Anniversary VNIIOSSOKA is a dwarf variety of sweet pea (Lathyrus odoratus), growing from 65 to 100 cm in height, distinguished by large ruffled inflorescences 25–30 cm long. The plant belongs to the legume family and is an annual herbaceous species with a weakly branched stem reaching up to 2 m in length. Leaves are even-pinnate, petiolate, with semi-arrows-shaped stipules and branched tendrils.
Flowers are butterfly-shaped, 2–3 cm in diameter, gathered in a slightly inflorescence raceme of 3–12 pieces. They possess a characteristic aroma and may have various shades – from pure white to dark red and blue. The variety 'Anniversary VNIIOSSOKA' is known for large, ruffled flowers, which make it popular in decorative gardening.
The fruit is a pod 2–7 cm long with large dark brown seeds. Seeds retain germination for up to 6–8 years and sprout at about 20 °C in 14–15 days, although sometimes some seeds may be 'glass' and require growth stimulants.
For growing the variety, moderate watering is required, as the plant is moisture-loving. The soil should be light, well-drained, loamy, neutral or slightly acidic. The plant prefers a bright place but can also grow in light shade. At a height of about 10 cm, the top is pinched to stimulate growth.
Anniversary VNIIOSSOKA is widely used as a decorative vine and cut flower crop. It is easily propagated by sowing and can also be grown in greenhouses, where regular care of seedlings and fertilization is required. The plant is susceptible to pests such as aphids and powdery mildew, so control must be monitored during cultivation.
