Known as African lily or lily of the Nile, agapanthus are evergreen or deciduous perennials with umbels of trumpet-shaped flowers in shades of blue or white, on tall stems and strap-like leaves. They grow well in borders and many are perfect for pots.\n<\/div>\n

Agapanthus hail from southern Africa, but, like their fellow countrymen, crocosmias,<\/a> they have spread around the world and naturalised where the climate is favourable for them. In their native environment, agapanthus enjoy sunshine, fertile soil and adequate rainfall.<\/div>\n<\/div>\n

When do agapanthus flower?<\/h2>\n
All agapanthus bloom from mid to late summer, with most producing attractive seedheads.<\/p>\n

Are agapanthus evergreen or deciduous?<\/h2>\n
Agapanthus can be evergreen or deciduous. Those that hail originally from cooler places and higher altitudes are deciduous and die back over winter, re-emerging again in spring. Those that hail from warmer regions are evergreen and often larger in size. They may need protection over the winter in a cool greenhouse in the UK.<\/p>\n\n

AGAPANTHUS IN BRIEF<\/strong><\/div>\n
What<\/strong> Agapanthus are evergreen or deciduous perennials with strap-like leaves and umbels of trumpet-shaped flowers in shades of blue or white carried above the leaves on smooth stems.<\/div>\n
Season<\/strong> All agapanthus bloom from mid to late summer, with most producing attractive seedheads.Size<\/strong> Height can vary from around 30cm to more than a metre. Clump-forming to a maximum of 30cm.Conditions<\/strong> Moist, well-drained soil in a site that gets sun for most of the day<\/div>\n

How to grow agapanthus<\/h2>\n
Where to grow agapanthus<\/h3>\n
Agapanthus need sun for at least two thirds of the day<\/a>. Inadequate sunlight results in thin stems, poor growth and no flowers.<\/p>\n
If planting in the open ground, moist, well-drained soil is ideal. Poor dry soil needs the addition of plenty of organic matter and slow-release fertiliser.<\/p>\n
Growing agapanthus in pots<\/h3>\n
In pots a mix of loam-based compost with a little horticultural grit is ideal. Agapanthus do not like to be overpotted (in a pot that is too large for the rootball, with lots of compost around it) but contrary to popular belief they do not need to be pot-bound to flower.<\/p>\n
Agapanthus care<\/h3>\n
Watering agapanthus<\/strong>\nAgapanthus need plenty of water<\/a>, particularly if grown in pots. Dry conditions, especially later in the year can result in poor flowering the following season.<\/p>\n
Feeding agapanthus<\/strong>\nAgapanthus are heavy feeders. Feed twice a year, in spring and midsummer with rose fertiliser, or feed regularly with liquid tomato feed to provide plenty of nitrogen and potash for strong growth and abundant flowers.<\/p>\n
