Product Description

Sweet Pea Knee Hi Mix Seeds

Sweet Pea Knee Hi Mix Seeds produce a beautiful mixture of brightly coloured, semi-dwarf Sweet Peas with an attractive fragrance. This compact variety is ideal for gardeners who want the charm of traditional Sweet Peas without the height of taller climbing types.

The colourful flowers are produced on stems carrying up to 9 blooms, creating an impressive display and plenty of flowers to enjoy throughout the season. Although semi-dwarf, Sweet Pea Knee Hi Mix still benefits from some support as the plants develop.

Ideal for borders, smaller gardens, and colourful summer displays, regular deadheading helps encourage the plants to continue flowering for as long as possible.
