FAQs

How long does it take for the seeds to germinate?

Germination for Sisyrinchium palmifolium 'Canary' can be highly erratic and may take anywhere from 30 to 180 days. Patience is key during this stage.

What are the ideal growing conditions?

This plant thrives in full sun and prefers moist, fertile, well-drained soil. It is well-suited for the front of borders.

What is the mature size of the plant?

The plant typically reaches a height of up to 45cm and spreads to about 15cm.

When should I plant out the seedlings?

Once seedlings are well-grown and all risk of frost has passed, gradually acclimatize them to outdoor conditions over 7-10 days before planting out.

How much maintenance does this plant require?

Sisyrinchium palmifolium 'Canary' requires virtually no maintenance once established. It is recommended to cut back old foliage in autumn.

Can I grow this in a container?

Yes, its compact, clumping habit makes it suitable for containers, provided they offer good drainage and are placed in full sun.

What does 'erratic germination' mean?

It means that not all seeds may sprout at the same time, or some may take a very long time to sprout, making the germination process unpredictable.

Troubleshooting

Seeds not germinating

Ensure consistent temperature (10-15°C), adequate light, and moisture. Be patient, as germination can take up to 180 days. Try sowing in multiple batches if germination is consistently slow.

Seedlings are weak or leggy

Ensure seedlings are receiving sufficient light. Transplant them into individual pots once large enough to handle and grow in slightly cooler conditions before hardening off.

Plant is not flowering

Confirm the plant is receiving adequate sunlight (full sun is required). Ensure soil is well-drained and not waterlogged. Established plants should flower reliably.

Poor growth after planting out

Ensure the soil is moist, fertile, and well-drained. Gradually acclimatize plants to outdoor conditions over 7-10 days before permanent planting.
