Louis Hamilton Desert Mallow (Sphaeralcea ambigua 'Louis Hamilton') is an evergreen perennial with gorgeous, glowing red flowers that bloom almost non-stop. This is a fast growing heat-loving perennial with fuzzy gray-green foliage.

This mallow takes little additional water in summer and tolerates almost any soil type, but prefers well-drained soils. It's best to cut it back hard after flowering to encourage fresh growth and a fuller appearance. It works well on slopes and makes an excellent specimen plant for any desert-themed garden, with blooms that attract butterflies and bees..
