Specifications
Never before available from flower seeds, Alternanthera is one of the finest foliage plants around for the sunny to lightly shaded garden, and 'Purple Knight' is far the best of the spreaders, with a purple cast that actually deepens with exposure to heat. The deep purple foliage offers a great contrast to flowering plants and various green foliages.
Purple Knight Alternanthera establishes nicely from flower seed, and it quickly reaches just 16 to 20 inches tall but spreads up to 3 feet wide. Marvelously heat tolerant, Alternanthera plants reach their deepest, richest tones in full sun, but will turn an interesting burgundy-bronze in partial shade.

How to Grow
Indoors, grow in loam-based potting compost (No. 2) in full light. In the growing season, water freely and apply a balanced liquid fertilizer monthly; in winter, water sparingly and keep well ventilated. Outdoors, plant out after any risk of frost has passed; grow in moist, but well-drained soil, in full sun for best leaf color, or in partial shade. Clip over to maintain compactness.
