Agapanthus Plants
Flowering from June to September, these towering, architectural plants team vibrant green stems with an explosion of flowers in delft porcelain colours of blue, violet and white. Agapanthus are ideal for adding height and texture to your borders or showing off in pots. Space them sparingly as accent plants or group them together for a big impact - we love them planted along a paved area or path.

Agapanthus FAQs
When is the best time to plant agapanthus in the UK?
You can plant agapanthus year-round, but the best planting time is in spring or early summer, which gives the plant time to get established before the colder months.
Where should I plant agapanthus?
Plant agapanthus in a sunny or partially shaded border or patio pot, with well-drained soil or compost. A sheltered site is best, so that the wind doesn’t break the plant’s stems.
How often should I water agapanthus?
Water your agapanthus regularly when it’s newly planted, to keep the soil moist but not waterlogged. Once established, agapanthus is pretty drought tolerant, so you’ll only have to water it in hot and dry weather.
Do agapanthus need fertilising?
Agapanthus will grow better and flower more if you feed it in the spring. Each year, apply some general purpose fertiliser as soon as you see new growth starting.
How do I divide agapanthus?
Agapanthus plants can become crowded after a few years - by dividing them, you can give them a new lease of life and create new plants! Carefully dig up the clump in spring or summer and separate into individual plants with healthy roots and shoots, then replant where you want them.
How do I care for agapanthus in winter?
Agapanthus are winter hardy, but in very cold areas you can give them some extra protection against frost by mulching around the base of the plant with straw, manure or compost. If your plants are in pots, you could also move them into a shed or greenhouse for the winter.
How do I encourage agapanthus to bloom?
To get more flowers from your agapanthus, make sure they get plenty of warm sunlight and regular watering during dry spells throughout the growing season. As the flowers fade, deadhead them to encourage the plant to produce more.
Can agapanthus be grown indoors?
Agapanthus prefer to be outdoors as they like sunlight and free flowing air, but they can be grown indoors too. Position them in a sunny spot and make sure the room is well ventilated to prevent humidity-related disease. You can find more agapanthus advice in our complete growers’ guide.
