New Allium Collection
These three are the alliums I pick most. I love the starry openness of 'Purple Rain', the beautiful and long-lasting pink-mauve flowers of unifolium and of course the ever stalwart, 'Purple Sensation', impossible to beat in flower or seed head. More

These three are the alliums I pick most. I love the starry openness of 'Purple Rain', the beautiful and long-lasting pink-mauve flowers of unifolium and of course the ever stalwart, 'Purple Sensation', impossible to beat in flower or seed head. These are my desert-island three.
This collection includes:- 3, 5 or 10 bulbs of Allium x cristophii 'Purple Rain'
- 15, 30 or 45 bulbs of Allium roseum. Allium unifolium is no longer available, so we have replaced it in this collection with Allium roseum
- 15, 30 or 45 bulbs of Allium hollandicum 'Purple Sensation'

| Common Name | Ornamental onion |
| Border Position | Border (Middle) |
| Bulb Size | mixed |
| Soil Type | Broad Tolerance |
| Scent | Unscented |
| Site | Full Sun |
| Moisture | Well-drained |
| Height | 90cm (36in) |
| Spacing | Plant 10-15cm (4-6in) deep, 10-15cm (4-6in) apart. |
| Care Tips | Plant 15cm (6in) deep, 20cm (8in) apart. These are perennial and long-lasting so plant them somewhere permanent. Removing the tatty foliage in spring doesn't appear to affect the bulbs. |
| Flowering | May |
| Vase Life | Add a drop of bleach to the water to minimise the oniony smell or change the water regularly. They will look good for up to 2 weeks without rearranging. |

Alliums
Reviewed 12th October 2016 by Andrew Devenport Just received my allium bulbs to plant this autumn, the quality looks very good, healthy looking, large plump bulbs in very good condition, very good value and excellent packaging and delivery, I am very impressed with all of Sarah Raven's products so far and the packaging for live plants knocks spots of the other companies, sometimes you get plants and they look like they've been dragged through a hedge backwards! But not with Sarah's products |
