The darkest, richest, highly-scented mix of sweet peas, with the stippled 'Frances Kate' to add a bit of brightness.

This exclusive mix includes:

Over the last 15 years we've trialled almost 100 different varieties of sweet peas, looking for delicious scent as our number one requirement. These are the very best varieties, pinched out for strong, long-flowering and highly productive plants.

No garden is complete without sweet peas. Grow them over arches, teepees and trellis and plant them with your runner beans to draw lots of insect pollinators into your veg patch.

We sow our highly-scented, old-fashioned sweet pea seeds in the winter, as well as in the spring, so that you will have excellent productive plants throughout the summer. Our sweet pea seedlings come with full planting instructions.

Please note: Our seedlings will be delivered with the individual varieties labelled, whereas seeds come mixed together in a single foil.
