Flowers from July till August/September.
Full sun, half shade, very adaptable to soil types and moisture - will grow virtually in any soil that is not waterlogged (sandy, rocky, shallower, loamy, clay). Average moisture (medium) to medium-dry.
Heat, humidity, drought and black walnut tolerant.
Deer and rabbit resistant, suitable for zones 5 to 8.
Native to eastern part of USA, see the USDA distribution map.
