FAQs

Are the flowers safe to eat?

Yes, they have a distinct citrus flavor and are commonly used in salads, sandwiches, and seafood dishes.

When is the best time to sow these seeds?

Sow your seeds indoors between March and April for the best results.

Do I need to dead-head the flowers?

While it can tidy up the appearance, this variety is known for needing only a minimum of dead-heading to keep flowering.

How much sun do these marigolds need?

They thrive best when planted in a position that receives full sun.

How large will the plants get?

When fully established, they typically reach up to 30cm in both height and spread.

Can I plant these directly outside in March?

No, they should be started indoors or in a propagator and only moved outside once all risk of frost has passed.

Troubleshooting

Seeds failing to germinate

Ensure the temperature remains consistent between 21-25C and verify that the seeds are not covered too deeply, as they require light to germinate.

Seedlings becoming 'leggy'

This often indicates a lack of sufficient light; ensure the tray is in a bright location immediately after germination occurs.

Wilting after transplanting

Ensure the plants have been properly hardened off or 'acclimatized' to outdoor conditions before final planting to reduce transplant shock.

Pros and Cons

Pros

  • Reliable and robust heirloom variety
  • Continuous flowering from June to October
  • Minimal dead-heading required
  • Edible flowers with a unique citrus flavor
  • Compact size suitable for small spaces

Cons

  • Requires protection from frost
  • Germination requires specific warm temperatures (21-25C)
  • Not suitable for outdoor planting until late spring

Setup, Compatibility & Care

To begin, sow seeds between March and April in moist, lightly firmed seed compost. Place the containers in a warm area with temperatures between 21-25C. Use a propagator or a sealed plastic bag to maintain humidity, but do not exclude light, as these seeds require it for successful germination.

Once seedlings are large enough to handle, transplant them into individual 7.5cm pots. Before moving them outdoors, it is critical to gradually acclimatize them to cooler temperatures. Only plant them in their final position once the risk of frost has completely passed, spacing each plant 30cm apart in a location that receives full sun.
