Beautiful Borders
Yes--you can create beautiful
flower borders like the ones we all see in magazines -- even though
you live in a desert climate. You can
have flowers to admire in the garden for months on end or cut for
fresh bouquets in your
home. And it is easier than you might
imagine. Simply select drought-tolerant plants that are suitable for our
climate extremes, such as the ones we have listed and shown below.
Now here are some secrets to those
lush-looking borders you see in magazines: 1) group 2 or 3
of the same plants close together. When the grow they will
give the appearance of one large plant. And 2) plant your
flowers fairly densely. If you plant them far apart it may
take several years before the border fills in and looks good.
You can always transplant if your border gets too crowded.
Densely planted borders keep down weeds and help maintain moisture,
too -- which is particularly important in a desert garden.
A Lavender and Yellow
Border
Try some of these as a basis of a
drought-tolerant, xeriscape border that
has
predominantly gray-green foliage with purple, blue, lavender and yellow
blossoms. These plants need some water, of course, but many are considered
to be at the heart of a low water-usage garden. The
taller ones go in the back of the border; medium height in the middle; then the short ones at the front edge.

Coreopsis (Coreopsis grandiflora)
- expect golden yellow blooms for months if you pick off the old
flowerheads. These daisy-like flowers stand 1 to 2 feet tall and grow
easily from seed. Coreopsis self-seeds, so all you have to do is plant it once.
The coreopsis, right, are tucked into a terra cotta pot
between a trailing Licorice plant and Dusty Miller. |
Ozark Sundrops (Oenothera
macrocarpa)
- Long blooming primrose-like yellow flowers on a low growing
plant. Needs some shade. Unlike its cousin, the pink
Mexican Evening Primrose, the Ozark Sundrops is not wildly invasive.
 |
Lamb's Ear (Stachys byzantina)
- a low grower that is good for edging borders and it grows
fast and spreads quickly. Soft, fuzzy gray leaves. Small
purple flowers bloom from thick erect stems.
This lambs' ear in bloom shares a border
with varigated turf lily (Liriope muscari) and a sunflower
(Helianthus)

Artemesia (Artemesia 'Powis Castle') -
artemesias are native to the American west, and many are known by the
generic common name of sagebrush. The "Powis
Castle" variety was developed for use in areas that get regular
watering and can grow to 6 feet wide or more. The 'Silver Mound'
variety does less well in a
desert climate. |

Lavender cotton (Santolina incana)
- not related to lavender at all, this low growing gray or green
lacy-leafed
plant has a burst of yellow button-like flowers in early summer.
Should be trimmed back after blooming and even then it is a short-lived
perennial and quite drought-tolerant.
The santolina, shown, is nestled against purple petunias.
|
 |
Mexican Bush Sage (Salvia
leucantha) - another drought-tolerant gray-green plant with soft fuzzy leaves topped by
spires of intensely purple blossoms. Long blooming. It grows to 2 or 3
feet tall and flowers both
in Spring and Fall/Winter. Hummingbirds love these blooms and will feast on them
from dawn to dusk.
|
 |
Lavender (Lavendula) - a
lovely favorite in Mediterranean gardens. Sweetly fragrant purple
flowers. Will reseed itself and hummingbirds love it. |
Bearded iris (Iridacae) - select from dozens of
yellow, purple or white iris. After the short bloom
period in the spring, the leaves of bearded iris provide a nice vertical
element. A vigorous grower in our climate with
relatively little water needed, so give it some room to grow or you may
find yourself dividing the clumps annually.
Verbena (Verbena - various hybrids)
- this low
growing plant makes a pretty edge along a xeriscape border. Both annual
and perennial varieties are readily available in lots of colors,
including purple and lavender.
Then, for variety, tuck in clusters of annuals like
zinnias
or marigolds in sunny orange, gold and yellow. Include dark green herbs such as
rosemary or scented geraniums for fragrance and leaf color contrast. Or shrubs such as
white roses or tall yellow hollyhocks for an old-fashioned look.

What is
With This Latin Anyway?
The reason we include the botanical names for plants is to help
clear up any confusion. Different plants have the same common
names in various parts of the country. And the same plant
may have different common names.
We suggest that you use the botanical Latin name
as well as the common name when you are shopping for
plants so you will know what you are getting. By state
law, all plants for sale in nurseries have to have their botanical
(Latin) names
on them.

Got Weeds?
Pour a pan of boiling hot water on a weed to kill it. Be
very careful that the water does not splash on nearby
plants or on you. The boiling water should do the job within 24
hours.

Take the
Screwdriver Test
Not sure if you are watering your
lawn too much or too little? Then take an 8 inch screwdriver
and push it into various places in your lawn about an hour and a
half after you have watered. If the screwdriver goes in
easily, you are watering enough. You may even want to consider
cutting back a bit.
If you cannot push the
screwdriver all the way in, you need to increase the amount of water
for the lawn. Or you may want to simply replace
your lawn.

Make Better
Beds
The 3 absolute rules of desert gardening:
1. Improve
your soil!
2. Improve your soil!
3. Improve your soil!
Be sure to dig in compost or organic soil
amendments and add some balancing fertilizer before you plant
anything. Plants grown in soil rich in organic
materials are more likely to remain healthy and resist pests and
diseases.
