Fall Blooming Perennials

Every garden changes over time.  Gardening is a process, a constant experiment so don't get discouraged when things don't go exactly as planned. For example, a cool spring may cause some things to bloom later while a warm, dry winter speeds up plant and flower development. Maybe that pink flowering tree now conflicts with the red blooms nearby. Whether it's caused by climate change or just the weather, take comfort that your garden can grow more beautiful each year with a little tinkering now and then.

At this time of year look to the following plants combined with ornamental grasses coming into bloom to carry your garden until autumn color from trees and shrubs kicks in. Go for dramatic extravagance with color combinations than inspire.

Russian sage.  Tall, airy, spike-like clusters , create a lavender-blue cloud of color above the finely textured gray leaves. This perennial has a long blooming season and the cool color of the flowers is stunning in the fall garden. There are several varieties available with different shades of soft blue to violet blue flowers. Most grow 3-4 ft tall. Little Spire Russian sage is a shorter, upright selection that doesn't flop over in the landscape. It adds a sense of lightness to the garden. You'll love the cool color on a hot day.

Aster x frikartii 'Moench'.  The lavender-blue flowers on this perennial can get 3" across and cover the plant with blooms from early summer to fall, even longer in mild winter areas if spent flowers are removed. They attract butterflies and make a good cut flower. This reliable, drought tolerant plant thrives in full sun, grows 2- 3 ft tall and is mildew resistant.

Agastache which is also called hyssop attracts hummingbirds, butterflies and bees to your garden It's also deer resistant. Aromatic foliage on Blue Fortune smells like peppermint-lemon when brushed or crushed. The flowers on Electra are vivid orange. Then there's licorice mint hyssop, orange hummingbird mint hyssop, anise hyssop and a whole slew of hybrids of every color in the rainbow- lavender, pink, apricot, orange, purplish, coral, powder blue, tangerine, red – you name it. Agastache is easy to grow in full sun or partial shade and is drought tolerant. Just be sure to provide excellent drainage.

Salvia-  the workhorses of the garden. Their long blooming season makes them right at home in the fall garden. There are some 900 species of salvias.  They are the largest genus in the mint family. Choose from many new cultivars like Dancing Dolls with rose and cream colored flowers. Another good choice is a Ca. native hybrid called Starlight that blooms with long white flower wands that really stand out at twilight.
There are lots of Salvia greggii varieties available such as Pink Frills, Golden Girl and Neon Dancer which has vivid rose and red flowers.  Salvias are drought tolerant and deer resistant (really). Although they tolerate some shade they looks best when planted in full sun. To encourage repeat bloom trim off spent flowers stalks when they start to look rangy. They will rebloom for months.

Another common plant from this huge family is the Mexican bush sage.  So showy that people mistake them for huge lavender plants. They are vigorous and upright growing to 3-4 feet tall and as wide.  Velvety purple and white flowers cloak foot-long stems. Salvia Santa Barbara is a compact selection that grows 2-3 ft high and spreads 5 ft wide. They stop blooming only when frost hits them.  To limit plant size and renew flowering stems, cut back close to the ground before spring growth begins.  You can't go wrong with these plants if you have a large space to fill.  Hummingbirds love them, too.

Perennials should be planted in multiples, not only for beauty's sake but also for lower maintenance. Let your trees and shrubs lend structure and year round interest with an explosion of perennial color that gets all the attention. Just don't hesitate to change what needs adjustment or transplanting if needed to a better location.

Ornamental Grasses

One of the most dramatic sites in a garden is an ornamental grass backlit by late afternoon sun. They seem to come alive as their tawny flowers spikes glow and sway in the breeze. This is what grasses are all about and why they are so popular. Who could resist?

Grasses are versatile plants and come in all sizes, from ground-huggers to shrub-like clumps. Some form upright tufts,  some look like mop-top mounds and others form arching fountains. They easily adapt to the same conditions most garden plants thrive in, rarely needing any special soil, preparation or maintenance. And more subtly, their gentle movement and soft whispering sounds can bring your garden to life as no other plants do.

Grasses serve many functions in a garden. If you want to replace your lawn and save water you can choose from California natives. Some are low like Carex pansa or sesleria while others like Festuca californica make great flowering accents and look their best massed in groups. Other good natives for meadows are Blue grama grass or Boutelous gracilis, Creeping wild rye or Leymus triticoidies, and Alkali sacation or Sporobolus airoides.

Both San Lorenzo Valley Water ( http://www.slvwd.com ) and Scotts Valley Water Districts ( http://www.svwd.org ) offer many tips and incentives to conserve water. There are lists on the website of water smart grasses. Their rebate programs offers several landscaping credits including  converting an existing lawn to water-wise grasses.  Both districts have guidelines and procedures to apply for the rebates on their websites.

My favorite shade tolerant varieties for meadows include red fescue, acorus gramineus or Sweet flag, festuca altissima, bromus beneckenii, and several varieties of carex-divulsa, blanda and texensis.

But it's the showy accent grasses that always gets my attention and Pink Muhly grass has got to be at the top of the list. A must have for the low maintenance garden this ultra-rugged, ultra-tough California native grass is topped in late summer and fall by enormous plumes of cotton-candy pink that can also be used in dried arrangements.

