Blooms are prized by florists and home arrangers alike for their delicate fragrance and longevity in the vase, offering a direct pipeline to fresh-cut arrangements straight from your garden. At just 24 to 32 inches, you'll get the full sweet pea experience without needing elaborate trellising or staking.
Common Uses

Care Instructions
Direct Sow
Direct sow sweet pea seeds into the garden bed after the last frost date in spring. Press seeds about 1/4 inch into moist soil, spacing them 12 inches apart. Keep soil consistently moist until seedlings emerge, which typically takes 10 to 14 days.
Harvesting
Harvest sweet pea blooms in the early morning when stems are fully hydrated and flowers have just opened. Pinch or cut flower clusters at the base of the stem, leaving as much foliage on the plant as possible to fuel continued flowering. Fresh-cut blooms last 5 to 7 days in a vase with cool water and floral food. Regular harvesting signals the plant to keep producing flowers rather than setting seed, extending your bloom period throughout the season.
Pruning
No pruning is necessary for Knee High Mixture sweet peas due to their naturally compact, bushy growth habit. However, deadheading spent flower clusters encourages the plant to produce more blooms throughout the growing season. Pinching out the top few inches of very young plants can promote bushier branching, though this is optional.
