Plant Type: Tree

Large growing tree type crape myrtle to 20’+ tall with a wide spreading crown. Reliable soft, luminous purple large trusses of flowers begin on average the first week of August in the city and repeat bloom until October. Fast growing shade tree that can achieve 3′-5′ a year when young in optimal conditions. Free blooming tree that displays glossy, muscular tan trunks when the bark sheds in mid-summer. These contrast greatly with the deep green foliage and sumptuous purple blooms. Long lived, cold hardy, disease resistant cultivar that has shown its merits for many decades in the southern U.S. but less often grown in our region. Fall color is bright red/ orange/ yellow. Mildew resistant- good air circulation- proper cultivation eliminates this threat. As with all purple flowered crape myrtles the flowers can fade a bit after opening. When a non-fading purple crape myrtle becomes available we will be the first to let you know. Otherwise this is a great, dependable, garden tree. Deep, infrequent, summer irrigation. Six or more hours of hot sun per day. Long lived and cold hardy cultivar.

Red is an exciting and sought after flower color for Crape myrtles in our climate. Most varieties with reliable early bloom tend toward pink, white, and lavender. Enter this Carl Whitcomb hybrid with among the truest red flowers of any Lagerstroemia cultivar. Mr. Whitcomb is an Oklahoman Crape myrtle breeder and his visceral reaction to this seedling in the field was to exclaim “Dynamite” referring to the clear red flowers. He kept the name and this has become one of the most successful red flowered cultivars in the United States. In our climate it is a reliable bloomer if sited well and consistently irrigated. Although, I have noticed very good drought tolerance with this cultivar and indeed Carl Whitcomb  plants his seedlings out in a field and then lets nature take its course- no supplemental irrigation. This is in NE Oklahoma a somewhat brutal climate. This predisposed his selections to low water requirements. He also selected it for good tolerance to powdery mildew. Best in a warm spot in full sun with rich to average soil with regular irrigation. Fast growing tree to 20′ tall and 10′ wide in time. Bloom begins in mid-August most years and diligent water will assist in flower set. Flowers are showy until early October. It has been used as a street tree in Portland with mixed success. Unfortunately, it was grafted. (grafted crape myrtles are not a good way to go) Very good with water and spectacular in summers that are warmer than normal. Brilliant true, stop sign red flowers are incredibly showy with an exotic flair. Very few hardy trees can match the color and opulence of its bloom. New growth is deep maroon changing to mid green at maturity. Wonderful tree. Fall color is brilliant orange/red and the bark exfoliates generously to reveal light tan trunks.   Unauthorized propagation prohibited. Plant patent #10,296.

Wonderful release from the National Arboretum and this three hybrid small tree is also one of the most reliable red flowering varieties. To 11′ tall forming a very rounded tree about 3/4 as wide.  Large, vivid trusses of strawberry red flowers appear in early August and are wildly showy for weeks into early autumn. Moderately fast growing (2′-3′ per year when young) to its ultimate size. Full, all day sun in a hot position. Appreciates rich soil and also loves clay soil. Consistent deep irrigation from late spring into summer spurs more reliable bloom. The brilliant flower color is showy from quite a distance. In time the bark exfoliates in patches to shades of pink and light brown. Fall color is orange/yellow/ light red and reliable. Excellent small tree for warm urban gardens. Once bloom commences it proceeds unabated for months. Disease resistant. Excellent for the hottest locations.  This tree blooms quickly in a pot and thus is slower to bulk up than other varieties. Don’t let that deter you. In the ground it grows much more quickly. A Xera favorite crape myrtle. The second 3 way hybrid released by the National Arboretum. OOOOOOH, kinky.

Underused beautiful disease resistant Crape Myrtle that is free blooming with enormous pendulous trusses of pure white flowers. To 15′ tall with a somewhat weeping habit- especially in bloom. It creates a spreading crown on a small easy to grow tree for full, all day sun and regular summer water. The crystal white large flowers appear often as early as late July in hot summers and continues unabated to about the first of October. Fall color is yellow/orange and pretty. The sinuous trunks display taupe/beige glossy bark which is just as showy. Give this wide spreading small tree room to grow. Regular summer water and rich soil yields a growth rate approaching 3′ per year when young. As with almost all Crape trees it grows quickly to its ultimate size and then it slows considerably. Excellent garden tree. National arboretum selection.
