Culture
Best grown in sandy, loamy, well-drained soils in full sun. Good drainage is essential. A taprooted plant which tolerates heat, humidity and some drought. Remove spent flower spikes to prolong bloom period. Thin flower stems tend to become leggy and flop, particularly when grown in rich soils, and plants can benefit from close planting or support from adjacent perennials. Plants (particularly those which typically grow tall) may be cut back in late spring by 1/2 to control size. May self-seed if spent flower stems are left in place in the fall.
Although the species will self-seed, this cultivar will not come true from seed.
Noteworthy Characteristics
Gaura lindheimeri, commonly called gaura, is a herbaceous clump-forming perennial that is native to Texas and Louisiana. It grows to as much as 5' tall on stems clad with spoon-shaped to lanceolate leaves (to 3" long). Pinkish buds along wiry, erect, wand-like stems open to white flowers which slowly fade to pink. Flowers appear in long, open, terminal panicles and open only a few at a time. Narrow, lance-shaped, stemless leaves (1-3" long) are occasionally spotted with maroon.
The genus name Gaura comes from the Greek gauros meaning "superb" in reference to the beautiful flowers.
Specific epithet honors Ferdinand Jacob Lindheimer (1801-1879), Texas plant collector.
KARALEE PETITE PINK is a compact (petite) cultivar that features pink flowers and red-tinged foliage on wiry stems typically growing to 10-14” tall. This is a vase-shaped perennial with 4-petaled coral pink flowers (1” diameter) that appear in wand-like panicles above the foliage over a very long late spring to autumn bloom period. Flowers open a few at a time, and dance in the wind like butterflies. Narrow lance-shaped leaves (1-3” long) are medium green tinged with red.
Problems
Root rot may occur in heavy and/or poorly drained soils. Rust and powdery mildew may also occur. Watch for aphids, whitefly and flea beetles.
Uses
Effective in sunny borders. Best in groups or massed. May be grown in containers.
