of winter lows a bit less than 25 degrees and will thrive in soil that is more alkaline than the calluna vulgaris heathers. Calluna types need more organic matter in the soil to really do well. Our acidic mixed redwood soils provide this and calluna cultivars are very cold tolerant. All need good drainage.

pieris_Valley_Valentine-closeup.1600Another shrub that I admire where ever I find it is Valley Rose? Lily-of-the-Valley. The other vivid rose variety which grows a bit taller is Valley Valentine. It seemed most gardens on Fox Island had at least one of these beautiful plants in full bloom including the stunning white flowering forms. Books might tell you they require average water but established specimens are remarkable tolerant of drought.

Although it wasn?t blooming yet I came across a lovely choisya Sundance choisya_ternata_Sundance.1600also called Mexican Orange Blossom shrub which describes the fragrant orange blossom-like blooms. The new growth of this fast growing, evergreen, deer resistant shrub is colored bright chartreuse and provides year round color to the garden.

To round out my tour of local rhodie_pink_early.1600landscapes on Fox Island many of the early rhododendrons were starting to bloom. Covered with vivid pink flower trusses they looked great planted with viburnum davidii, daffodil and narcissus, iberis and black mondo grass. All grow great in our area too. We have a lot in common despite the distance between us.
