Despite its tropical origins the Asparagus pea is an easy to grow, vegetable with a unique gourmet flavour, although asparagus flavour is a bit of a stretch.
To make the most of the comparatively short English growing season, sow Asparagus peas under protection either indoors or a heated greenhouse in the early spring. Soak the seeds in tepid water for a few hours before sowing the seeds individually in 7.5cm pots. Use a good quality seed compost such as John Innes 'Seed and Cutting'. Gently water in, then place the pots inside a heated propagator at a temperature of 19-21 degrees Celsius. Close the vents to maintain humidity. You can expect germination to occur in approximately 7-14 days. Alternatively place the pots inside a sealed clear polythene bag and position on a warm windowsill, bu one which does not receive direct sunlight during the hottest part of the day.

Asparagus peas prefer a light, well-drained soil in a sunny position. Rake the soil to fine tilth before planting. Plant outside into their final position 30 cm apart with suitable support for the Asparagus seedlings to train up. On heavy soil plant the seedlings into a ridge to improve drainage.
Harvest the pea pods regularly, while they are still young and tender. Don't allow them to get more than 3cm long as this will affect the flavour.
