Heart-leaf Hibiscus, Tulipan del Monte, Tulipa de Monte, Malva Rosa del Monte
Hibiscus martianus (H. cardiophyllus)


The beautiful crimson flowers of heartleaf hibiscus begin appearing in early summer and don't stop until late fall. A small, drought- tolerant shrubby perennial native to the Rio Grande Plains, Edwards Plateau and Eastern Trans-Pecos, it is adaptable to different soil types as long as they are well-drained, rotting in heavy clay. In its native habitat it is often found growing in shade under spiny shrubs, but it can be grown in full sun as well. Periodic tip pruning will promote more blooms and compact growth. It unfortunately is not reliably cold-hardy in temperatures below 20 degrees F., although it may be root hardy as far north as Austin in mild winters or in the right microclimate. But its prolific, beautiful red blooms that last all summer and fall make it worth re-planting every year farther north.
