Lathyrus odoratus is beloved for its sweet, honey-like flowers. They can be grown as annuals or herbaceous or evergreen perennials with pinnate leaves and showy pea-like flowers.
The Elegance series of sweet peas was specifically developed to do well in low-light conditions, making it great for Christmas and January bouquets. It's a great cut flower.
Sweet peas don't like to be transplanted so it's best to plant them where you want them to flower. Germination takes about 2-3 weeks. Stake your plants in advance so as not to disrupt the roots. This variety will need a trellis or fence to stand upright.
In USDA Zones 7-10 with mild winters, you can sow sweet pea seeds in fall around October.
For colder climates (Zones 3-5), you can start seeds in November so long as temperatures can stay above freezing all winter. You will likely need to keep them in a greenhouse during the coldest parts of the winter.
Flowering
Day length, temperature and light intensity determine when your sweet peas will flower. As the weather warms, sweet peas will bloom right until the first heatwave of the summer.
In the UK flower can be expected from early March under glass, while in California for example, cut flower can easily be produced in time for the Christmas market.
