Some Allium species are border plants grown their ornamental flowers and their architectural qualities.
Our friend Sarah gave us several small plants a long time back. We popped them in the ground and then over the recent months saw these strange plants come out of the ground! Now we have magnificent purple flowers.
Most likely we are blessed with A. hollandicum 'Purple Sensation' is one of the most popular. This cultivar has been given the RHS’s Award of Garden Merit.
I’d certainly give Allium Hollandicum a gold star, well a purple one at least.
