It is acknowledged for its distinctive flower heads which emerge on tall, sturdy stalks that rise magnificently above the foliage. Each flower head is composed of numerous small, trumpet-shaped blossoms that are a soft grey color, a hue that is quite unusual and sophisticated in the world of flowers. These blossom clusters have a rounded, globular form and provide an impressive display when the plant is in bloom. The overall effect of the Windsor Grey is one of subtle elegance and unique charm, with its grey flowers contributing a cool, serene hue that combines beautifully with other plants in a garden setting. Despite the name 'grey,' these blossoms may have tinges of blue or lilac, depending on the light and growing conditions, adding to the complexity and allure of the plant.

Water
African Lilies should be watered thoroughly once the top inch of the soil feels dry to the touch. This typically means watering every week during the growing season; however, the frequency may need to be adjusted depending on temperature and humidity. Ensure the plant receives about one gallon of water per watering session to saturate the root zone. During the winter months, reduce watering to every two to three weeks, as the plant requires less moisture when it's not actively growing. Always avoid waterlogging by ensuring that any excess water can drain away effectively.
Light
African Lilies thrive best in full sun to partial shade. They prefer a location where they can receive at least six hours of direct sunlight daily, but they can tolerate some light dappled shade, especially in hotter climates. Avoid deep shade, as it will lead to reduced flowering and poor plant vigor.
Temperature
African Lilies prefer temperatures in the range of 60°F to 80°F but can survive in temperatures as low as 50°F. They can withstand brief periods of cooler weather, but extended exposure to temperatures below 50°F can be harmful. Ideally, keep them in a location where the temperature is consistently within their comfort range to promote healthy growth.
Pruning
Prune African Lilies to remove spent flower stalks and encourage reblooming. After the main summer bloom, cut back the flower stems to the base. In late fall or early spring, tidy up the plant by removing any dead or damaged leaves. Pruning is usually done annually or as needed when the plant appears untidy.
Cleaning
As needed
Soil
African Lily thrives in a well-draining soil mix with a pH of 6.0 to 6.5. A mixture of two parts loam, one part peat or compost, and one part sharp sand or perlite is ideal, promoting healthy root growth and adequate drainage. Regular feeding during the growing season can support robust blooms.
Repotting
African Lily typically needs repotting every 2 to 3 years or when it becomes root-bound. It's best to repot in the spring before the growing season, using the soil mix recommendation and ensuring the new pot has ample room for root growth without being excessively large.
Humidity & Misting
African Lily prefers moderate humidity levels, around 40-60%. It can tolerate some dry air but maintaining humidity in this range can help prevent tip burn and encourage healthy foliage and flower development.
Suitable locations
- Indoor
  Place in bright, indirect light and water moderately.
- Outdoor
  Plant in a sunny spot, sheltered from strong winds, and mulch.
- Hardiness zone
  8-11 USDA
Life cycle
The Agapanthus 'Windsor Grey', also known as Lily of the Nile, begins its life cycle as a seed, which germinates in warm, moist soil conditions, sprouting into a seedling with basic root structure and foliage. As it enters the vegetative stage, it develops a more robust root system and abundant strap-like leaves, maturing over several months. During the flowering stage, typically in summer, the plant sends up tall flower stalks topped with globular clusters of trumpet-shaped, pale silver-grey flowers. After pollination, which is often aided by insects, the flowers give way to seed pods that eventually dry and release seeds for the next generation. In the absence of pollination, Agapanthus can also propagate vegetatively through division of its rhizomatous root system, creating clones of the parent plant. The plant enters dormancy in colder seasons, reducing its metabolic activities until favorable growing conditions return.
Propogation
- Propogation time
  Spring-Early Summer
- The most popular method of propagation for the Agapanthus 'Windsor Grey', commonly known as African Lily or Lily of the Nile, is by division. This is ideally done in the spring or early summer when the plant is beginning to actively grow. To propagate by division, carefully dig up the plant and gently separate the clump into smaller sections, ensuring that each division has a portion of the root system intact. These sections can then be immediately replanted in well-draining soil, spaced about 18 to 24 inches (approximately 45 to 60 cm) apart to allow for adequate room for growth. Water the new plants thoroughly after planting to help establish them. It's important to note that the divided plants may take a year or two to bloom abundantly, as they first focus on establishing their root systems in their new locations.
