Angelonia Plant In Winter. When placed in an area that receives bright direct light and watered once per week the plants will survive the winter. They need to be shifted indoors during winter.
The plant will typically behave as a perennial in Florida unless exposed to a cold winter. This winter I may leave some other things in there as well including the Angelonia. They make good cut flowers and the foliage retains its fragrance indoors.
Angelonia can maintain its flowering even throughout winter when kept indoors at a warm and sunny spot.
Angelonia is a charming but tough-as-nails summer annual. Use a commercial potting soil which will provide the right acidity and drainage. A plant like Angelonia is hardy in zones 9 thru 11 and even covering and mulching will not be enough for the plants to survive. The plant grows around 12-18 inches in height with a spread of about 12 inches.
