Care guide

Quick ID

Small ornamental maple (*Acer palmatum*). Laceleaf / dissectum cultivars such as 'Crimson Queen' form low, weeping, finely-dissected mounds.

Sun & Site

Prefers part shade — afternoon shade matters in Draper's hot, high-UV summers to prevent leaf scorch, especially for laceleaf types. Keep soil consistently moist; protect from drying wind.

Pruning & Shaping

Minimal pruning. Thin for structure in the dormant season; avoid heavy cuts. For laceleaf forms, light shaping enhances the cascading habit.

Notes

A Crimson Queen in a full-sun bed (as in NW3) may show afternoon leaf stress — watch for scorch and consider afternoon shade if it struggles.
