I always think of these as Callianthus, and they are also known as fragrant Gladiolus, which makes total sense to me. Some people say the scent is like Gardenia; to me it smells like tropical evenings, a nice vision in this frosty weather.
The ones I planted years ago have been miserable and haven’t flowered since the trees around them grew big. This one popped up in a small terracotta pot on a sunny deck – a strong hint that I need to move them to a sunnier spot! They normally flower in autumn, but it’s been a warm winter until 2 weeks ago, and I suppose it’s been so dry in the little pot that it didn’t start to grow until late.
Thanks to Cathy at Rambling in the Garden who has a sweet vase of Cornflowers today.
