full to some shade, especially in the hot afternoon sun, some shade will help the deep colors last longer

2 by 1-2 feet (H-S), upright
Maintenance
grow plants where there is good air circulation to help avoid an onset of mildew, water early to allow the foliage to dry, water at the base when possible, dead head to promote more flowers and to prevent volunteer seedlings, the seedling will not be true to the cultivar type and usually are a magenta color, if needed spray with a fungicide, dead heading helps eliminate volunteer seedlings
Propagation
stem cuttings, root cuttings, easy by division in the spring, will not come true from seed
