Palms and Cycads Jatropha A zebra longwing butterfly on the bright red flowers of a jatropha shrub in the butterfly rainforest at the Florida Museum of Natural History. Jatropha is an evergreen shrub or small tree with stunning flowers that will bring butterflies and hummingbirds to your garden. There are two species of Jatropha that grow quite well in South and Central Florida, Jatropha integerrima and Jatropha multifidi. Characteristics It should be noted that all parts of Jatropha are poisonous when ingested, so take care if you have children or pets frequenting your landscape.

Jatropha is a tropical evergreen that has slender stems and multiple trunks. These plants can reach about 15 feet tall and have an equal spread when left unpruned. Jatropha integerrima is native to Cuba and the West Indies and is sometimes called peregrina, spicy Jatropha, or fire-cracker. The individual flowers on this species are star-shaped and generally red, although a pink-flowered variety exists. Flowers are 1-inch wide and are produced year-round in beautiful clusters that are held upright above the lobed leaves.

Some of the butterflies you may see enjoying this plant include monarchs, swallowtails, and zebra longwings. Jatropha multifida, commonly called coral plant, is native to Mexico. This species has flat circles of coral-pink flowers and distinctly tropical-looking foliage that is deeply dissected and fan shaped. Coral plant is a bit more cold tender than peregrina. While these two species are not a problem in our state, there are some Jatropha species that are invasive in Florida.

You may have heard of J. Planting and Care Once established, J. Jatropha plants need well-drained soil, and while they can handle partial shade to full sun, they will flower best in areas with full sun. This plant is not salt tolerant.

Jatropha grows best in zones 10 to They are marginal in zone 9B; frosts and freezes will damage them, but they usually recover quickly. Jatropha tolerate pruning well, which gives you options when it comes to the form of your plant.

You can let it grow naturally into an interesting multi-trunked tree, or with some pruning, it can be trained into a fabulous espalier, shrub, or single-trunked tree. Take care when pruning Jatropha plants, as the milky sap can irritate sensitive skin. The versatility of these plants is not limited to your pruning skills—Jatropha can actually work quite well in a large container on a porch or patio.

You can see why Jatropha multifida is often called coral plant.



Botanical features[ edit ] Leaves : The leaves have significant variability in their morphology. In general, the leaves are green to pale green, alternate to subopposite, and three- to five-lobed with a spiral phyllotaxis. Plants occasionally present hermaphroditic flowers. Most fruit production is concentrated from midsummer to late fall with variations in production peaks where some plants have two or three harvests and some produce continuously through the season. In addition, the seeds contain other chemical compounds, such as saccharose , raffinose , stachyose , glucose , fructose , galactose , and protein. The oil is largely made up of oleic and linoleic acids.
