Angelonias have been one of the top herbaceous ornamental plants for the past 10 years. Yet, many gardeners may not be familiar with these colorful plants, according to LSU AgCenter horticulturist Dr. Allen Owings.
Angelonias also are called by their common name, "summer snapdragons." They can be planted throughout the summer, although April and May are the typical planting times.
"These are tough plants," Owings says, noting that they have a good drought tolerance once established and are promoted as withstanding temperatures down to 25-30 degrees F. They can take winter growing conditions in hardiness zones 8B and south.
In the Baton Rouge, Lake Charles, New Orleans and Lafayette areas, angelonias come back after mild or slightly warmer-than-normal winters, especially if located in well-drained beds in a slightly protected area of the landscape. In central and north Louisiana, Owings says, they are probably best treated as annuals.
Select a full-sun location with adequately drained soil. Use a slow-release fertilizer at planting. Expect plants to begin flowering shortly after being added to the landscape – flowering will continue until the first killing frost if conditions and cultural practices are correct.
One of the older varieties of angelonia is Hilo Princess. New varieties include the Angelface series from Proven Winners and the AngelMist series from Ball FloraPlant. All of these varieties are vegetatively propagated by stem cuttings. The newest angelonias are the Serena series, which are seed-propagated.
Varieties in these series come in many flower colors – purple stripe, deep plum, white, purple, orchid, lavender stripe, lavender, light pink and others. The newer varieties also offer more height options. You can select plants that are taller, intermediates or now the "basket" or ground cover kinds. Typical angelonias, however, reach heights of 18-24 inches with flower spikes extending slightly above the top of the plant canopy.
"Angelonias make a great addition to a ‘cottage garden’ style of flower bed," Owings says, adding, "You can be assured that angelonias will be good performers and give you some ‘snapdragons’ in your landscape during the hot summer months."
