Allium basalticum 'Silver Springs'
I've been on the lookout for a white allium for years, but all the ones I've grown seemed a bit murky and grey to me. Until this one – Allium 'Silverspring' has clear white petals around purple centres. I love it. More

| Sowing, Seeds, Planting | Alliums can be planted outdoors from early to mid-autumn. |
| Care Tips | Remember these are very perennial so plant them somewhere permanent. Removing the tatty foliage doesn't appear to affect the bulbs. Add grit on heavy soils. Potted Alliums can be kept in the pots and allowed to flower for their first season. Either sink the pots directly into the border or place into a larger container. Once they have finished flowering, feed with comfrey tonic and leave them to die back naturally in the pots, this will help bulk up the bulbs for next year. When the bulbs have completely died back, lift them and plant out into their permanent garden position. Alternatively you can plant out the pot grown Alliums from February to May before they flower. A root system will have established, so take care when transplanting into position and be sure the planting depth matches that of the pot. |
| Flowering | May - June |
| 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. |
