Growing conditions
Its drought tolerance is rated none — it needs reliable moisture. It is recorded on soils from pH 5 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 1.
Size and growth
At maturity it reaches about 3 ft, making it roughly waist to chest height.
Bloom period
USDA records a bloom period of June. Flowers are red.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, coarse in texture. Its flowers are not conspicuous — a plant for form and foliage. USDA rates its lifespan as short, so plan on replacing or resowing it rather than treating it as permanent structure.
What the site needs to provide
USDA records it across sites receiving 7 to 90 inches of annual precipitation. The low end of that band is genuinely arid, so it has a wide tolerance for dry country. It needs at least 60 frost-free days to finish its season. It roots to at least 12 inches.
Propagating it
Cuttings is the only propagation method USDA lists. Its seed spreads at a rapid rate.
Resilience and wildlife
Browsing animals find it highly palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated medium. Its growth form is recorded as thicket forming.
Role in a guild
Shrub layer. In a layered planting this is woody mid-level structure between the understory and the ground. The layer is derived by a fixed rule from growth habit and mature height.
