New to many greenhouse shelves, angelonia (or summer snapdragon) is a spectacular addition for continuous color in any garden. Having only been around since the late 1990s, there are several fresh additions to choose from in this plant's playbook. A tough perennial, angelonia stands up against summer's heat and humidity with no problem, making it a hearty and colorful addition to any sunny spot.
There are a variety of angelonia selections to choose from. Some series boast the largest bloom size, while others offer dwarf plants (perfect for container culture). One of the more recent developments in angelonia breeding are seed-grown varieties. This option helps to lower production cost and offers quality plants at inexpensive prices, as well as a good variety of color options.
One of the most acclaimed series of angelonia is Serena. Serena Purple angelonia keeps gardens looking colorful all summer long. Serena flowers have an extensive blooming season and are dependable and hardy, even in blazing summer temperatures.
Angelonia Care Must-Knows
Angelonia structure, or habit, is rather versatile. Most plants grow upright with spires of flowers and deep green, glossy foliage. The height range is usually between 1 to 2 feet, which makes these plants a great addition to mixed containers (especially since angelonia won't outcompete its neighbors).
Besides upright, there are also angelonia plants that grow more horizontally instead of vertically. These varieties generally won't grow more than 1 foot tall but they spread out nicely to fill a garden. If you're looking for a cascading trailer, angelonia may not be the best fit. This particular trailing type doesn't readily spill over the edges of containers or walls; instead, it grows straight out. Try growing angelonia in a sunny window box.
When planting angelonia, look for sunny spots with lots of airflow. Keep in mind that this plant won't produce many flowers and is more disease-prone when situated in the shade. And don't worry about too much sun or heat; angelonia are fairly drought tolerant and have no problem with hot summer days.
If you look closely at the summer snapdragon flowers, you'll see how this plant got its nickname: Blooms are reminiscent of the wide-open mouth of a monstrous dragon. But, unlike true snapdragons, angelonia flowers present as one fused petal with no hinges. The vibrant flowers tend to appear in the blue/purple to white spectrum. Recently, a few red varieties have popped up, as well.
Good news: Angelonia seeds produce flowers all summer long, and the flower doesn't require any deadheading to keep blooms going.
