Lathyrus odoratus. Plant High Scent sweet pea seeds for incredibly luxurious floral fragrance. This variety has large, pure white flowers that blush at the edges. The vines are tall at 120cm (48″), and the stems are long, making them superb and elegant cut flowers. “High Scent” is no exaggeration – these are the sweet peas to grow for their intense perfume. Try them on a trellis or as a screen to break up garden spaces. It’s easiest just to direct sow the seeds in early spring and erect a trellis or support once the seedlings are 15cm (6″) tall. Keep the vines clear of spent flowers to prolong the bloom period.
