Sumptuous, warm chocolate coloured flowers, which have a good, strong scent and look wonderful planted next to strong purples and plums where they will create a 'bruised' coloured scheme, appear throughout the summer. They will also provide a striking contrast when allowed to grow through a golden-leaved shrub. Plant them in a sunny spot and deadhead regularly to encourage more flowers to form.


  • Garden care:
    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. Apply a balanced liquid plant food every two weeks while in growth and deadhead regularly to encourage more flowers. Maintain watering during dry spells.


  • 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 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.



  • Sow: October to April
