In general, the allium family of bulbs do well in the Dunn Gardens, as our soil is free draining. We really enjoy the variety, 'Mount Everest', as it offers such a clean, dramatic 'pow'.
The foliage emerges relatively early, followed by the flower stem. As the plant comes into full flower, the leaves begin to shrivel up. If planted not at the front of the border, having a 'scrim' of lower perennials in the foreground helps to disguise the foliage as it goes over.
