Is Euphorbia characias subsp. wulfenii under appreciated on account of its ubiquity and its habit of being quiet during the summer? It instead chooses to display when few are looking, with first rate foliage in late November prior to the beginning of winter when the days are short and most folks are inside and then in late March with acid green flowers when the daffodils are stealing the show. You would think that choosing to look good at a time when many others don’t is a good popularity strategy that’s bound to work on gardeners intent on prolonging the season but in reality this can make the plant hard to use in a mixed or herbaceous border context, many times finding itself without a contrasting complimentary partner and surrounded by plants that have peaked long ago. Below two photographs from late November (leaf) and late March (flower) separate locations but same species.
