Great Plants for a California Garden

Our local UCSC Arboretum is a place everyone can enjoy. You can marvel at the dozens of jewel-tone hummingbirds darting about feeding on nectar of colorful flowers while strolling the gardens for new plant ideas.

There are still lots of dramatic leucospermum in bloom as well as California native plants that flower mid to late summer. The rainfall last December helped many of the drought tolerant plants grow more foliage and put on a better show this year. The hummingbirds couldn?t get enough of the erica blooming in shades of pink, orange and red. There must have been a dozen darting about feeding and chirping between the shrubs.

If you are looking for some inspiration for new low water-use plants you haven?t tried the nursery at the Arboretum has a good selection. They replenish the stock from their growing area on a regular basis so there?s always something to catch your eye. Here are some that I plan to grow myself or recommend to others.

Hemiandra pungens

Color in the garden is something we all relish. One of the plants that caught my eye is called Hemiandra pungens. Pretty lavender-magenta flower clusters cover this small one foot plant. It?s drought tolerant although it looks better with occasional summer water.

This bright little shrub is another of the plants from Australia being trialed at the Arboretum. The Koala Blooms plant introduction program is a joint venture which include growers here and in Australia. Plants are evaluated for their beauty, durability and sturdiness with regard to drought, weather extremes and variations in soil types. Out of the trailing process new plants are selected and offered for sale to the public.

Pimalea_ferruginea-Bon_Petite.1600

Another showy perennial that?s sure to make it?s way into the next appropriate garden I design is Pimelea ferruginea ?Bon Petite?. Bright pink umbel blossoms cover this small plant for many months starting in the spring. It?s hardy down to 25 degrees and requires little water once established. Also originating in Australia it looks great in a native low water-use cottage garden.

The common name for this plant is pink rice flower. The pot in the arboretum nursery happened to be placed near a red mimulus but it looked great even though you might think the color combination would be all wrong. Nature has a way of making things work despite the rules of the color wheel.

Several varieties of correa – also called Australian fuchsia – caught my eye. Although the flowers of this plant resemble fuchsias they are not related. Some do best with regular watering during the summer but the lovely correa pulchella ?Pink Eyre? is drought tolerant once established. Grow this three foot compact evergreen shrub in partial sun where it will bloom from fall through springtime and provide nectar for hummingbirds during the wintertime.

Salvia_guarantica.1600

I was also drawn to the brilliant cobalt blue flowers of salvia guarantica. This plant is worth growing – in sun or partial shade – even though you might need to cut it down to ground level after each winter like Mexican bush sage. Growing four to five feet tall it starts blooming in early summer and continues till frost. They also do well in containers and are a favorite of hummingbirds.

Prostanthera was well represented with three varieties – ?Poorinda Bride?, ?Purple Haze? and my personal favorite, the Variegated Mint Bush. They are all good choices for colorful, easy to grow, hardy shrubs that require only occasional irrigation.

Among other choices at the Arboretum nursery were stand-by’s such as lion?s tail, Mexican marigold, Germander sage, Copper Glow New Zealand tea tree and giant buckwheat. This local resource offers a cornucopia of inspiration.

Tips for New Landscaping after Replacing a Lawn

Tired of looking at that brown patch of lawn and trying to convince yourself it?s a badge of honor in these times of drought? You tell yourself ?It greens up in the winter so I?ll water just enough to keep it from totally dying now?. But wouldn?t a beautiful, sustainable, low water use garden be a more inviting place to spend your free time?

Replacing a lawn that is not used anymore can be the first step in a whole new kind of landscaping-a landscape that looks like it belongs where you live. Here are some very good reasons to lose the lawn and benefit the planet at the same time.

Even in years where we have normal winter rainfall we always have a seasonal drought. It?s called summer. Without our usual winter and spring rains, though, even native trees and shrubs are struggling. All the more reason that plant selection now is even more critical than before.

You?ve see pictures of some not-so-great looking lawn replacement projects. A drought tolerant plant here, another there, add an accent rock and that?s supposed to thrill you when you come home for the day? What?s missing is a garden designed to enhance our natural environment. When you remove your lawn, it?s a wonderful opportunity to not only create a garden than conserves water but also provides habitat for wildlife including birds and butterflies and improves the soil.

A living landscape does as much for our own pleasure as it does for the environment. It increases biodiversity of plant, animal and insect populations. It fosters healthy soil which can hold more moisture by supporting microbes and insects. Healthy soil can filter pollutants and improve water quality.

Think of using native and well-adapted, non-natives that connect with the natural landscape. Use tough plants on the edges and group greener, low water use plants closer to the house. Here are some good plants to use in a lawn-less landscape that won?t break your water budget.

