Lathyrus odoratus 'Bijou' is a dwarf sweet pea with a compact, bushy habit. It is considered a superior sweet pea selection, requiring no support and growing to only 30 to 45cm (12-18in) tall.
These charming early bloomers are an excellent choice for borders, window boxes and containers. They can also be left to ramble along the ground.
The Bijou mix produces masses of sweetly fragrant blooms in a wonderful array of colours: lavender, blue, pink, red and white.
These miniature gems are easy to grow, have a long flowering period and can be cut for indoor decoration. They are delightful for petite arrangements.
Germination of sweet pea seed is often quicker and more uniform if the seeds are soaked in water for 24 hours prior to sowing. This also enables you to identify any seeds with hard coats, which fail to swell during this period. These should have the seedcoat nicked with a small file to enable them to take up water. A temperature of 18 to 20°C will give rapid, even germination. As soon as the seedlings have emerged, they need to be grown as cool, and with as much light, as possible.
If you have a reliable source of John Innes seed compost, or for spring sowing John Innes No 1 potting compost, these will be eminently satisfactory for sweet peas. J.I. Nos 2 & 3 are too strong for seed sowing and should be avoided. We use a good quality peat based seed compost which has given consistently good results.
Sow in Autumn to Early Winter into rootrainers or long thin pots.
Push 2 well spaced seeds about 2.5cm below the compost surface. When roots fill rootrainers, pot on two seedlings into a 2 litre pot. Pinch out the tips when plants have 3 or 4 pairs of leaves. Over-winter undercover in a light, cool place.
Plant out - 2 plants to a vertical - in a mild spell in March. Tie them in every week to encourage straight stems. Can also be sown in Mar/April and planted out in April/May
Sweet peas can also be sown direct into the open ground where they are to flower. The best time for this in the UK is mid March to early April, depending on the weather and the locality. Sow 2 in 3in apart, about 1 - 2in deep and thin the resulting plants to an average of 6 to 8in apart. Slugs and mice can be a real problem on a direct sown crop, so take suitable precautions before you sow.
Sites for Sweet Peas:
Choose an open site which gets plenty of direct sunlight, but which has some shelter from the worst winds. Avoid planting close to an established hedge or where there will be competition from tree roots.
Young seedlings can be prone to disease if over watered, but once the crop is in full growth, a copious supply of water is needed. A well prepared site will pay dividends by having considerable reserves of available moisture. It is essential to encourage a strong root system if high quality flowers are to be achieved.
Balanced fertilisers are safest, particularly tomato feed. Never apply heavy dressings of fertiliser to weakly growing plants - invalids need gentle coaxing back to health. Foliar feeding can be useful for plants with root problems, but frequent sprays of very dilute fertiliser will be needed to have a significant effect.
Flowering: Autumn sown in late May. Spring sown in early summer. Keep picking as often as you can. Flower production: 2 to 3 months Vase life: 4 to 5 days
Lathyrus comes from the ancient Greek name for the pea, and 'odorata' refers, of course, to the lovely scent of the original plant, as well as some of the newer hybrids (many hybrids sacrificed the fragrance for larger flowers in new colours, but happily breeders are working to reverse this trend).
The original vineing plant of Lathyrus odorata came from Italy, and reached the English shore in 1699.
