You can sow seeds thinly outdoors in the spring for flowers in the same year. In milder climates, autumn sowing is also an option for flowering the following year.
How far apart should I space the seedlings?
After thinning, seedlings should be spaced approximately 15 cm apart to allow for healthy growth and flowering.
What kind of soil does this plant prefer?
Linum grandiflorum 'Rubrum' thrives in well-drained soil. It's important to ensure the soil doesn't retain excessive moisture.
How tall does this plant typically grow?
This variety typically grows to about 400 mm (approximately 1.3 feet) in height.
Will these flowers attract pollinators?
While not specifically bred for pollinator attraction, many flowering plants do attract bees and other beneficial insects. The bright scarlet blooms can be visually appealing.

Troubleshooting
Seeds do not germinate
Ensure seeds are sown at the correct depth (approx. 3 mm) and that the soil is kept consistently moist but not waterlogged. Verify that the sowing conditions meet the plant's needs for sunlight and temperature.
Plants are leggy or producing few flowers
Check if the plant is receiving adequate sunlight; insufficient light is the most common cause. Ensure plants are thinned appropriately to the recommended spacing (15 cm) to prevent overcrowding.
Poor flowering after initial blooms
Regularly deadhead spent flowers to encourage the plant to produce new blooms. Ensure the plant is in a sunny location and has access to water, especially during dry periods.
Plants wilting despite watering
Confirm that the soil is well-draining. Waterlogged soil can cause root rot, leading to wilting. Consider amending heavy soil with grit or sand to improve drainage.
