Maintain consistent watering schedule. Reduce frequency as flowering approaches. Light pruning after bloom to maintain shape.
Flowering

Fun Facts
- 🌱 Leucadendron flowers are actually composed of colorful bracts (modified leaves) surrounding the true flowers, which are much smaller and located within the cone structure. This makes the 'flower head' technically a capitulum similar to a sunflower.
- 🌱 Deep Red Leucadendron evolved in fire-prone South African fynbos ecosystems and requires occasional heat stress to bloom prolifically; in cooler climates, flowering may be sparse until plants experience at least one season of hot weather.
- 🌱 The name 'Leucadendron' comes from Greek words meaning 'white tree,' referring to the silvery appearance of many species' foliage, though Deep Red is notable for its burgundy bracts and darker needle-like leaves.
