Plants that can withstand the heat and survive with little
water are recommended for the area. There are several annual and perennial
choices for the Golden Plains Area. Annual plants that survive in a very dry,
hot condition include Bachelor Buttons (Centaurea cyanus), Moss Rose (Portulaca
grandiflora), Star or Crystal Zinnia (Zinnia augustifolia), Salvia (Salvia
greggii), and Verbena(Verbena bonarienis). Perennials that do well in hot dry
conditions are Blue Flax (Linum perenne), Hardy Four-O-Clocks (Mirabilis
multiflora), Hardy Cactus (Hardy cactus spp.), Beardtongue /Penstemon
(Penstemon spp.), Russian Sage (Perovskia atriplicifolia), Prairie Coneflower
(Ratibida columnifera), Blanket Flower (Gaillardia aristata/grandiflora), and
Golden Paper Flower (Zinnia grandiflora). These hardy annuals and perennials
require little water to survive. They do very well with about a half-inch of
water every 2 weeks.
Proper soil preparation before planting will help
plants thrive even in hot dry conditions. Adding a soil polymer to the soil
will help the soil retain moisture and keep plants from drying out. Working the
polymer into the soil close to plant roots after plants are planted will help
with moisture retention. Mulching around the plants with fiber mulch will also
help hold moisture in the ground so water is conserved. Feeding the plants with
a water-soluble plant food once to twice a month will also promote growth and
give added nutrients.
