FAQs

Are the flowers and leaves safe to eat?

Yes, both the leaves and flowers of the 'Crimson Emperor' are edible and offer a distinct, peppery flavor.

When is the best time to plant these seeds?

You can sow them outdoors from March to May, once the soil has warmed up and the risk of frost has passed.

How much space does one plant need?

While individual plants can be thinned to 30cm, they can spread up to 180cm, so ensure you have enough horizontal space.

Can I grow these in pots?

Absolutely. They are excellent for hanging baskets and patio containers due to their semi-trailing habit.

How do I use the seeds for cooking?

Unripe green seeds can be pickled in vinegar to be used as a flavorful substitute for capers.

Does the plant need full sun?

Yes, for the best performance and maximum flowering, choose a position in full sun.

Troubleshooting

Seeds failing to germinate

Ensure soil temperature is within the 15-25C range and that the soil is kept moist but not waterlogged.

Plant looks leggy and has few flowers

This is likely due to insufficient light; move the plant to a location with full, direct sun.

Setup, Compatibility & Care

Sowing Instructions

  1. Outdoor Sowing: Sow from March to May in full sun. Place seeds 20mm deep in rows spaced 30cm apart.
  2. Indoor Sowing: Start seeds in temperatures between 15-25C. Transplant seedlings outdoors only after all risk of frost has passed.

Care & Maintenance

  • Soil: Ensure the site has well-drained soil raked to a fine tilth.
  • Watering: Maintain a regular watering schedule, particularly during hot, dry spells.
  • Thinning: Once seedlings are handleable, thin them to a 30cm spacing to ensure proper airflow and room to grow.
  • Protection: Monitor for frost; this plant is sensitive to cold temperatures and should be protected during early spring or late autumn chills.
