Description

Tropical Milkweed is a tender erect perennial often grown as an annual. It can be weedy in disturbed areas and is often found naturalized in waste places, roadsides, or fields.  Bright orange-red flowers form in clusters on top of leaves and stems that have a milky juice when damaged.  Plant it in the full sun in moist, fertile, well-drained soil.  It will reach a height of 4 feet and a spread of 2 feet.

This plant is not recommended for attracting Monarch Butterflies because they can bloom out of sync with Monarch migration patterns and hold them too long in one area affecting their populations.  Plant one of the native milkweeds instead.
