Peruviana, also known as Be-still tree, is an upright, open shrub or small tree with lance-shaped, mid- to green leaves. Produces scented apricot-yellow flowers, followed by triangular-ovoid, red, later black seed pods. In general, Thevetia is fast growing. Foliage is glossy and deep green, flowers are clusters of yellow funnel-shaped flowers. Can be used as hedges, or trained into tree form. They require full sun, heat and regular moisture, and are not very frost tolerant. This is a poisonous plant. Seeds are highly toxic if ingested.
It is necessary to prune your deciduous flowering shrub for two reasons: 1. By removing old, damaged or dead wood, you increase air flow, yielding in less disease. 2. You rejuvenate new growth which increases flower production.
Pruning deciduous shrubs can be divided into 4 groups: Those that require minimal pruning (take out only dead, diseased, damaged, or crossed branches, can be done in early spring.); spring pruning (encourages vigorous, new growth which produces summer flowers - in other words, flowers appear on new wood); summer pruning after flower (after flowering, cut back shoots, and take out some of the old growth, down to the ground); suckering habit pruning (flowers appear on wood from previous year. Cut back flowered stems by 1/2, to strong growing new shoots and remove 1/2 of the flowered stems a couple of inches from the ground) Always remove dead, damaged or diseased wood first, no matter what type of pruning you are doing.
