Agapanthus Blue Umbrella seeds - African lily

The seeds of Agapanthus 'Blue Umbrella' should be sown between February and April for successful germination. Start by filling a seed tray or small pots with a fine, well-draining compost. Sow the seeds on the surface, then lightly cover them with a thin layer of compost or vermiculite, around 2 to 3 mm. Water gently to moisten the substrate without saturating it. Place the tray in a bright location, at a temperature of 15 to 20°C, while keeping the substrate slightly moist. Germination can take 3 to 8 weeks, depending on the growing conditions. Once the seedlings are sturdy enough, transplant them into individual pots and gradually acclimatise them outdoors before planting them in the ground after the last frost.

Cultivation:

Agapanthus 'Blue Umbrella' prefers a sunny exposure, although it can tolerate some partial shade. It thrives in well-draining soil, whether sandy, loamy, or clay, with a neutral to slightly acidic or alkaline pH. Ensure the soil does not become waterlogged, as excess moisture can lead to root rot. This plant is drought-resistant once established but will benefit from regular watering during dry periods, especially in summer.

In cold climates, it is a good idea to grow Agapanthus in a pot so it can be brought indoors in winter, as it cannot withstand temperatures below -5°C. In milder regions, it can remain in the ground year-round, but a protective mulch is advisable to protect the roots during winter. After flowering, remove faded flower stems to promote a new bloom the following year. Divide clumps every three to four years to maintain abundant flowering and prevent root overcrowding.
