Gardeners' Notes:

Neutral SW_gardener On Jan 18, 2007, SW_gardener from (Zone 6a) wrote:

Quoted from Garden Store 'N' More "This deliciously rare old-world tropics annual was introduced by Jefferson he sowed seeds of this tender annual along his Roundabout flower border in 1811, calling it "Scarlet Mallow." This handsome plant of the Old World Tropics, rarely cultivated in America, has brownish-green stems and scarlet, mallow-like blossoms that open at noon and close at dawn. Direct sow or transplant to a sunny location after the last frost. Grows to five feet. Multi-branching with a strong, upright central stem, it bears interesting & attractive long narrow foliage. Easy to grow & tolerant of wet or dry soils, this lovely rarity may very well act as perennial in warmer temperate climates."
