Angelonia, also known as summer snapdragon, is a beautiful flowering plant that is commonly grown as an annual in most climates. However, in USDA hardiness zones 9 to 11, where the winters are milder, angelonia can be considered a tender perennial. This means that it has the potential to come back year after year if it is protected from frost.
In my personal experience as a gardening and landscaping expert, I have seen angelonia thrive as a perennial in these zones. When provided with the right care and protection, angelonia can survive the winter and regrow in the following spring. However, it’s important to note that even in these zones, angelonia may suffer some damage or die back during particularly cold winters.
To give angelonia the best chance of coming back every year, it is important to provide it with the right growing conditions. Angelonia prefers full sun and well-draining soil. It is also important to water the plant consistently, keeping the soil evenly moist but not waterlogged. Avoid overwatering, as this can lead to root rot and other issues.
In colder climates, where angelonia is not a perennial, it can still be enjoyed as an annual. It is a great choice for adding color and interest to flower beds, containers, and hanging baskets during the warmer months. Its upright spikes of flowers come in a variety of colors, including purple, pink, white, and blue, and can provide a lovely accent to any garden.
To keep angelonia blooming throughout the summer, regular deadheading is recommended. This involves removing the spent flowers to encourage the plant to produce more blooms. Additionally, fertilizing angelonia every 4-6 weeks with a balanced, water-soluble fertilizer can help promote healthy growth and abundant flowers.
Angelonia is typically grown as an annual in most climates. However, in USDA hardiness zones 9 to 11, it can be considered a tender perennial and has the potential to come back year after year if protected from frost. Providing it with the right growing conditions, including full sun, well-draining soil, and consistent watering, can help increase its chances of returning each year. Whether as a perennial or an annual, angelonia is a beautiful addition to any garden or landscape.
