Agapanthus are known for their large, blue drumstick-headed flowers in summer. These South African perennial plants are equally suitable for borders and large containers. Agapanthus look great when planted with drifts of ornamental grasses, sun-loving rudbeckias and goldenrod. Most agapanthus are hardy and their leaves die down in winter.
Agapanthus seeds are easy to grow, preferably sown fresh and pricked out individually next spring. With a bit of luck they should flower the following season.
Sow in a seed tray, and cover with grit. When the 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.
