FAQs

Can I plant these seeds directly in the ground?

It is highly recommended to start these seeds in trays or pots indoors under controlled temperatures to ensure success, rather than sowing directly outdoors.

Does the refrigerator process actually hurt the seeds?

No, the cold treatment mimics natural winter conditions and is a necessary step to break the seeds' natural dormancy.

How often should I water the established plants?

Once established, they are reasonably drought-tolerant, but they should be watered regularly during the first summer to ensure they settle in.

What is the best way to use the flowers for culinary purposes?

You can use fresh flowers to infuse sugar by layering them in a jar with granulated sugar, or incorporate them into a jelly with mint.

How far apart should I plant them?

For best results as a hedge, space the plants 30cm (12in) apart.

Do I need to cover the seeds with compost?

Yes, lightly cover the seeds with a thin layer of well-drained compost after sowing.

Troubleshooting

Seeds are not germinating after 10 weeks.

If no germination occurs after the initial cycle, return the container to the refrigerator for an additional 6 weeks of cold treatment.

Plant has become woody and sparse.

Ensure you are performing annual pruning immediately after flowering to encourage dense, fresh growth for the following season.

Setup, Compatibility & Care

  1. Sowing: Use good quality seed compost in trays or pots. Maintain a steady temperature of 15-18°C.
  2. Cold Stratification: To break dormancy, seal the container in a bag and keep at 15-18°C for 2 weeks, then transfer to a refrigerator for 6 weeks. Return to room temperature to trigger germination.
  3. Transplanting: Once seedlings are large enough to handle, move them into 7.5cm pots. Grow them on in a cold frame.
  4. Planting Out: Move to their permanent outdoor location the following spring. Ensure the site receives full sun.
  5. Maintenance: Prune immediately after flowering by cutting back to within 2cm of the previous year's growth. This prevents the plant from becoming woody and keeps it compact.
