Riveting, ravishing, radiant red! Get your fix of this captivating color with Stewartstonian Azalea. This isn’t the deep pink of so many so-called “red” flowers, but the real deal. Stewartstonian covers itself in luscious red blooms in mid-spring, when it’s a joy to be outside and you’re firing up the grill for another season. The blossoms also coincide with the return of the ruby-throated hummingbirds, who relish their sweet nectar. Out of bloom, Stewartstonian is still a winner. It has a dense habit and leaves that persist well into winter, making it a choice low hedge for lightly shady spaces.

Growth Facts

The Story

Joseph Gable, born in 1886, grew up on his family’s farm in Pennsylvaniajust north of the Maryland border and 40 miles from Baltimore. After returning from World War I in 1919, Gable resumed farming, but he soon lost interest in growing potatoes and hay and developed a new passion—breeding Azaleas. He threw himself into his work, developing scores of novel plants for the public to enjoy. Between 1927 and 1972, he introduced 164 fine new Azaleas. Joe Gable introduced Stewartstonian in 1952. He named it after his hometown, Stewartstown.

The Details

Fall color, too! Stewartstonian Azalea puts on a lovely second performance when the weather turns cool. Its leaves turn a rich deep burgundy, and the show lasts a long time.

How to Grow

Azaleas appreciate a little pampering. They thrive when shielded from hot summer sun and given moist but well-drained, acidic soil. They never like to dry out but don’t care for soggy conditions, either. Azaleas can “burn” from harsh chemical fertilizers, so feed with a gentle organic product like Bower & Branch Elements™ Fertilizer. Azalea lace bug can sometimes be an issue, but specimens grown in optimal conditions in most cases will remain healthy and resistant to attack. Of all the Azaleas on the market, Stewartstonian is one of the most adaptable. It can be successfully grown in many parts of the country.
