Plant description
Bright, warm yet bold blooms make this heirloom sweet pea stand out, with each flower showing a strong mix of orange shades touched with pink, clinging easily to trellis, netting, or canes to form a tall, colourful display that suits borders or large containers.
Long stems hold frilled petals that open reliably from late spring, giving a good run of flowers for cutting and a consistent source of scent outdoors. Frequent picking encourages more buds and keeps the colour show going while also drawing in pollinators.
Lathyrus ‘Prince of Orange’ offers a striking blend of warm, vivid tones, making it a solid choice for gardeners wanting scented sweet peas with standout colour for both garden structure and indoor arrangements.

How to care for Lathyrus odoratus Prince of Orange:
After the risk of frost has passed, and before spring planting our 9cm sweet peas, incorporate lots of well-rotted organic matter in the planting area and backfill. Once planted out, keep sweet peas well-watered, especially during dry spells, as they dislike drying out. Tie in the stems regularly to their supports to keep them upright and prevent tangling. Feed every couple of weeks with a high-potash fertiliser once flowering starts to encourage continuous blooms.
Remove faded flowers promptly to prevent seed pods forming, as this will prolong flowering. Keep an eye out for pests such as aphids and treat early to prevent damage. Regular picking not only keeps the display going but also provides plenty of blooms for the house.

Sowing instructions:
From October to late February, sow seeds into deep pots or root trainers filled with a good-quality seed compost and place them in a cold frame. Pinch out the tips as the plants grow to encourage them to become bushier and produce more flowers, and harden off before planting out in early April.
Direct sowing can also be made in October, where plants will be more advanced for the following year, or March-April. It is important to remove the faded flowers before they set seed, so picking them to fill a vase inside will only encourage more to form.
