One of the most versatile plants around and a great plant for beginning gardeners. This African native can tolerate virtually any soil conditions from drought to moist soil found at the water’s edge. Requires little maintenance to maintain a neat appearance. Just remove faded flowers to keep plant looking fresh. The spiky foliage adds great texture and interest to formal settings or plants can be naturalized for a casual, carefree look. Blooms last only a day or two but are produced over a long season through the spring and summer.

Prepare the garden by breaking up the existing soil (use a hoe, spade, or power tiller) to a depth of 12-16” (30-40cm). Add organic matter such as manure, peat moss or garden compost until the soil is loose and easy to work. Organic ingredients improve drainage, add nutrients, and encourage earthworms and other organisms that help keep soil healthy. Give plants an extra boost by adding a granulated starter fertilizer or all-purpose feed that encourages blooming (for example fertilizers labeled 5-10-5).
