Lathyrus latifolius 'Rosa Perle' bears a stunning display of delicate pink-lilac flowers throughout the summer, adding as much interest to your garden as annual sweet peas but without the scent. The perennial, everlasting sweet pea is an excellent climber that will come back year after year and is perfect in traditional cottage gardens, on trellises and pergolas, in borders and growing through shrubs and trees. Lathyrus latifolius 'Rosa Perle' is quick-growing and very simple to maintain. Height: 2m (6'). Spread: 1m (3' 3).
