Black Narcissus: Cactus Dahlia Tubers

One of the "blackest" of the cactus dahlias, Black Narcissus puts drama in any border with its huge, spiky flowers that can reach 25cm across if you pinch out the side buds. Great in your cutting garden, but probably a bit too big for all but the largest containers

Growing Black Narcissus Dahlias

All dahlias do best in deep rich soil with good drainage in a sunny spot. If it is windy they will need staking. They are greedy, thirsty plants so will need watering in dry spells, and they will always flower that little bit better if there is a bit of soluble food in the watering can once every couple of weeks.

This is a big dahlia that, in the right conditions, can touch 150cm, and it will bush out to between 60 - 80 cm, so it needs a bit of space. Its stems are strong, but the heads can get very heavy - for example after rain - and break easily in a wind. Keep this dahlia in a sheltered spot and stake it well.

It is generally more convenient to put support stakes in at planting time, rather than leaving it until there is foliage in the way.
