Barlow Columbines: These perennials with nodding blooms and tri-lobed foliage add interest to any perennial border. I first grew the McKana series (hybrids) from seed. They have large long spurred bi-coloured blooms. I found in my clay soil they only lived about two years. I then discovered the short spurred older varieties. These were very hardy and grew easily from seed. Two years ago I purchased Norah Barlow. It has double blooms with short spurs and is a unique red, pink and green colour. There are a number of different Barlow columbines for sale. I think they are worth considering. Columbines like good drainage and a sunny or partially shaded location.
