Chitalpa tasketiensis is a hybrid, created in the sixties by crossing catalpa bignonioides with chilopsis linearis; the result is a small tree, or even a large shrub, with deciduous leaves and very rapid growth, which tolerates winter cold and summer drought well. The adult specimens can reach 8-9 meters in height, over a period of about ten years; the stem is erect, often consisting of multiple trunks. The foliage is broad, rounded, quite dense. The foliage is oval in shape, lanceolate, of an apologetic green color, slightly coriaceous and waxy; tends to fall in a narrow period of time, in winter. From late spring to autumn it produces large bunches made up of large pink trumpet flowers, very showy. The abundant and prolonged flowering and the fairly contained dimensions make this tree very suitable for cultivation in the garden, even as a shading tree. The cultivation for ornamental purposes for now seems widespread mainly in North America, while in Europe this tree is still considered "exotic" despite its European origin.
Chitalpa tasketiensis trees prefer bright and sunny locations, although they can stand a few hours of light shade a day. They are resistant specimens, they do not fear the cold and generally tolerate snowfalls and winter frosts well. They also sustain wind and environmental pollution without problems.
Chitalpa tasketiensis plants which have been settling for a long time are satisfied with the rains, but it is good to water the young plants during the drier seasons; in principle, however, chitalpe have inherited drought resistance from chilopsis. For good flowering during the summer months it is advisable to water occasionally. During the fall, bury a mature organic fertilizer at the base of the plant.
Check that at the base of the plant water does not form, which could be dangerous for the health of the plant.
The plants of Chitalpa tashkentensis prefer sandy soils, very well drained, not particularly rich in organic matter. They can generally adapt to any type of soil, as long as they are well drained and not too compact.
To get the maximum development it is recommended to bury the plant in a soil mixed with sand, so as to make it lighter and more draining.
The multiplication of this genus of plants generally occurs by semi-woody cutting, in summer; in spring it is possible to sow the seeds of the previous year, or you can practice sowing in autumn or late summer; young plants should be grown in pots up to a height of 25-45 cm before being planted to allow them to acquire the necessary strength to be transplanted.
Chitalpa tasketiensis: Pests and diseases
It is a very resistant tree variety, which is generally not attacked by pests or diseases. For safety, before flowering, it is possible to intervene with specific products that are pesticides and fungicides, so as to preserve even the weakest specimens from possible diseases.
