Description

Algerian Iris is a purple-flowering bulb native to northern Africa and the western Mediterranean region.  While it will grow in the sun, this blub is particularly attractive in shady areas.   Its flowers appear in late winter and provide a much needed pop of color in the landscape.  Consider mass planting it in border fronts, along walkways or near patios where the long lasting blooms can be enjoyed.

 

Insect, Diseases, and Other Plant Problems: Grey molds, bacterial soft rot, or a virus may occur.
