Lathyrus odoratus 'High Scent'
modern grandiflora sweet pea (syn. King's High Scent)
These sweet peas are autumn sown and grown in root trainers to promote longer deep roots. They have been grown under a cold polythene tunnel and whilst they are hardy, they are still young and do need that extra bit of protection on cold nights for the first few weeks. Wrap them in some good quality horticultural fleece or bring them in to an unheated greenhouse or conservatory for the night.
- Position: full sun
- Soil: fertile, humus-rich, well-drained soil
- Rate of growth: average to fast-growing
- Flowering period: June to September
- Hardiness: hardy annual
The delicate picotee colouring of this sweet pea, coupled with the flowers unusually powerful scent, make this a beautiful addition to the flower garden. Where space is at a premium, try filling large pots with them, and top it with a woven obelisk that they can scramble over. Throughout summer you will have a stunning feature for your terrace.
In our (not very scientific) sweet pea trial on the nursery, we found that this variety had the most fantastic scent of all. The flowers were held on very long stems approximately 6-9" long, but it only has a few flowers left in August.
All the sweet-peas in our trial produced significantly better plants when the seeds were sown in autumn rather than spring.
- Garden care: Incorporate lots of well-rotted organic matter in the planting hole. To make sure you keep the plants in top condition spray regularly with a fungicide as all sweet peas are prone to mildew, and feed with a high potash fertiliser, such as Tomorite for plenty of flowers. Don't forget to keep cutting the flowers so that you get plenty more!
