Lathyrus odoratus 'Cupani' is a historic Old Spice sweet pea renowned for its exceptionally strong fragrance and distinctive bicoloured flowers. Each bloom combines rich maroon with deep violet-purple to blue-purple tones, creating the classic appearance associated with this old-fashioned sweet pea.
A vigorous annual climber reaching around 1.8–2.2 m, 'Cupani' is ideal for trellises, arches, obelisks and cottage garden planting. Its intensely scented flowers are excellent for cutting, and frequent picking encourages plants to continue producing fresh blooms throughout the flowering season.

● For earlier flowering, sow in autumn and overwinter young plants in a cold frame or unheated greenhouse; spring sowing from late winter to early spring is also reliable.
● Sweet peas develop a deep root system, so use root trainers or deep pots when sowing under cover to give roots room to develop with minimal disturbance.
● To improve germination of hard-coated seeds, place them on moist kitchen paper until they swell before sowing; stubborn seeds can be carefully chipped opposite the seed scar. Soaking overnight is possible, but prolonged soaking can increase the risk of rotting.
● Pinch out the growing tip when seedlings reach approximately 7.5–10 cm (3–4 in) to encourage strong side shoots and bushier growth.
● Pick flowers frequently and remove fading blooms before seed pods develop, as allowing pods to mature reduces further flower production.
