A number of people are allergic to the Desert Mallow, for this reason it is often called "Hierba Muy Mala" in Spanish. There are over 10 different species of Sphaeralcea in the Southwest with varying flower color and leaf shape.
Although it is a desert plant, the desert mallows grow better in a fertile soil. Provided that he soil is well drained, it needs regular water the first year, particularly if it has not been planted in the fall. Planting it in the fall allows it to grow its root system before the punishing heat of Phoenix summer.
The coral flowers of the desert mallow come in summer to fall. They are mallow like with 5 petals.
