  • circleLife cycle

    Agapanthus 'Johanna', commonly known as Lily of the Nile, begins its life cycle with seed germination, which occurs in warm, moist soil conditions. The seeds develop into small seedlings with initial leaves and a root system. As the plant matures, it forms a clump of strap-like leaves and establishes a robust root network. Vegetative growth continues with the leaves elongating, and the plant eventually produces tall flower stalks topped with rounded clusters of blue or purple flowers in summer. After flowering, seed pods may form, which burst open when dry, releasing seeds that can propagate new plants. Finally, Agapanthus 'Johanna' may enter a period of dormancy during colder months, especially in cooler climates, before resuming growth when the conditions become favorable again.

    • Propogation time

      Spring-Early Summer

    • Propogation: Agapanthus 'Johanna', commonly known as Lily of the Nile, is most effectively propagated through division, which should take place after the flowering season has ended, usually during the fall. To propagate by division, carefully lift the clump out of the ground with a shovel and gently separate the rhizomes, ensuring that each division has at least one fan of leaves and a portion of roots. Replant the divisions immediately, maintaining the same planting depth as before, which typically means the crown should be about 1-2 inches (2.5-5 cm) below the surface. Water the newly planted divisions thoroughly to help establish them. This method of division allows for the rapid increase of plants and is often preferred for its simplicity and effectiveness.
