How to grow agapanthus from seed

Agapanthus are easy to grow from seed and you may get flowering plants in as little as two years.

Collect seed when the seedhead is becoming brown and the capsules are starting to burst. If the weather is turning cold you can collect seed prematurely and store the whole seedhead in a paper bag, but it's preferable to let the seed ripen on the plant.

Agapanthus seed is thin, laid flat in overlapping layers in a papery capsule that bursts into three separate sections. The seed is black with a papery tail and bears a resemblance to tadpoles.

They are easy to grow, preferably sown fresh and pricked out individually next spring. With a bit of luck they should come to flower the following season.

You will need

  • Agapanthus plants
  • Seed trays
  • Seed-sowing compost
  • Sharp horticultural grit
  • Dibber
  • Modules or small pots

Extract the seeds from their pods. They should fall out easily. Sow them straight away.

When you have sown the seeds, cover the compost with sharp grit.

When seedlings have strong shoots and roots, knock them out of the tray and separate.

Pot up seedlings individually into modules or small pots.

Finish the surface of each pot with grit to retain moisture, keep down weeds and provide drainage around the crown of the plant.

If some seedlings are extra-special, select them and when they are big enough divide the plants to make more of your favourites
