Angelonia salicariaefolia, commonly known as Violet-flowered Angelonia, is a small shrub that grows between two and five feet tall. It is known for its fragrant, white to off-white blooms, which turn to blues, lavenders, and purples as they mature. It is a full sun to semi-shade loving plant, and needs regular or moderate water depending upon the climate. It can be grown year round in USDA Zones 9-11, with mature plants being cold hardy at least down to the 30s F for a short duration of time.
When it grows in pots, Angelonia needs to be taken care of in cold regions. To establish a healthy plant in the pot, plant it in a well-draining soil mix and place it in a sunny or a partially shaded spot. Make sure it is shielded from heavy winds too. Water it gently and regularly to keep the soil moist. Plants in brittle winter areas additionally need to be covered with a thick layer of organic mulch in late fall, to stay warm through the winter season. Use cold-frame protection when temperatures dip below t 30sF for extended periods.
