Tree Koelreuteria paniculata [Goldenraintree] Colorful small tree in bloom and interesting for its form. Tolerates heat, drought, wind, alkaline soils, and air pollution.

However, it can be too coarse for the landscape when not in bloom.

Plants bloom on old wood so hard prunings will result in loss of bloom, but will improve the…

During the fall, its soft, blueish-green needle-like leaves turn a rich, golden color. This tree does best…
Shrub Lavandula angustifolia [Common Lavender] Beautiful, fragrant purple flowers and foliage. Great plant for fine texture in the front landscape borders. Pruning to the ground every 3 to 4 years keeps the foliage full to the ground and produces uniform, fresh new growth.
