PERENNIALS FOR TEXAS LANDSCAPES
Perennial plants may be defined as those which endure or persist
from the same root part year to year. Once a prominent part of nearly every
Texas landscape, perennials are often overlooked by today's gardeners and nurserymen.
Although many species still can be found in private gardens, their availability
is often restricted to sharing among friends and neighbors.
Most perennials are easily propagated by division, seed or cuttings.
Division is particularly successful since it not only provides new plants but
is often necessary for the continued vigor of plants. Perennials can be highly
useful and attractive in the home landscape. They often persist for many years
and usually require less maintenance than annuals. They can provide long seasons
of color and cut flowers while enhancing overall landscape development. If a
perennial border is more than you care to attempt as your initial experience
with perennials try adding a few to existing plantings. Many perennials have
attractive foliage and are an asset even when not in flower. Division is an
important cultural requirement of many perennials. Without an occasional thinning,
most of these plants will slowly lose their vigor. Most perennials will tolerate
relatively poor growing conditions but respond very favorably to well-prepared
planting areas containing high percentages of organic materials and moderately
high fertility rates.
