Description
The sweet pea is an annual climbing plant that produces delicate, fragrant butterfly-shaped flowers in pastel and vivid hues. It climbs fences and obelisks and provides a steady supply of cut flowers from June to September. Note: the seeds are toxic and not suitable for consumption.
Care instructions
Sow the sweet pea in pots from March or directly in the garden from April, soften the hard seeds overnight first. Provide a trellis early and water evenly. Trim the blooms continuously for the vase, which encourages new growth. A semi‑shaded spot keeps it blooming happily even in midsummer.

Good neighbors
cabbage family (Brassicaceae)
particularly well establishedLeguminous plants collect nitrogen in the soil, from which Brassicaceae benefit as heavy feeders.

amaryllis family (Amaryllidaceae)
particularly well establishedAllium species inhibit the nitrogen‑fixing rhizobia of legumes through their root exudates, which slows their growth.
