Best practices for survivability and field observations

Many mentioned that it is long-lived (particularly if watered), a “great choice,” a “hammer” for green breaks, and can handle the heat and wind. Several mentioned its drought tolerance (although there are limits to its survivability in extreme drought), while one cautioned against over-watering. One noted that it is slow growing (possibly not able to outcompete weeds). It seasonally flowers, and is used culturally for medicinal purposes and for dyes.

Stressors and pests

Many noted its susceptibility to pests such as “mealybugs, snow scale, whitefly, lobate lac scale.” One recommended that to prevent it becoming “a pest magnet,” grow the species “in nearly full sun without too much water.” Another observed that if it is not completely damaged after fire, it will resprout. It is susceptible to goats and deer, which will eat seedlings and younger plants.

Availability and propagation

Many noted its wide availability via propagating from seeds (if the timing is right) and cuttings. One noted that “seeds keep for a long time.”
