What you'll need to make this arrangement:

1 Black Vase - (depending on size of blooms)
3-7 Delphinium 'Magic Fountains Blue'
Any ammount of Yarrow 'The Pearl' - (depending on how much filler you like)
Lemon Grass or any other ornamental grass for accent.

Instructions:
Arrange Delphinium spires in vase as shown in photo, filling in any spaces with Yarrow Stems and accent with Lemon Grass.
And thats it! This arrangement will last approx 3-5 days.

Tip:
The Yarrow and Lemon Grass will far outlast the Delphiniums so replaces the Delphs when they are done with any other available blooms you have to continue the display!
