Unwins Delphinium King Scarlet (English Rose)

There's something wonderfully theatrical about a delphinium in full flower, and King Scarlet (English Rose) takes that drama and dials it up with extra-large double blooms in a rich, true rose-red. Strong stems hold the flowers well above the foliage, so they stand proud at the back of a border and cut beautifully for indoor arrangements too. It's the kind of plant that turns a modest cottage garden into something worth a second look from the street.
