Seedling
4-8 weeksYoung plants develop their first true leaves and establish a root system
Keep soil moist but not waterlogged; provide bright indirect light; protect from strong winds
Establishment
1-3 yearsTree grows taller with branching structure; develops woody stem; no flowers yet
Water regularly to establish deep roots; stake if necessary in windy areas; light pruning to shape
Vegetative Growth
Ongoing until flowering beginsMature foliage develops; tree reaches desired height and form; leaves compound and deciduous
Maintain watering schedule; fertilize with low-nitrogen balanced formula in spring; prune dead branches
Flowering
4-8 weeks (spring)Brilliant scarlet-red tubular flowers appear in dense clusters before leaves emerge in early spring
Flowers appear on bare branches; no special care needed; allow pollinators full access; avoid heavy pruning during flower season
Fruiting & Seed Production
3-4 months after floweringElongated bean-like pods develop and mature; pods eventually split to reveal seeds
Allow pods to remain on tree if seeds are desired; remove fallen pods to prevent self-seeding if unwanted; pods contain toxic seeds

Cultural & Ceremonial Significance
CraftIn South Africa and other regions, the Coral Tree holds cultural and ceremonial importance and appears in traditional art and symbolism as a symbol of strength and vitality. [source]

Fun Facts
- 🌱 Erythrina caffra can live for over 100 years in ideal conditions and may reach impressive sizes in mature specimens planted in parks and gardens.
- 🌱 The tree's distinctive thorny branches serve as a defensive mechanism; the thorns are prickles (modified stipules) rather than true thorns.
- 🌱 All parts of the plant contain toxic alkaloids, particularly the seeds, making it important to keep the plant away from pets and children who might consume the bean-like pods.
