The AngelMist series is bred to withstand heat and humidity. Its vigor offers stress tolerance in extreme conditions. AngelMist angelonia are bred to attract butterflies with their bold colors and scented foliage. Blooming from late spring through summer, these varieties reach approximately 4-6 inches tall and spread 12-14 inches.
During propagation, choose a well-drained medium with an EC of 0.75-0.80 and a pH of 5.5-5.8. Soil temperature should be maintained at 68-74° F until roots are visible. To encourage branching and reduce stem stretch, AngelMist angelonia should be propagated under as high a light as possible. Begin fertilization with 75- to 100-ppm nitrogen when roots become visible. Increase to 150- to 200-ppm nitrogen as roots develop.
Growing on, use a light, well-drained soil-less medium with a pH of 5.5-6.2. Maintain temperature at 75-85° F days and 62-70° F nights. Keep light levels as high as possible. The ideal range is 6,000-10,000 foot-candles. Use constant feed at 150-200 ppm, with additional iron as needed.
A single pinch is recommended when growing AngelMist varieties in 41/2- to 5-inch containers. The first pinch should be five to seven days after transplanting. Growers may pinch plants in larger, 5- to 8-inch containers a second time (14 to 21 days after the first pinch) to enhance branching and the number of flower spikes.from Ball FloraPlant
