Vegetative Growth
6-12 monthsShrub develops dense branching structure; foliage becomes more prominent. Leaves show increasing red coloration as temperatures cool.
Maintain moderate watering during active growth in spring and fall. Prune lightly to encourage branching. No fertilizer needed.
Pre-flowering
2-4 weeksLeaf nodes thicken and color intensifies to deep red; flower buds begin forming within foliage clusters.
Reduce watering slightly. Cooler temperatures (50-65°F nights) trigger intense red coloration and flowering. Provide maximum sunlight.
Flowering
8-16 weeks (peak November-March)Distinctive red cone-like inflorescences emerge, often with yellow tips. Peak color and bloom occurs fall through early spring.
Minimal watering. Do not fertilize. Harvest flowers if desired for arrangements. Flowers last 4-6 weeks on plant.
Post-flowering
4-6 monthsSpent flower heads remain ornamental on plant; foliage color may fade slightly as temperatures warm; plant prepares for dormancy.
Water sparingly. Remove old flower heads if desired for neater appearance, though they provide winter structure. Minimal supplemental watering.
