The warning signs are
flashing. At a time
gardeners are itching to get out in the garden, water levels are
dangerously low, causing some gardeners to worry about what to plant.
Many gardeners may be considering planting true drought-tolerant and dry
soil plants as if they live in Arizona, but West Coast horticultural
consultant
Joe Seals
warns gardeners to resist the this temptation.
“These plantings may be in trouble on the East Coast in your
average years of rainfall,” he explains.
To help alleviate this dilemma, he recommends home gardeners might want
to stick with annuals, some bulbs, and quick perennials to slide them
through this temporary condition.
Ball Horticultural’s
marketing manager
Jeff Gibson
agrees that using drought-resistant plants is a key strategy for those
planting in drought conditions. He urges careful selection of plants
that perform under extreme conditions.
“Lots of our Simply
Beautiful line of annuals, although not true draught tolerant
plants, can stand up to heat and dry conditions,” Gibson says. “These
plants were selected because they are tough, easy to grow and require
little maintenance, even in a dry year. “
Gibson recommends Lobelia Periwinkle Blue, considered the most heat
tolerant of all the lobelias. Unlike
most lobelias, it grows in the sun or shade, which is a big deal for
lobelia lovers. Galleria®
Geranium is a great heat tolerant trailing geranium that works well in
hanging baskets, mixed containers or window boxes.
Angel Mist® Summersnapdragon ‘Angelonia’ is a beautiful flower that
looks like miniature orchids blooming from upright spikes. This virus
free annual can take lots of heat.
“Butterfly
Penta is a big star in the heat and provides vibrant colors when
everything else is wilted and brown,” says Gibson.
“This flower is tough as nails and well suited to dry and
extreme conditions, and attracts butterflies, hummingbirds and honey
bees.”
According to Jacqueline van der Kloet, Dutch bulb designer and a founder
of the award-winning on-line bulb resource site, TulipWorld,
says if the draught continues, gardeners should order anemones,
daffodils, tulips and crocus this spring for fall planting.

All of these bulbs are adapted to growing with water from snow or even
less and going into a natural drought-resisting dormancy come late
spring into summer.
For larger trees and shrubs,
Scott Vergara
of The Conard-Pyle
Co.
, famous for their Star Roses, says the key is planting right in the
beginning.
“No
matter how drought resistant the plant is, plants must get established
from the beginning,” says Vergara.
“When you plant use a good organic mix, mulch, mulch, mulch and
water well.” Vergara adds it takes better part of half a season to get
plants established, even ones that are drought tolerant.
For trees, it could take two to three years.
Conard-Pyle’s rule of thumb in its commercial nursery is to water once
a day for a week, once a week for a month and once a month for a year.
If Mother Nature waters for you, skip that week, unless it was a
light shower, which you should follow by a good soaking.
Vergara emphasizes that, upon establishment, most Star® Landscape Roses
can handle long dry periods. Knock
Out™, a hot pink 2000 All-American Rose Selection winner, and Carefree
Sunshine™, a bright yellow single petaled rose, were bred for tough
conditions. They both are
extremely drought-resistant.
Other shrubs that are particularly drought resistant – once
established – are Epimedium 'Purple Pixie', Caryopteris ‘Grand
Bleu’, Euonymus ‘Emerald Surprise™” or ‘Moonshadow’ and
Juniper ‘Gold Lace’ and ‘Emerald Sentinel™’, which is a native
to the East.
Drought tough perennials are yuccas and any plant in the sedum family.
Both are hardy and undemanding and nearly all have the ability to
tolerate drought and poor soil. Yuccas in all their great cultivars are
so drought-resistant they will bloom (after settling in) without rain
since their tap roots go so deep.
Vergara adds one more caveat that may seem a bit strange coming from a
grower.
“Don't buy more than you can take care of,” he advises. “Invest
your money wisely. Buy what you can get in the ground, water and care
for realistically. Then buy
more later, after the first wave is established.”
