I did not have good success growing Angelonia from seed my first year, but I will try again because, once established, Angelonia is an excellent annual for containers. I struggled with germination, although the seedlings that did germinate grew well. In the pots, Angelonia did not bloom or bulk up, but I suspect I overcrowded all my containers that first year. So lessons learned which is what gardening is all about.
This is my personal growing guide. I use it to track seed sources, when to start seeds and if I should adjust growing conditions in my own greenhouse and garden. Please don’t consider this professional grower’s advice. I like the information cards from Ball Seed – here is Serena Angelonia.
FAVOURITE VARIETIES AND SOURCES
- Serena Rose
- Serena Blue
- Serena Purple
|40°F or 4°C, heat and humidity tolerant
|Deer and rabbit resistant
|Bloom time & length
|Late spring to late summer, filler thriller
|Not needed, continuous blooming, can shear
|Medium to average, don’t allow to dry out
|Slow-release fertilizer, light feeder
My own notes: don’t overcrowd with mixed planters. This will impact growth and blooms.
Sow seeds 6-8 weeks before frost. Angelonia should not be planted out until warm weather is assured, generally 2 to 3 weeks after the last frost.
- 10 weeks before planting out is Mar 18
- pelleted seed on the soil surface – do not cover
- As pellet disintegrates, seed needs light to germinate
- 74°F/23°C for 4-5 days – use heat mat – warm water
- 68-80°F/20-26°C days and 64-66°F/18-19°C nights
- 4-4.5 in/10-11 cm pots
- transplant when weather warms, 2-3 weeks after frost (May 27)
- pinch young plants to encourage branching, no pinching once established
- does not need deadheading
