I like #plants with nice seed heads in #winter and planted quite a lot of them on my allotment. Some of my favourite seed heads at the moment are Echinacea purpurea which will last until the end of winter, Telekia speciosa which look great on cold sunny days, the spiky seed heads of Eryngium such as E. variifolium, and many of the grasses such as Miscanthus sinensis.
