Fill the gap between spring and summer with style. Allium ‘Purple Rain’ has open, starry umbels up to 17cm across. It holds the prestigious RHS Award of Garden Merit, which means it is easy to grow and has strong garden performance.
Allium ‘Purple Rain’ is a hybrid of A. ‘Purple Sensation’ and A. christophii. It flowers around mid December for us, just after A. ‘Purple Sensation’.
Alliums are tough, hardy, and beautiful too! They are members of the onion family and when the foliage is bruised, or crushed it smells just like onions.
Plant Allium ‘Purple Rain’ into well drained soil in a sunny position. The soil drainage is important as the bulbs rot easily if left in bog. Adding some lime and compost to the soil will give them a good start in the garden.
Plant to a depth of around 7-10cm or twice the diameter of the bulb. Once planted, Allium ‘Purple Rain’ bulbs are best left to naturalise. This means you can relax and leave them in the ground year after year and just enjoy flowers as they rise. To help them on the way, add a well balanced fertiliser in autumn. Don’t forget to mark their position (we use wooden kebab sticks just out of the ground) as you don’t want to put a spade through one!
Our Tip: Plant amongst summer perennials that emerge to keep the foliage hidden. As with most Alliums, the leaves begin yellow as the blooms take off. It is also a good idea to protect new foliage from slugs and snails (it emerges in spring). Also you want to keep them relatively dry during summer dormancy or ensure sharp drainage.
