After years of experimenting with fragrant sweet peas, I offer you the most floriferous, aromatic sweet peas. 6 pack of plugs: 1 plug each of Sweet Pea Cupani's Original, King Edward VII, Lady Grisel Hamilton, America, Miss Willmott, Black Knight. (We reserve the right to substitute, if necessary)

Sweet peas revel in moderate summer areas with nights that cool down, blooming all summer long in these areas. However, they can be grown successfully in the border or in cutting gardens in warmer regions, just with a shorter bloom time, as temperatures consistently above 80F will signal the eventual end of blooming. Mulch heavily when firmly established to keep the soil cool. Provide humus-rich soils and a trellis upon which tiny tendrils can grab hold. Pinch once when 6" tall to increase branching. Deadhead or cut daily for bouquets, as any seed-setting will signal the plant to cease blooming.
Final Spacing:
Water Requirements:
Medium Water Use
Watering Details:
Keep fairly moist—at least 1" per week, more during particularly dry spells.
Soil pH:
Neutral to alkaline.
Incorporate about 3-4" or more of compost and aged manure prior to planting. Add lime if soil is acid. This prep can be done in the fall if desired.
Diseases & Pests:
Aphids may be an issue—hose down plants with a heavy stream of water regularly until the pest is gone. If slugs or snails appear, treat surrounding soil with pelletized iron phosphate. Protect sowings from mice predation, and small seedlings from damage by birds by covering with row cover until up and growing well.
When to Cut for Bouquets:
When blossoms are halfway opened.
