How to grow
Plant in fall or spring in soil that stays moist — this is a streambank plant that sulks in dry sand. It wants real winter cold for best color, so in Florida it's strictly a north-Florida experiment; south of zone 8b, admire it in photos. Cut the oldest stems to the ground each late winter — new growth has the brightest red bark.
Water & feeding
Loves consistent moisture; mulch heavily and don't let it dry out in summer.
Common problems
- Leaf spot and powdery mildew in humid, airless spots
- Canker on stressed stems
- Florida heat — the whole plant is the problem south of the Panhandle
Harvest
No fruit worth mentioning (birds get the white berries). The 'harvest' is the pruning — coppice a third of the oldest stems yearly for maximum winter red.
Nerdy fact: The red color isn't paint — it's anthocyanin pigments in the bark, the same compounds that make fall leaves red, working as sunscreen for the stem tissue.
