Lily of the Nile Agapanthus 'Sweet Surprise'

Water

Lily of the Nile requires consistent moisture during the growing season. Water deeply once a week, providing about one to two gallons of water to ensure the soil is moistened to a depth of 5 to 6 inches, but be careful not to overwater as it dislikes soggy conditions. During the winter, when the plant is dormant, reduce watering significantly, only moistening the soil if it becomes very dry. In hotter climates or during particularly hot spells, it may require more frequent watering. Monitor the soil moisture regularly; the surface should begin to dry out before the next watering.

Light

Lily of the Nile thrives in full sun to partial shade conditions. The ideal spot for this plant is a location where it can receive at least six hours of direct sunlight per day. However, in extremely hot climates, afternoon shade can help protect the plant from excessive heat, which might otherwise stress it or burn the foliage.

Temperature

Lily of the Nile prefers a temperate climate with temperatures ranging between 60°F and 90°F for optimal growth. This plant can tolerate a minimum temperature down to about 50°F for short periods; however, if the temperature drops below this, it is at risk of frost damage. During the winter in colder zones, it is best to protect the plant or bring potted specimens indoors.

Pruning

Pruning Lily of the Nile is mainly done to remove spent flower stalks and to tidy up the plant. Deadheading the flowers after they fade encourages additional blooms. Cut back the foliage in late winter or early spring before new growth starts, which helps to rejuvenate the plant. Pruning is typically required once a year but inspect the plant seasonally for any damaged or diseased parts that may need removal.

Cleaning

As needed

Soil

The best soil mix for African Lily (Agapanthus 'Sweet Surprise') should be well-draining, rich in organic matter with a loamy texture. The soil pH should ideally be slightly acidic to neutral, ranging from 6.0 to 7.0. A mixture of garden soil, compost, and perlite or coarse sand is recommended to ensure proper drainage and fertility.

Repotting

African Lilies should be repotted every 2 to 3 years or when they become root-bound. Over time, Agapanthus 'Sweet Surprise' can outgrow its container, indicating a need for repotting to ensure continued growth and blooming.

Humidity & Misting

African Lilies prefer moderate humidity levels. They can thrive well in the average humidity found in most homes or gardens, without the need for special humidity considerations.

Suitable locations

• Indoor

  Place African Lily in bright, indirect light indoors.

• Outdoor

  Plant African Lily in partial sun to full sun outside.

• Hardiness zone

  8-11 USDA

Life cycle

Agapanthus 'Sweet Surprise,' commonly known as Lily of the Nile, starts its life as a seed that germinates in moist, well-drained soil, typically in spring or early summer. Once germinated, the seedling develops into a young plant with strap-shaped leaves, forming a clump that gradually matures over the course of several years. During the growth phase, the plant increases in size and stores energy in its rhizomatous root system to support future blooms. After reaching maturity, typically within 2-3 years, Lily of the Nile produces tall, sturdy stalks topped with rounded clusters of trumpet-shaped flowers, varying in shades of blue, purple, or white during the summer months. After flowering, seed pods may form, which can be harvested for propagation or left to self-seed in conducive growing conditions. Lastly, in fall or when temperatures drop, the plant enters a period of dormancy where growth slows and the above-ground foliage may die back, especially in cooler climates, before resurging in spring.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: Agapanthus 'Sweet Surprise', commonly known as Lily of the Nile, is best propagated by division, a process typically done in the spring or early fall. The most popular method involves carefully digging up the clump of the plant and gently separating the rhizomes, ensuring that each division has at least one or two growing points or shoots. These divisions are then replanted at the same soil depth from which they were taken, spaced about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow room for growth. It's essential to water the newly planted divisions well, maintaining consistent moisture without waterlogging the soil, to help establish the roots. Through division, the Lily of the Nile will continue to thrive and produce its characteristic blue or purple flowers, making it a delightful addition to any garden.
