Highlights

This native, southern flower has an unforgettable shape when in bloom. Their sculptural bright-red flowers appear in the late spring into summer. The flowers turn into pea-like seed pods in the fall—the seeds are poisonous, so be careful when planting near pets or kids! Coralbean goes by many names: Cherokee Bean, Cardinal Spear, Red Cardinal, or Coral Bean (two words). No matter what you call it, these hummingbird favorites look stunning in southern gardens and require minimal care to thrive. Scroll on for care and planting tips.

Coralbean is a stunning native flower that thrives in the hot, full sun of the South. Its bright red flowers in the spring and summer are butterfly and hummingbird favorites, and its green triangular leaves look brightly verdant when not in bloom. And that’s not all the benefits of planting coralbean…

Coralbeans have evolved to have some pretty strong deterrents against being eaten.

What are the benefits of planting coralbean?

Planting native plants makes our yards and spaces gorgeous while helping the birds, butterflies, and animals (and helping save us time!) Here are three reasons why planting native is worth it:

  1. Without native plants, iconic animals like monarch butterflies and songbirds won’t have the food or homes needed to survive
  2. Native plants save time and money: after the first year of getting established, native plants are happy with rain
  3. Native plants are gorgeous! Coralbean is a perfect example of how beautiful and resilient native plants are—they are always the best choice for our gardens.

WARNING! Coralbean is not a great native plant for pets or kids

Coralbeans have evolved to have some pretty strong deterrents against being eaten. These evolutionary protections make them not great for planting near pets or kids. Warnings include:

The seeds are poisonous. After the bright red flowers come seed pods, which turn black. Inside these dark sculptures are bright red seeds that are highly toxic to humans. You can see from the picture how similar they look to candy—do not plant coralbean near children!

The plant has thorns. Similar to a rose bush, coralbean has thorns on its woody stems.
