About Coral tree
Erythrina numerosa, known as koralník početný, is an ornamental tree from the Fabaceae family, distinguished by its spectacular coral-red flowers that appear in winter, often before the leaves. Its thorny trunk and robust form make it ideal as a shade tree in tropical and subtropical gardens, or as a striking specimen plant for dramatic visual impact. It attracts pollinators such as birds and butterflies.

Care tips
It prefers full sun exposure for optimal flowering and well-drained soil, tolerating a variety of soil types as long as they don't retain excessive moisture. Watering should be moderate, allowing the substrate to dry out between waterings, especially once established, as it is quite drought-tolerant. Avoid overwatering, which can lead to root rot; it's better to err on the dry side than the wet side. Protect young plants from severe frosts.
