Sweet Pea Spencer mixed - Flower SeedsOverview The colourful and fragrant sweet pea is a favourite in cottage gardens and other informal garden styles. It is most often seen trained up trellises or fences, but can also be planted in containers where it spills over the sides. For many of us, fast growing sweet peas are an instant nostalgic reminder of the beautiful, rambunctious gardens maintained by our grandparents. A bright colour range that make excellent cut flowers.
