Great Grasses for the Santa Cruz Mountains

Sawtooth Mtns
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.

Dry River Beds – Beautiful & Beneficial

With so many people replacing their thirsty lawns with low water-use plants, I?m getting lots of requests for ideas about what to do with all that empty space. The sky?s the limit when you have a blank slate. Let me get you started.

If your old lawn was in the front you might consider putting in a sitting area for a couple of chairs and a bistro table. Use simple crushed gravel or more formal flagstone underfoot and surround the space with a low seat wall to add a bit of privacy.

Adding a dry river bed is another good solution. A dry river bed can slow runoff, spread it out and sink it back into the soil. Connected to a downspout they keep even more rainfall on your own property. If we get the El Nino storms that are predicted this will be a welcome addition to your landscape.

A dry river bed is a rock-lined swale that uses rounded river rock in addition to vegetation to allow

runoff to soak into the ground. Make sure there is a 2% slope from beginning to end to ensure that water is conveyed away from your house to the desired location. Non-woven geotextile fabric is often used underneath the rock.

You can create a depression or rain garden at the end of your dry river bed and plant it with plants that tolerate wet feet in the winter. Both a dry river bed and a rain garden allow water to sink back into the ground. The plants remove pollutants from the runoff from roofs or other impervious surfaces.

A rain garden might be a simple, shallow depression filled with plants that can flourish in both moist and dry conditions. The size and depth will depend on your how much water you need to capture in a winter runoff

Sometimes a dry river bed will receive so much runoff that a dry well or dispersal pit is installed at the end. If you have a high water table or clay soil the water may not always soak in fast enough and an overflow device like this is needed. The goal is to keep water on your own property and not in the street or the neighbors? yard.

There are good looking dry river beds as we?ll as bad looking ones. A quick Google image search will show you what I mean. Your goal is to create something that looks like it belongs right where it is. The plants, the accent rocks, the cobble, the location – all need to work together.

If your property has a natural slope follow the natural terrain if possible. You can install a dry river bed on flat land also by creating a channel for the river bed to follow. Keep in mind that even a dry river bed is more interesting if it is not all visible at once. Soft, flowing curves and bends create a natural look.

Start with the rocks and cobble. Rounded river cobble looks most natural for the creek bed. In nature, water flowing down a river would round off sharp rock edges to produce cobble of different sizes. A river never has just one size of rocks and yours shouldn?t either.

Accent rocks can be any type that you like as long as you get a variety of rock sizes and shapes. Use the larger stones to direct and channel water. Placing rocks on the outside of a curve creates a more natural look.

As in all gardens there is always a bit of maintenance to keep things looking and working great. Weeding in the first couple of months while plants become established is important. Replenish mulch as needed until the plants grow in.

Periodically remove leaves that have landed in your river bed and reposition rocks moved by runoff to keep your dry creek bed working for you when you need it. Also don?t start your dry creek bed too close to the foundation of your home if that area is flat. You can direct the water through a drain pipe connected to a downspout to a lower starting spot in your garden.

So whether you are adding a dry river bed to add interest to your lawn-free landscape or to double as catchment for winter storm runoff, make yours look like it?s always been there.

What to Do in the Garden in Wintry Weather

toyon-berriesTwas the weekend after Thanksgiving and all through the house, not a creature was stirring not even a gardener. I should probably do something productive, but what? Should I be good and do a little light weeding? Maybe I can muster up the energy to plant a few more bulbs. Come spring I?ll be happy I did. Then again I could make notes of my gardening successes and not so great horticultural decisions. ?I know?, I say to myself, ?this weekend I?ll revel in what I don?t have to do in the garden?.

I don?t need to prune trees and shrubs at this time of year. Other than clipping a few OLYMPUS DIGITAL CAMERAwell placed branches to use in a holiday wreath, I?m off the hook for this task right now. Deciduous trees are still in the process of losing their leaves and are not fully dormant. Evergreens shrubs and conifers can be trimmed lightly but most shaping is done when they start growing in late winter or very early spring.

The season is pretty much over for me except to enjoy what?s left of fall color and the ornamental grasses waving their seed heads in the wind. A lot of perennials are dying back but I?m not in a hurry to neaten things up. The seed heads left in the garden supply food for birds and other creatures while the foliage provides shelter for the plant in the cold and frost. Remove anything that has turned slimy or just plain unattractive but leave berries and seed heads for food and winter interest.

hakonechloa_winter2At this time of year my garden is visited mostly by chickadees, nuthatches and goldfinches. They will spend the winter here and I?m doing them a big favor by not cutting back brown foliage containing nutrient-rich seed heads. Some of the reliable seed producers that I won?t have to clean up this weekend include artemisia, aster, coreopsis, penstemon, sedum, lupine, salvia, black-eye Susan, coneflower, phlomis, monarda, agapanthus and grasses.

Chickadees gather hundreds of seeds in fall and early winter and store them in hiding places to ensure themselves a food supply later in the season. They are a remarkable bird that we take for granted being so common. I read in Audubon magazine a couple years ago that a chickadee weighs about as much as a dozen paperclips but their body is large for their weight. This means they have to ramp up the number of hours they devote to feeding. At night chickadees cram themselves into tiny cavities and shiver, burning the day’s fuel to keep from freezing.

Hummingbirds still need a nectar source at this time of year. Anna’s hummingbirds live in this area all year long. So In addition to the plants in my garden that supply nectar I keep my feeders up year-round and keep them clean.
They need your nectar even more in the winter when very little is in bloom. In addition to nectar rich natives like mahonia, my abutilons are a winter favorite for them.

Other tasks I can put off at least for this weekend include planting wildflower seeds. I see California poppies coming up all over the place. Nature knows when the time is right. Well, maybe I?ll broadcast a few working them into the soil very lightly. I need to hoe off some early weeds that would compete with them. How many calories aren?t burned in light gardening? I might just reconsider not being a total couch potato this weekend.
