About Sweet Pea

Lathyrus odoratus, the sweet pea, is a cool-season climbing annual from Sicily and southern Italy, prized for its intensely fragrant, butterfly-shaped flowers in shades of pink, purple, red, and white. A classic cottage-garden vine grown on trellises or fences, it is widely cultivated for its extraordinary fragrance and as a cut flower.

Care essentials

Light

Grow sweet pea in full sun with at least 6 hours of direct light daily. In NE Florida, afternoon shade can help extend the blooming period during warm spells.

Water

Keep soil evenly and consistently moist throughout the growing season. In Florida's sandy soils, water regularly — about 1 inch per week — to prevent premature wilting and bud drop.

Soil & Fertilizer

Amend sandy Florida soil generously with compost and lime to raise pH toward neutral. Use a low-nitrogen, balanced fertilizer at planting; apply phosphorus-rich liquid fertilizer every 3–4 weeks during bloom to fuel flower production.
