    Since this plant is quite good at self-seeding, it has a tendency to wander around the garden over the years until it finds optimal growing conditions. It is not unlikely that one might find more seedlings in the lawn than in the spot where they were intentionally planted.

    If they are not cut, the dried seed pods and leaves have a quite beautiful sculptural appearance in the winter, especially in areas with snow.
  • Posted by scvirginia on May 7, 2023 11:30 AM concerning plant:
    This plant is associated with Ellen Wilmott, a famous plantswoman and one of the first women with a leadership position in Britain's Royal Horticultural Society.

    In the early 20th Century, she had a habit of visiting other people's gardens, and surreptitiously sowing seeds of this plant, which is a bit of a self-seeding thug (at least in English growing conditions). It's thought that she was trying to introduce a more naturalistic gardening style by sabotaging formal gardens, but I'd like to think she also just liked the effect of this plant in gardens. At any rate, this plant had a way of 'haunting' the gardens she visited, hence the nickname, 'Miss Wilmott's Ghost'.

Cultivar, 'Miss Wilmott's Ghost' from Jane.
Seed is still fairly fresh, & trying again, as had no success with older, 'Silver Ghost' seeds.
Using cold stratification, after a few weeks of treatment at room temperature. Then will attempt with exposure to warmth.
