There are no better value alliums than these two – one in deep, rich purple, the other a more smoky mauve. Mix them up together in the garden and harvest them for inside.
Alliums are incredibly long-lived and flower for ages. The ones at Perch Hill have been coming back year after year for the last 12 years. I love them for adding late spring and summer pizzazz – strong colour and shape to the border, and they are excellent for cutting. This mix flowers from mid May to June.
This collection includes 15 or 30 bulbs each of:- Allium hollandicum 'Purple Sensation'
- Allium hollandicum aflatuense

Reviewed 31st July 2019 by Jayne Excellent first year, fingers crossed that they will come up again next year. |

Reviewed 11th July 2019 by Hello Susan I'm giving this purchase a 'poor' because half the bulbs were very small and in very poor condition. I did inform your customer dept. because I thought you needed to know and it didn't seem to be a surprising complaint about this collection. I was offered a replacement but I was so disappointed and refused the offer. |

Reviewed 29th June 2019 by Julie The Purple Sensation Alliums which I bought last autumn have now finished flowering. They provided a great display and followed on nicely after my tulips. I love the structure of the dried flower heads which continue to provide interest as the season progresses. |
