Chaya (Cnidoscolus chayamansa) is nicknamed tree spinach but that’s kind of like calling iceberg lettuce spinach. Chaya contains more than twice as much protein, calcium, Vitamin C, iron, fiber and caronteniods as spinach, according to a USDA report published through Purdue University.
It’s also much easier to grow. It’s a dietary staple on the semi-arid Yucatan Penninsula but also thrives in Florida’s hot, rainy summers.
Like many tropical plants (including spinach to a lesser degree), chaya contains hydrocyanic glucosides in its leaves. Cooking the leaves inactivates the toxic compound.
In colder climates they grow well in a sunny window, although you'll want to put it outside once temperatures are consistently above freezing. They've consistently come back from the ground with temperatures as low as the mid-20s but they're among the first plants to lose their leaves when it gets near 30 degrees.
Due to changes in government regulations, we can no longer ship living plants overseas, or to Hawaii or Puerto Rico. |
