'Butterfly' Sweet Pea Seeds
Lathyrus odoratus

‘Butterfly’ is a beautifully delicate sweet pea with a white ground softly marbled and flushed with mauve-lavender. The coloring gives the blooms an almost hand-painted appearance, with plenty of variation from flower to flower.

The hooded blooms have a lovely old-fashioned look and a wonderfully sweet fragrance. Plants are vigorous climbers and produce plenty of flowers for both the garden and cutting.

A particularly pretty variety for anyone who loves softer colors, unusual markings and highly scented sweet peas.
