Intermediate Bearded Iris range from 16 inches to 27 inches high, with a bloom season in early spring. Although the IBs show their dwarf ancestry in early bloom season and very interesting color patterns, they are large enough that their individual stalks may be nicely branched, forming an elegant bouquet. Like Tall Bearded Iris, they can be difficult to grow in Houston’s hot, humid climate. These iris need friable, slightly alkaline soil (in a raised bed or container), careful watering, and sun. Light is very important. Sold bare root.
