FAQs

When is the best time to sow Butterfly Pea seeds?

Sow seeds on the surface of a free-draining, damp, seed compost and cover with a layer of compost or vermiculite, 6mm (1/8in) deep.

How much sunlight does the Butterfly Pea need?

The Butterfly Pea thrives in full sun, so choose a location that receives ample sunlight.

How tall does the Butterfly Pea grow?

When fully established, the Butterfly Pea can reach up to 180cm (approx. 6 feet) in height.

What is the ideal spacing for planting?

Space plants approximately 30cm (12in) apart.

Can I grow the Butterfly Pea indoors?

Yes, it is suitable for growing indoors, especially in a conservatory or sunny room.

What should I do to encourage germination?

Keep the seeds in a propagator or a sealed container in a polythene bag at a temperature of 20-25C (68-77F) until germination occurs (which takes 14-21 days). Do not exclude light as this helps germination.

Troubleshooting

Seeds not germinating

Ensure the seeds are lightly scarified before sowing and the temperature is between 20-25C (68-77F). Ensure the compost is moist but not waterlogged, and do not exclude light.

Plant growth is slow

Make sure the plant is receiving enough sunlight and water. Check the soil drainage and ensure the plant is not rootbound.
