|KOCHIA scoparia forma trichophylla - 'Childsii' Burning Bush|
Chenopodiaceae, native to Eurasia.
Germination: Sow indoors at 70-75°. Sow 4-6 weeks before planting out and with no cover as light aids in germination. Seeds will germinate in 10-15 days. Seeds can also be sown outdoors in the spring after all danger of frost is past.
Growth: Transplant when there are at least two sets of true leaves. Space seedlings 18-24 inches apart in full sun in dry soil with excellent drainage. Fertilize moderately. Very tolerant of hot weather and in cool weather it is slow to establish. Shear to keep plants compact and tidy. Plants will self-sow around the garden.
Appearance and Use: A vigorous annual for use in the border, for hedging and screening, and as an accent. The dense, rounded habit in 2 1/2 - 3 feet proportions offers green, narrow, feathery foliage that turns red in the autumn. Grown primarily for its foliage as its green flowers are not showy.

"Plants vary in their heat stress tolerance, not only from species to species, but also from cultivar to cultivar. In addition, unusual seasons-fewer or more hot days than normal-will invariably affect results in your garden, as will extremely dry or humid conditions," Dr. H. Marc Cathey, with Linda Bellamy, Heat-zone Gardening, How to choose plants that thrive in your region’s warmest weather.
