Planting earlier will give them time to get settled and bloom from late spring through fall. If you’re planting through seeds you can start the propagation process indoors in the frost with a heat mat and other growing conditions.

Where to Plant

How to propagate angelonia plant

  • Loose ground soil about 10 to 15 inches with a shovel or grab hook. 
  • Dig a hole similar to the size of the root ball, and fill one-third of the hole with compost or other organic matter.
  • Place the plant even on the soil surface. Do not plant too deep, just make the plant stand and cover its root balls.
  • Fill the soil gently to remove air pockets, water thoroughly, and make sure the plant receives good drainage and full sun.

How to grow from stem cuttings indoors:

  • Angelonia plants can easily propagate from stem cutting indoors. 
  • Take the stem cutting with no bloom and strip all leaves except the top pair of leaves. Stem cutting with no roots does not support many leaves.
  • Cut the bottom tip of the cutting to visible its fresh white-green tissue. Do not plant stem cutting with a dark spot, it might not grow properly.
  • Dip the bottom tip into the rooting hormone and insert the cutting in well-drained potting soil.
  • Use a medium-sized pot that has an adequate drainage hole. 
  • Place the pot in the shade till it gets five to six inches taller. This sign shows the cutting starts growing roots and now regular sunlight.
