Propagation of Deciduous Agapanthus

Deciduous Agapanthus plants are currently being cleared to tidy up the surface of pots. Stems with seed heads can be cut to place out and dry in a cool area such as a shed or utility area.

Seeds may not come true to type but could still yield some interesting variations.

After a 4-6 week drying off period I take two options.

Option 1

  • Package the Agapanthus seeds in envelopes to store in a cool environment during the winter months.
  • Sow seeds in spring into modules of seed compost.
  • Cover seed with perlite or vermiculite.
  • Grow on under glass at an average temperature of 15 degrees centigrade. This may need to be sustained at night with a small fan heater during this early stage of the year.
  • Over-winter the young plants in a cool glasshouse area for protection. I cover with a layer of fleece on extra cold nights.
  • Plants will take about 3 years to produce the first significant flowers.

Option 2

  • Sow seeds now as with option 1. This gets the process ahead by 4 months for advanced growth next year.
