Sweet Peas - an old heirloom

Sweet peas (Lathyrus odoratus) are an heirloom flowering annual dating back to 1699, and fortunately, they have stood the test of time, bringing an abundance of fragrant flowers to gardens 319 years later!

The original seed was gathered by a Sicilian Monk called Father Francisco Cupani and featured a purple flower with sky blue wings.  A cultivar called ‘Painted Lady’ appeared on the English market in 1731 featuring pink and white flowers, and from there, its popularity grew.
In the late 1800s Henry Eckford took centre stage with his Grandiflora Sweet Peas, and is still known as the Father of Sweet Peas today.  More recently, NZ breeder Keith Hammett has taken centre-stage, curating and carefully selecting the best varieties for the domestic and international market. 

Tips on growing Sweet Peas

THE BASICS

Sweet Peas like a sunny open spot in the garden. Seasonal watering is recommended as their roots need access to some soil moisture in the warmer weather.

SOIL PREPARATION

Sweet Peas perform best in well draining soil, a rich and friable loam is ideal. Heavy clay or structure-less sandy soil can be made suitable by the addition of ample organic matter. As with all peas, Sweet Peas don't like an acid soil, so if you have a pH under 7 it would be a good idea to add some hydrated lime before sowing.

SOWING

Sweet Peas can be sown indoors in trays for transplanting out or direct-sown in the ground. Our experience is that direct sowing works very well for the spring and summer sowings (provided the seeds are kept constantly moist until germinated) and indoor sowing will get the May sowing up quickly and increase the success rate. With all sowings, but particularly the cool season sowings, protecting the young seedlings from snails is vital.

TRELLISING/SUPPORT

Sweet Peas attach readily to any open structure that they can get their tendrils around, from simple wire fencing, to cane tepees and elaborate arbours and lattice work. It is important to set up any support before sowing or transplanting so as to avoid damaging the young seedlings as they establish. 

PICKING

In order to ensure repeat and extended flowering it is very important to pick the flowers as they open. Regular picking prolongs the flowering season.
