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.

Great Grasses for the Santa Cruz Mountains

Sawtooth Mountains, Idaho

Recently I took a road trip to see some of our great country. The Sawtooth Mountains in Idaho and the Grand Tetons and Yellowstone in Wyoming have been on my bucket list for a long time. In addition to the amazing places I visited and the buffalo, elk and bald eagles I got to see up close and personal I was able to take a look at passing gardens of people who live in harsh climates and get some tips on plants that survive and thrive in these conditions. If you are looking for tougher plants for your own garden to add this fall planting season here are some ideas.

Some of these plants are old favorites and some are new. There?s a reason a plant is used over and over again. It?s reliable and trouble free. Plants that are have low water requirements are a must, too.

Throughout the small towns I passed through as well as larger ones like Jackson Hole, Wyoming I again and again

saw Karl Foerster feather reed grass planted in landscapes along with the Black-eyed Susan variety Goldsturm.

Feather reed grass tolerates heavy clay soil unlike many of the other ornamental grasses. Forming a clump only 2 feet wide it can fit in a smaller garden without overwhelming other plants. Even in light shade it blooms early in June with tight, vertical flower stalks of feathery, purplish-green flowers which turn golden as the sterile seeds mature in summer. Feather reed grass looks good throughout most of the winter providing interest until cut to the ground just before the new shoots appear.

Besides texture, grasses provide color for your garden, too. Who hasn’t admired the burgundy foliage of Red Fountain grass? it’s one of our most popular grasses with fox-tail like coppery flower heads. Eaton Canyon is a dwarf variety that is root hardy down to 20-25 degrees. Plant it in full sun and irrigate little to occasionally. Be sure to cut this grass back in late winter even if it hasn?t suffered much from frost. The new growth will look so much better for this treatment.

Another grass I?m hearing a lot of good things about is called Pink Crystals or Ruby grass. Melinis nerviglumis has pretty blue-green foliage that forms a one foot tall clump turning puplish-red in the fall. Very showy pink flowers rise above the foliage in the spring and summer. This grass will tolerate considerable dryness.

Grasses are survivors and are good choices for sunny spots that get little irrigation. Good drainage is a must for these plants so amend the soil with plenty of organic matter before planting. Combine drought tolerant grasses with companion plants and a few accent rocks to complete your dry theme. Good combinations for these areas are Pheasant Tail Grass with the sky blue flowers of Russian sage. Giant Feather grass looks great with the purple flowers of penstemon ‘Midnight’. If you like blue foliage, try ‘Elijah Blue’ fescue grass with Amazing Red flax for a show stopping combination. Pink Muhly grass will stop traffic when in bloom.

Grasses are distinguished from other plant families by their growth habit. They grow upward from the base of a leaf or shoot and can regrow from the crown when cut back. True grasses generally have extensive root systems which help control erosion. There are other grasslike plants that resemble grasses in their growth habits and are often some of the best companions for interplanting with grasses. These include New Zealand flax, carex family sedges, chondropetalum, kangaroo paw and lomandra ?Breeze?.

Most grasses require little care, minimal fertilizer, only occasional grooming and just enough water to meet their needs. Diseases and insect pests are rare and they are not attractive to deer. They have succeeded because of their adaptability and have evolved to suit almost every environment and climate on earth.

The Changing Season of September

Japanese forest grass

You never know where new gardening ideas and inspiration can come from. The other day I stopped by to help a friend water a garden by the river in South Felton while the owners were out of town. We both enjoyed the unique combination of plants and garden art placed strategically though out the garden. It was clear that this soothing garden was created with love. If gardening keeps you sane, don?t stop because of the drought.

Covered with huge white, heavily ruffled flowers a Rose of Sharon ?Helene? anchored the entry to a small deck overlooking the San Lorenzo river. With a reddish-purple eye and handsome, leathery dark green leaves this attractive shrub will bloom nearly continuously over the summer and fall without setting seeds.

Other gems in this garden that caught my eye included a Japanese painted fern paired with a purple leaved coral bells. A foxtail fern and variegated hosta looked great nearby. Japanese forest grass, oakleaf hydrangea, liriope, helleborus and winter daphne grew among the ferns.

These are shade plants and most like a regular drink of water. They are combined with plants with similar water requirements in this garden but if your garden is in more sun remember that it doesn?t take a lot of water to make a garden beautiful. An garden_art.1920 Japanese_painted_fern-heuchera.1920unthirsty garden can fill you with joy.

Gardening makes us learn new things. If you water less frequently, some plants may decline or even die eventually. Remove those that do and replace them with plants that will thrive with less water.

Agastache ‘Apricot Sprite’

Some to try as replacements are agastache or Hummingbird mint. Plant near your organic edible garden to provide nectar for pollinators as well as hummingbirds. The flowers are edible as a salad garnish, in baked goods and in cocktails while their foliage can be added to herb salads or in a cup of tea.

Other perennials that bloom now and into fall include asters, gaillardia and all the salvias. California fuchsia are just starting their long fall bloom cycle, too.

I like the bright flowers of gloriosa daisy, especially the longer lived Goldsturm variety. These perennials make good cut flowers and are tough and easy to grow. They are descended from wild plants native to the eastern U.S. but require only moderate water once established.

Need more late summer perennials to extend your season? Coneflowers will continue to bloom until frost then go dormant for the winter. Now days there are many colors to choose from in addition to the traditional rosy purple daisies. They are lightly fragrant and make good cut flowers for bouquets. The clumps spread slowly and can be carefully divided after 3 or 4 years. If faded flowers are left in place, the bristly seed heads provide food for finches in winter.

The herb echinacea is derived from varieties of this flower. Echinacea purpurea and other varieties are used as a fortifier of the immune system, mainly to prevent flu and minor respiratory diseases by increasing the body’s production of interferon. The roots are the part of this plant used for medicinal purposes.

Echinacea was used by Native Americans more than any other plant in the plains states. It was used to treat snake and insect bites because of its antiseptic properties and to bathe burns. They chewed the plants roots to ease the pain of toothache. It was also used for purification. The leaves and the flowers can be used in teas as well.

Enjoy unthirsty color in your garden this fall.
