They are often called by their common name lily of the nile or the African lily. The agapanthus is an ornamental clumping perennial that belongs to the Alliaceae family and is also considered to be a monocot.

Where to Plant Agapanthus

Agapanthus are best planted in full sun in southern states and coastal areas of Australia for best growth. Inland hotter climates, grow agapanthus in afternoon shade to prevent the tips of the leaves from burning.

My Agapanthus Won’t Flower reasons why?

  • If agapanthus are planted in the shaded parts of the garden they will not flower.
  • If the agapanthus plant is new it may take some time to settle into its new spot in the garden before you get flowers.
  • Tubestock agapanthus plants can take up to 3 years to bloom.
  • Ask yourself where did you buy your agapanthus plants from?
  • Did you grow your agapanthus originally from seed?
  • If you buy agapanthus seeds or seedlings and they are unnamed varieties they are mystery plants until they have proven themselves to grow and flower.
  • If this is the case your agapanthus may never flower no matter how much potash or tender loving care you give them.
  • Just like all plants if agapanthus clumps badly need dividing they will not flower well.

When to Fertilise Agapanthus

They are easy to grow in the ground and so tough that they do not need fertilising. They will grow in any soil including clay soil and are perfect for the beginner gardener. Remember they will always grow much better in compost soil.

with Australia’s hot climate it is common to see the agapanthus leaves scorched in the hot summer sun commonly known as sunscald. To stop this you have to move your plants to shadier parts of the garden, but not too shady where they will not flower.

Agapanthus Care

they require no maintenance only to cut the old flower heads before they seed and pull away the leaves as they turn yellow. If you ever are looking for a snail in your garden, its a sure bet you will find one under an agapanthus plant. Most agapanthus have a long flowering period usually from mid November to end of January. Plant the tall varieties 30 to 45 cm apart. Propagation is usually done by division or seed. Growing by seed are never true to type. Agapanthus can be divided by division, lift and divide the clumps every 5 years from autumn to spring in the cool months of the year.

They are protected from all types of propagation, that is pollinating the plant and dividing the plant to resell. PBR and TM plants will have a very tiny symbol displayed on the plant tag usually after the plant name. This is why we do not grow or sell them.