I like variegated plants and two-tone grasses combine well with many other garden plants. Miscanthus sinensis Morning Light is an especially refined and elegant ornamental grass. Fine leaf blades are green with clean, paper-thin, white margins that give the plant a silvery cast when viewed from a distance. It is luminous when backlit by the early morning or late afternoon sun. Morning Light tends to keep its upright shape better than some other cultivars and rarely flops. The reddish bronze plumes that appear in late fall are spectacular.

Another personal favorite ornamental grass is Stipa gigantea or Giant Feather Grass. This semi-evergreen grass grows 2-3 ft high and makes a stately specimen with narrow, arching foliage and shimmering gold panicles that reach 6 feet tall. The flowers open early in June as silvery-purple and mature to shades of wheat. Large plants in full flower are a spectacular sight. Their tufted, clumping form makes them suitable as accents anywhere. It takes drought once established but also will grow with regular garden watering. The beautiful flower spikes are good in dried arrangements.

Caring for grasses is easy. As a rule of thumb, if it browns in winter then cut it back before new growth starts. If it's evergreen by nature just clean up outside leaves. Most like well drained soil and are tolerant of a wide range of garden conditions. You shouldn't fertilize heavily because an excess of nitrogen can lead to lush, soft growth that tends to flop. Mulching with 2" of compost yearly will keep the soil and your plants in good shape. Water grasses regularly during their first year to help get a good root system established. Even grasses that are normally touted as drought-tolerant require a season or two to become fully established.

Hidden Gardens of Bonny Doon

Enter the Hidden Gardens of Bonny Doon with me as I preview several gardens that will be featured on the tour this coming weekend.  While some of our gardens have a few areas with a "wow factor" , the gardens I was privileged to visit have this element at every turn. I was amazed, impressed and truly honored to spend time in each of them.

First stop was a garden that took my breath away. Looking past the lush lawn, the view takes in all of Monterey Bay. It wasn't always this way, the owner explained. When she moved to the property in 1981, she didn't even know there was an ocean view. It was only after some judicious pruning that this stunning view was revealed.

We  ambled through the many paths that took us up close and personal with perennial beds overflowing with blooming iris, spirea, weigela, succulents, hardy geraniums, coprosma and coleonema to name just a few.

Rabbits are an ongoing problem in this garden. Seems they love her Angelina sedum, coprosma, and Rose Campion as much as she does. Little 12" tall fences surround several of the beds which looks comical but apparently works as the rabbits don't like to jump over them.

Stained urbanite has been stacked by the owner to make short retaining walls and the look is quite classy blending in the flagstone and gravel paths. She explained how easy it was to stain the broken concrete from the old driveway by slapping on some concrete stain. "Piece of cake", she told me.

Other flower beds she edged with Sonoma fieldstone, stacking them herself. At every turn you can see the personal touches that make a garden unique. An old rusty mailbox was tucked into one of the beds overflowing with blooming pansies and million bells calibrachoa.  I loved this garden.

Next stop was another garden 30 years in the making. You won't believe the "before" pictures when you see this garden now. I could barely see the potential in the old pictures but the owner could and started to build up the rock hard soil bed by bed. After many years she has created  an organic garden full of flowering rhododendron, roses, viburnum, herbs, vegetables, citrus, apples and a 5 year old  Staghorn fern that measures 4 ft across.

The owner explained that deer are not a problem because they won't jump the irregular picket fence. Seems the wide pickets confuse their eyesight. Unfortunately, the gophers have decided recently that after 14 years, her camellias are now on the menu and she has lost almost all of the original 40 in the past year. Instead of lamenting her loss, she sees it as an opportunity to add new plants. She has the optimism that all gardeners possess.

Chickadees nested in a box attached to the porch. Garter snakes and alligator lizards patrol the flower beds. A bathtub, sunk into the earth serves as "the poor man's hot tub". Old metal chairs are planted with flowers and ferns and other found garden art is sprinkled generously though out the garden. This is the garden of an artist whose studio is nestled back among the trees. At every turn you feel the peacefulness of this wonderful place. This is a garden to experience not just view.

The last garden I was lucky enough to preview, was an asphalt driveway just 6 short years ago. There are occasional unplanted spots that still show asphalt. What a transformation. With the help of lots of top soil and an auger this gardener has created a spectacular space.  "Everything grows like crazy here", she explained.

The front garden is open to deer and is planted with echium, leucospermum, arctotis, barberry, thyme, rosemary and New Zealand flax. One of her favorite plants is a huge variegated holly that buzzed so loudly with bees I thought the electrical line coming into the house was making all the racket.

In the back, a small orchard edged the fence. Blooming lilacs by the deck heavily scented the air. Succulents intermingle with peony, erysimum and gaura. This gardener explained she " she is one of those people who buys whatever she likes and then finds a place for it". Having had previous experience growing grapes and olives in Sonoma, she is a hands-on gardener who does it all herself. She's a self-described  "drip queen".

A ceramic artist, her sculptures are focal points though out the garden. There is a lot of other garden art in this garden, too.

Where do these gardeners find the garden art, water features and other items that give their gardens that personal touch? One explained, she is always on the lookout for estate sales as she drives around or sees advertised in the paper. "That's were you can really find the treasures", she explained. "Little old ladies have some great plants and other wonderful finds in the back of the garden".

The Hidden Gardens of Bonny Doon Tour takes place Saturday and Sunday, May 19th and 20th. Don't miss it.
