Culture

Best grown in sandy, loamy, well-drained soil in full sun. Good drainage is essential, particularly in winter. This is a tap-rooted plant that tolerates heat, humidity, some drought and poor soils. Remove spent flower spikes to prolong bloom. Flower stems tend to become leggy and flop when grown in rich soils and/or part shade. Plants may benefit from close planting or support from adjacent perennials.

Noteworthy Characteristics

‘Passionate Rainbow’ is a compact pink-flowered gaura that is most noted for its variegated foliage. In 2001, it was discovered growing as a naturally occurring sport in a clump of Gaura lindheimeri ‘Passionate Pink’ in Victoria, Australia. It is a compact upright plant that forms a foliage mound to 12” tall featuring narrow, lance-shaped, medium green leaves (to 2.5” long) with creamy white margins and red-pink coloration toward the apex. New foliage may have pink overtones. Foliage is attractive throughout the growing season. Four-petaled red-pink flowers (1” diameter) bloom at the stem tips and side branches of wiry flowering stems rising well above the foliage mound to 24-30” tall over a long late spring to late summer bloom period. Flowers open a few at a time, and are often described as dancing in the wind like butterflies. U. S. Plant Patent PP17,002 was issued on August 15, 2006.
