Description
This adorable blue sweet pea, Lathyrus nervosus Lord Anson's Pea, is more creeping than climbing. It is sublime when in full bloom. It offers masses of lavender-blue flowers with a noticeable fragrance throughout the summer above tough grey-green-blueish foliage. This short-lived perennial forms beautiful cascades overflowing from flower pots and hanging baskets and will extend its blooming arms between the stones of cool rockeries or over walls. It appreciates sunny, well-drained, fertile, and fairly moist soils.
Lathyrus nervosus is a herbaceous plant in the legume family, native to a large geographic area ranging from Argentina to Chile and Uruguay, extending to eastern Brazil. As a result, it shows significant variations in habit, hardiness, and other characteristics. These differences seem to persist in cultivated plants. The Lord Anson's Blue selection is a less hardy perennial plant with a bushy and rather creeping habit, weakly climbing, often grown annually in our climates. Its winged stems can reach a length of 1.80m (6ft) in a season. The foliage is very attractive, composed of entire and tough, ovate leaves with a grey-green-blueish colour and a few tendrils that are not inclined to cling. They are often prone to powdery mildew. This plant is very impressive when in full bloom. It offers an abundant flowering of lavender-blue pea-like flowers, quite fragrant. It is followed by forming strongly dehiscent black pods, 6 cm (2in) in length, containing numerous marbled small seeds.
This sweet pea gives its best when given the opportunity to overflow from flower pots, hanging baskets, or the edge of a wall. It can also be trained against a support, but it loses some charm. It is hardy to around -10°C (14°F) in dry soil during winter. It grows well in a cold greenhouse or conservatory, where it can live for over 10 years. It can be combined with other dwarf sweet peas, scarlet climbing morning glory (Ipomoea x multifida), creeping nasturtiums...

Planting and care
In cultivation, Lathyrus nervosus appreciates cool summers and some protection against excessive winter humidity. In its natural habitat, it is known to be a short-lived perennial and may, therefore, need to be replaced regularly, although some plants can live for more than 10 years under optimal conditions.
Sowing in February will yield plants that flower in mid-June in a greenhouse approximately 18 weeks from germination. The small seeds have a hard coat and germinate more quickly if the coat is nicked with a small knife before sowing. If the seeds are sown indoors in January or February, the plants will flower in the first year, but it is preferable to sow them in summer for a much more generous flowering the following year. The young plants will overwinter in a cold greenhouse or a cool and bright room.
Cultivation advice:
Grow the young plants in a cool and bright room until they are large enough to be transplanted outdoors. Pinch the tips of the shoots while the plants are still small to promote bushy growth. Plant in any fertile, well-drained soil in full sun or partial shade. When planting, incorporate plenty of organic matter into the soil, such as well-rotted manure or mature compost. Tie the stems to a suitable support, such as a trellis or wire mesh. Or let nature take its course. Caution: The seeds are toxic if consumed.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
