There are three zones where Angelonia can be grown as a perennial: Zone 8, Zone 9, and Zone 11. It is either grown as an annual or brought indoors for the winter months. The plants can withstand temperatures as low as 30°F (-1.1°C).
The annual bedding plant Angelonia can be used on the border of a garden or in large groups to create an eye-catching display. It’s also possible to grow them in pots or window boxes. Cut flowers keep their fragrance indoors, and the foliage does as well.
Perennial Angelonia (zone 8–11) is a slender, 2-3-inch-long plant with smooth stems and narrow, pointed leaves. According to some, the foliage has a pungent odor, like apple pie. Almost an inch across, the flowers are borne on slender, upright spikes that can grow up to 8 inches long. From May to October, North Texas has a long blooming season, when the flowers are at their peak – a 4-6 week period for temperate climates and longer for zones 8-11. In terms of height and spread, Angelonia can grow up to 18 inches tall, with a spread of about 12 inches. It has soft (not woody) stems and a bushy habit.

Does Angelonia Come Back Every Year?
Yes. Angelonia returns each year and will mature into a new plant every season, given sufficient care and attention – meaning that it must get direct sunlight during the summer and other parts of the growing season (including winter).

Angelonia Bloom Cycle
In the late spring and early fall, angelonia flowers come into bloom. They add cheery color to pots, borders, or flowerbeds. During these months, you need to provide sufficient water and care so that the plants can remain healthy. Suppose watering is discontinued at this time of year without any fertilizer or nutrients in their system (allowed because Angelonia flowers are not active). In that case, most angelonias will eventually cease flowering altogether. In the fall and winter, you may notice that it gradually dies back. Things go downhill from here as many plants will drop their leaves in addition to losing their flowers due to extreme dryness during these months (again, because they don’t get enough water).
To What Extent Do Angelonia Flowers Last?

Angelonia plants die if they are left outside in freezing temperatures, and they don’t return the following year. Zones 9–11. Perennial plants can be left outside all year, but they should not be fertilized in the winter.
