Erythrina crista-galli aka Cockspur Coraltree

Erythrina crista-galli, also known as the cockspur coral tree, is a small flowering tree in the Fabaceae family. It is native to Argentina, Uruguay, southern Brazil, and Paraguay, but is widely planted as a street or garden tree in other countries, such as California. The ceibo, corticeira, seíbo, and bucaré are some of the common names for this species within South America. Its specific epithet, crista-galli, means "cock's comb" in Latin. This tree is characteristically found in gallery forest ecosystems along watercourses, as well as in swamps and wetlands. In urban settings, it is often planted in parks for its bright red flowers. The ceibo is the national tree of Argentina, and its flower is the national flower of Argentina and Uruguay. The cockspur coral tree is a small tree with a woody trunk and irregular, spiny branches. The girth of its trunk measures 50 cm (20 in), and it typically grows 5-8 m (16-26 ft) tall, although some individuals can grow up to 10 m (33 ft). The root is a taproot with nodules produced by nitrogen-fixing bacteria, which facilitate the tree's absorption of nitrogen in return for organic substances that the bacteria need. The branches form a layer without definite form and die after flowering. While the cockspur coral tree is invasive in eastern Australia, it is a super rare houseplant that is easy to grow and needs regular watering to thrive. It does best in long-lasting, direct light and should be less than 1 foot from a window. The plant likes soil that is well-draining, and shouldn't need added fertilizers if you repot each time it doubles in size. The cockspur coral tree belongs to the Erythrina genus and is native to Central South America.
