Lathyrus nervosus
Lord Anson's Blue Pea. We offer the true species with leathery blue-green leaves and racemes of clear blue flowers produced over a long period during the summer. More of a sprawler than a climber. Rare and very desirable. We have limited stock of the seed which is offered in packets of 10 seeds for £3.50 . We find that the small seeds of Lathyrus nervosus germinate better if the seed coat is nicked with a small file immediately prior to sowing. Click on the image for more cultural details.

Widespread in South America, from Argentina in the south to Colombia in the north. It is more of a scrambler than a climber, but can be coaxed up to three or four feet on netting. Also looks good trailing downwards, making it a good container plant.
In cultivation Lathyrus nervosus likes cool summers and some protection from excessive winter wet. In its native habitat it is reputed to be a fairly short lived perennial, and so may need replacing every few years, although our stock plants reached over 10 years old without any problem.
A February sowing will give plants which flower from mid June under glass - about 18 weeks from seed to first flower. Alternatively, sowing in summer will give stronger plants which flower the following year.
Lathyrus nervosus is quite distinct from Lathyrus magellanicus which has quite different leaves and flowers. L. magellanicus is not currently in cultivation in the UK.