When planting time rolls around this fall consider a green carpet of blue grama grass. This native sedge can provide a green carpet on much less water and can be mowed or not. It?s on the list of approved water-wise grasses eligible for rebates from our local water districts.

Another ground cover eligible for lawn replacement rebate is dymondia. I love the grey foliage of this low ground cover. It fills in nicely between stepping stones or can take light foot traffic in larger areas.

For a taller look that you don?t need to be able to walk on, the ground cover forms of ceanothus, manzanita or creeping rosemary are good very low water alternatives to a lawn. I have a very low Hearts Desire ceanothus that hasn?t been watered yet this year and it still looks green and lush.

Native yarrow, penstemon and salvia are the work horses of the garden needing little water once established and attracting all sorts of insects and birds. Other natives on the 800+ Approved Low Water Use Plant list include Pacific Coast iris, helianthemum, libertia, santolina, California fuchsia, rockrose, lavender, myoporum, coffeeberry, teucrium, verbena and kangaroo paw to name just a few. You can download the list from www.sv.org or www.slvwd.com.

I am not a big fan of artificial lawns. They do not provide habitat for wildlife, beautify our environment or improve the soil. They get significantly hotter than the surrounding air temperature contributing to the heat island effect by increasing air temperatures. Also artificial turf is a synthetic material with a relatively short lifespan ranging from 10-20 years and will eventually end up in a landfill. They can not be recycled. There are many other beautiful, low water use options that result in more sustainable and beneficial landscapes.

Water and soil management as well as plant selection are key to water conservation in the landscape.

Planning for the Dry Season – Step One: Lose the Lawn

low water use plantings2Front and center in the news and in your garden is the drought and what you can do about it in your own landscape. If you?ve dabbled before with replacing thirsty plants with climate-appropriate low water use California native plants or those from areas similar to ours this is the year to step up your efforts.

Gov. Brown?s mandate for water conservation state wide is a call to action to transform our landscapes into resilient gardens that not only save water but act to build the earth into a living sponge that harnesses rainwater and replenishes the aquifer.

Replacing that water guzzling lawn now that the kids have grown or dramatically reducing it?s size is a good place to start and is easier than you think. If you?ve been paralyzed with the thought of digging out and hauling away hundreds of square feet of heavy sod or using dangerous grass-killing chemicals, sheet mulching is the method for you.

This simple technique eliminates the lawn by smothering it with layers of recycled, compost and renewable materials. Here?s how to do it:

1. Mow the lawn down to 1-2?, leave the clippings in place and soak with a hose. Don?t worry. This soaking is nothing compared to what you?ll soon be saving by removing your lawn.
2. Flag the locations of sprinkler heads you will be keeping for your new plantings and cap off the ones you won?t need.
3. Add an inch of compost to speed up the decay of the grass. If your lawn borders a driveway, path or sidewalk you?ll have to remove about 3? inches deep of soil along these edges and back 8-12? so that the new mulch doesn?t slide off into the sidewalk.
4. Put down 2-3 layers of newspaper or one layer of cardboard overlapping the edges by 6-8? to prevent regrowth at the edges. You can buy recycled cardboard in rolls for larger projects or find your own at appliance or bicycle stores. Wet the cardboard or newspapers to keep them in place as you go along. It?s best to use cardboard or newspaper that will break down quicker. Weed fabric is not recommended as it takes much longer to break down. Don?t use plastic sheeting because water and air cannot penetrate it.
5. Add a 3? layer of mulch such as bark chips from a tree trimming company. You can use compost, straw or shredded plant matelow water use plantingsrial. If you have Bermuda grass or other weeds like oxalis you will need to layer about 8?of mulch to smother them.
6. Water thoroughly.

If you can wait a month or more to let the decomposition process get going so much the better. If you just can?t wait you can begin planting now by scraping away the mulch and poking a hole in the cardboard or newspaper where the plant is to go. Then add some compost to help the new plant become established. Be sure to plant high enough to prevent crown rot and keep the mulch a couple inches away from the stem. The top of the root ball should be 1-2? above the soil and just below the mulch.

Modify the sprinkler to drip and remember to adjust your irrigation system run times to accommodate your new plantings.

This is a basic ?lasagna? method for lawn removal. If you are planning to replant with water smart grasses you would choose finer composted mulch instead of bark chips. Either way the process works on the same concept as a compost pile. As the lawn dies from lack of light, it decomposes with the activity of beneficial worms, insects and microorganisms coming up from the soil and doing their job to break down the nitrogen and carbon in the sheet-mulch layers. It?s a win-win situation for the environment and your water bill.
