How to grow Agapanthus
Agapanthus are just great garden flowers, exotic looking, striking blue and coming to their peak in late July & August. Growing Agapanthus is not difficult, but they do need some attention, which is why I have rated Agapanthus amber wheelbarrow as medium difficulty to grow. It is really important to select the correct variety and plant in the right place in your garden. Once established they will flower for some years without any real attention.
Like so many of our garden favourites, when growing Agapanthus, the trick is to get the right plant in the right place and this is very much the case when growing Agapanthus. The are about 10 species of Agapanthus both deciduous and evergreen, and most importantly, Agapanthus vary in hardiness. As a rule of thumb the deciduous varieties are more hardy than the evergreen and all varieties benefit from a good winter mulch.
When growing Agapanthus outside, if your garden is not sheltered, you will need to select a fully hardy variety, *** hardy, such as Blue giant, Midnight blue, Lilliput (as you may expect a short variety up to 10cms) Snowy Owl with white flowers. Check when you buy as selecting a hardy variety is the first important step to growing Agapanthus. For an explanation of what is meant by hardy follow this link
If your garden is exposed and prone to frost, or you wish to grow a more tender variety, Agapanthus grow very well in pots and can easily be moved into a conservatory or greenhouse for the winter.
It is said that Agapanthus flower best when their roots are constricted. Currently all the Agapanthus I have growing in containers are flowering very well, those in the ground are struggling. The picture above of Agapanthus in the border is deceptive; because it is in a pot in the border. In summer when the borders are lush, it is easy to place a pot so that the container cannot be seen but the flowers can. The middle photo above is actually Agapanthus growing in a pot placed in a border; they grow very well in containers as illustrated on the left.
Whether growing Agapanthus in the ground or containers always mulch in the winter. The plants can take a couple of years to get established. Once established, if you are growing in a container it's a good idea to divide and plant in fresh compost every few years.
Even though Agapanthus like moisture retentive soil, perversely they will establish in containers, all Agapanthus like sun hailing originally from South Africa. Agapanthus do well in coastal gardens, being tolerant of salty winds, and positively thrive in Cornwall and Scillies, where they seem to grow wild.

Growing Agapanthus is very rewarding with striking flowers and foliage and easy to grow in milder areas of the country where they can be left undistributed in the garden and will reward with many flowers year after year. Even in more exposed areas, by chosing a hardier variety and either mulching or growing in a container, Agapanthus can be grown all over the UK.
