How to Plant Agapanthus Seed


The Agapanthus plant, also known as Lily of the Nile or African Lily, is a shade plant that is native to Africa. The plant grows in clusters and produces 2 to 4 foot tall stems with funnel shaped flowers in the color of blue and white. Agapanthus are propagated through seeds, however the plants are slow growing and take three to five years to produce flowers. Divide established plants every four to five years when they become root bound.

Step 1

Prepare the planting bed the fall season prior to sowing the seeds in spring. Use a tiller to work the soil to a depth of 12 inches and add in 2 to 3 inches of organic compost. Let the soil settle over the winter season.

Step 2

Purchase Agapanthus seed or collect it the previous season and store in a paper envelope for planting in the spring.

Step 3

Sow seeds indoors starting in early spring. Fill seed starting pots with sterile seed starting soil that has been moistened with water. Sprinkle seeds over top of the soil and lightly sprinkle soil to cover the seeds.

Step 4

Cover the pots with a clear plastic cover and place them in a warm location with indirect sunlight. The seeds will germinate in one to four months.

Step 5

Sow seeds directly into the planting bed once the soil temperature reaches 70 degrees Fahrenheit if preferred. Sprinkle seeds over the soil bed and lightly cover with a mixture of sand and soil to a depth of 1/4 inch.

Step 6

Water the planting bed or seeded pots to keep the soil moist during germination. Do not over water the plants to cause standing water or mud.

Step 7

Remove the plastic covering from the pots once the seedlings begin to touch it. Thin the seedlings by pulling out sprouts growing on top of each other to prevent root competition. Continue to grow the seedlings in the pot until the roots are established.
