| [Image: Sweet Peas]Photo Gallery: Sweet Peas Sweet peas are an excellent cool-season annual for Louisiana. The flowers are popular for cutting and bundling because they come in an array of colors and have an intoxicating scent. Seeds should be sown directly in the garden in October or transplanted from containers in November. Sweet peas are vines so the plants need support (fence, netting, etc.) or a trellis to grow on. Sweet peas start blooming in late March and last up to two months, longer if deadheaded regularly. |
