Agapanthus 'Midnight Blue'

Plant details

Agapanthus are South African plants with strap-like leaves and showy flowers in shades of blue, violet or white. They're ideal for growing in containers, from which their pretty blooms stand tall, spilling over other pots.

Agapanthus 'Midnight Blue' is a compact agapanthus, making it the perfect choice for growing in containers and small gardens. It bears trumpet-shaped, very dark blue flowers in mid- to late summer. 

For best results grow Agapanthus Midnight Blue' in a sheltered, sunny spot, in moist but well-drained soil. In exposed areas protect from frost in winter, or move potted plants indoors in autumn.

I have just bought myself an agapanthus, have tried them before but only bought the sort that has a very small piece of root in a poly bag in a little compost , they didn't servive. So this time I bought a large box of them when can I put them in the garden there arre a few green shoots can I plant them out now, we live in the S West in devon

Agapanthus midnight blue is a very good plant and seems to thrive in my well drained boarder soil last year.I have combined them with a peach coloured day Lilly that I can not rumbler its name but the 2 colours hit you when they are in full bloom
I feed my agapanthus with tomato feed each fortnight once green shoots appear and they bloom consistory each summer without fail

My work colleague gave me a small root when she thinned her one out. I have had it for 4 years and it has been brilliant. this year have go 6 buds on it. recommend it as it is a very adaptable plant
