Plant in late spring after all danger of frost is past.
Where to plant
Grow on a site that receives at least 6 hours of direct sunlight in a container or the landscape.
How to plant
Work a 2- to 3-inch layer of compost or other rich organic matter into planting beds, or use a high-quality potting soil for containers. Make sure soil is loose and well-draining. Tease out any pot-bound roots to encourage healthy plant development. Dig a hole the size of the root ball and place the plant so the top of the root ball is level with the surrounding soil. Fill in the hole with soil, tamp down gently to remove air pockets, and water thoroughly.
How to grow from seed
Sow seeds indoors 6 to 8 weeks before your last frost date. Lightly press seeds into a sterile seed-starting mix. Angelonia seeds need light to germinate, so don’t cover them. Keep the soil surface evenly moist and don’t allow it to dry out. Seeds need temperatures of 70 to 75 degrees to germinate, so use a heat mat if necessary. Seedlings emerge in 10 to 14 days. When all danger of frost is past, gradually acclimate plants outside before transplanting into the garden. For direct sowing outdoors, wait until all chance of frost is past.
