The Story

Plant Bio

Erythrina herbacea, commonly known as Coralbean, is a deciduous shrub or herbaceous perennial. It features striking, tubular red flowers on tall spikes that often appear before the leaves. The foliage consists of trifoliate, arrowhead-shaped leaflets. This species is notable for its ability to die back to the ground in winter and resprout from its roots in spring. Its vibrant flowers are a major attractant for hummingbirds. The bright red seeds, while ornamental, are highly poisonous.

Uses & Benefits:

The vibrant red flowers add striking color to gardens and attract hummingbirds.

Drought-tolerant once established, reducing water needs.

Provides food and habitat for local birds and pollinators.

Common Questions

Coralbean questions

What zones can Coralbean grow in?

Coralbean is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Coralbean deer resistant?

Yes — Coralbean is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Coralbean bloom?

Coralbean typically blooms in spring to summer through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Coralbean need full sun?

Coralbean does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Coralbean drought tolerant?

Yes — once established (usually after the first full season), Coralbean handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
