Mexican Heather

Cuphea hyssopifolia

Mexican Heather Plant Features

Prized for its lacy foliage and numerous jewel-like flowers, cuphea, commonly called Mexican heather, makes an ideal container or border plant. Growing just 10 to 18 inches tall, this shrubby, tropical annual is smothered in blooms all summer long. Plus, the flowers are as attractive to butterflies as they are to you. Colors include white, violet, or red. Mix Mexican heather with other annuals or use it to line a garden path or walkway. Hardy in zones 9-11.

Mexican Heather Growing Instructions

Plant Mexican heather in a sunny or partially sunny spot with well-drained soil and feed with a slow-release granular fertilizer at planting time. Mexican heather likes to be watered whenever the surface of the soil feels dry to the touch.

This plant not intended for human or animal consumption.

Special Care

Mexican heather has a dense, compact growth habit. But, once in a while, your plants may look a bit rangy. If that happens shear the plant back by a third of its height to encourage tighter growth.
