Shrub of the Month – September

SEPTEMBER 2018 – SUITABLE SHRUBS FOR HOWTH
This selection of shrubs is chosen specifically for the poor, thin, acid soils common on the upper parts of the Howth Penninsula. The two we have selected below are at their best this month.

Clematis tangutica

A species clematis that needs plenty of room. In late summer, the stems are decked with dangling yellow lantern like flowers, and as the first ones go over they are replaced by large, fluffy, white seed-heads. By late summer both flowers and seed-heads are present on the plant at the same time, which doubles the effect. As with all the late-flowering clematis, pruning is easy. Simply cut back the stems to a pair of strong buds 15-20cm (6-8in) above ground level before growth begins in early spring. This pruning technique makes late-flowering clematis useful for training into shrubs, trees and climbing roses as the clematis growth is removed each spring and so never becomes too much of a burden on its supporting plant.

Indigophora geradiana

Indigofera Gerardiana grows between 3 feet high and 3 feet spread or 0.9 x 0.9 metres.

This flowering or fruiting shrub produces flowers in Summer

If you have a hot and dry area (eg South and West facing) protected from rain this is an excellent shrub to use in such a garden environment. Deciduous and loses leaves in Winter Hardy and will tolerate frost unless very severe

Plant like this enjoy humus or organic rich soil. The organic matter not only feeds the flowers and leaves but also retains moisture for the plant. Garden plants like this one are pruned to create interesting plant shapes to act as specimen.
