The long bloom season and ability to thrive in filtered shade are two of the many reasons Mexican honeysuckle is a highly desired plant in the drought-tolerant landscape.

Plant in well-drained soil — a mixture of native soil mixed with compost at a ratio of 1:1. In late winter, prune back any frost-damaged growth in zones 8 and 9. Lightly prune in early spring to promote more compact growth, but avoid pruning more than half of the shrub at a time.

Mexican honeysuckle does best when planted in dappled shade but can handle full sun, although the plants will be somewhat smaller in sunny spots.
