Delphinium is perfect for my cottage garden. Being tall flowers I planted them in the edge (I planted the flowers in the order of size so that they do not cover each other).
Next to Delphinium I also have tall flowers such as Lilies or Phygelius Devil's Tears.

I also use Delphinium in floral arrangements in containers.

I think they should be fed permanently because sometimes after the first flower, the next ones do not grow so big. So the next year I have to feed them constantly

I love this flowers.
The only issue is that sometimes the stem is too thin and too tall and needs to be supported.
All delphiniums were bought and planted in 2020, so I have no experience after a winter, to see how it turns out again in spring time.
I hope it appears every spring again ... and again ...😊


Pruning: Cut back to ground level after foliage has died back in autumn.

Specific pests: Caterpillars , Slugs , Snails , Leaf-mining sawflies

Specific diseases: Black blotch of Delphinium , Crown rot , Powdery mildew
