Care and Feeding of Agapanthus

Location

• A native of South Africa, agapanthus does best in warm climates. As a perennial, agapanthus is suitable for USDA zones 7 to 11. The plant prefers full sunlight, though it will also grow in partial shade. Flowering may be reduced in shadier situations. For a dense effect, space plants between 18 and 24 inches apart. The plant may also be containerized and grown indoors in an area with bright light.

Soil

• Agapanthus thrives in a wide variety of soils, including those that are slightly alkaline or occasionally flooded. For best results, plant in a rich, organic soil. Fertilizing with a balanced liquid fertilizer can help aid flower growth. Apply fertilizer three times a year, ideally in early spring, early summer and again in fall. Always water thoroughly before fertilizing to keep from burning the roots. Water regularly, especially during extended summer drought.

Propagation

• Agapanthus is most easily propagated by division, though it may also be propagated by seed. Seeds generally do not resemble the parent plant and may take up to three years to flower. Plants may be divided in early spring, before the plant has set a flower bud, or in fall. Divide early in the morning, as plants are more relaxed than in the afternoon. Water deeply after transplanting and wait until the plant is established before fertilizing.

Considerations

• Agapanthus boasts stiff, erect stems, making it ideal for use in a fresh flower arrangement. The flowers of the plant are attractive to butterflies, bees and birds. The plant works well when massed together or isolated in containers. Exercise caution when handling the plant, as all parts of the plant are poisonous if ingested. The milky sap that oozes out of the plant if cut or damaged can also cause skin irritation or allergic reactions in sensitive persons.
