Shrubs have many uses in the garden, from filling in a bare area with greenery to acting as a privacy hedge or screen. Flowering shrubs are especially lovely to have in the garden, offering a little extra color. There are a number of shrubs and bushes that produce striking blooms.
Woolly butterflybush (Buddleia marrubifolia) is a flowering shrub that bursts into bloom in early spring, producing small orange flowers that last until early autumn. The shrub is commonly used as a border or container plant in USDA zones 6A to 10A. Woolly butterfly bush is best cultivated in full sunlight, though the plant does not care much about soil pH: acidic, alkaline or neutral soil all works for this plant. Woolly butterfly bush should be watered frequently---enough to keep the soil moist to the touch. The shrub is an excellent addition to butterfly gardens, as its common name suggests. Woolly butterfly bush also looks lovely alone as a specimen plant.
A member of the meadow beauty family, princess flower (Tibouchina urvilleana)---also called glory flower---is a flowering evergreen shrub native to Brazil. The plant has a round habit, with long green leaves and floppy, bright purple flowers. The plant is often cultivated as a specimen plant in USDA zones 8 to 12. Ideally, princess flower should be planted in a rich, fertile and well draining soil in full sunlight with a little afternoon shade. The plant can tolerate other soil types if properly mulched. Princess flower will do best with regular watering, but take care not to overwater, as that may damage the shrub's roots.
A member of the leadwort family, plumbago (Plumbago auriculata)---also called sky flower---is an evergreen shrub native to South Africa. Plumbago boasts bright green leaves and clusters of pure blue flowers. Plenty of sunlight is crucial to the plant's health, so be sure to plant plumbago in full sunlight in USDA zones 8B to 11. The ideal soil for this plant is a sandy, well-drained soil that is slightly acidic. Plumbago is fairly drought tolerant and needs little to no supplemental watering. The butterfly attracting shrub is often cultivated as a border plant. Plumbago also responds well to pruning.
