Chitalpa Tashkentensis: Flowering Begins In May And Runs Until Frost
Chitalpa tashkentensis, or it is more commonly called Chitalpa is a wonderful tree for your landscape or for your garden. For one thing, it is more tolerant of poorly drained soils than desert willow, and it produces gorgeous larger, orchid-like flowers. It starts flowering in May or June and the bloom period runs until frost, unlike the once-in-the-spring-flowering Catalpa. Chitalpa flowers are borne in large clusters, each containing 15 to 40 inch long florets that attract butterflies, bees, and hummingbirds.
Chitalpa is a rapid-growing, deciduous tree that typically grows to 20 to 25 feet tall with a dense, spreading, oval crown. Lanceolate leaves (reach a length of 6 inches) are dull green on the above surface, fuzzy underneath, and taper at both ends. Bell-shaped, pink to white, catalpa-like flowers (to 1 ich across) bloom in upright racemes (15 to 40 flowers per raceme) at the branch ends starting in summer and running into the fall. Popular cultivars include ‘Pink Dawn’ (pink flowers) and ‘Morning Cloud’ (pale pink to white flowers).
Chitalpa tashkentensis is a sun loving, fast-growing, multi or standard-trunked, deciduous tree that needs only occasional watering once it is established; Chitalpa is drought tolerant. The multi-trunked tree branches out near the base and creates a beautiful oval shaped canopy. You will discover that the standard-trunked trees also have an oval shape to them. They both have an open limb structure, allowing filtered sun to pass through so other plants can grow underneath.
How To Make Chitalpa Tashkentensis Thrive
Chitalpa needs to be grown in deep, moderately fertile, medium moisture, well-drained soils in full sun to part shade; if you want the best flowers you need to plant in full sun. Chitalpa can thrive in sandy soils. Once you have established a good root system this small tree is drought tolerant, but flowering will be improved with occasional summer watering. Little pruning is required other than removing dead, broken, or poorly formed branches.

Pests and Diseases
There are no serious insect or disease problems. Powdery mildew can be a significant problem in growing areas with high summer humidity (predominately this occurs in the southeastern U.S.) and in growing conditions where trees are planted in too much shade. Additional disease problems can include verticillium wilt, root rot, and leaf spots. You should be on watch for aphids, mealybugs, scale and whiteflies.
Trees may sucker at the base. Propagate by cuttings. This hybrid will not produce viable seed.
