Product Information
Full details
The Centaurea dealbata, or Persian Cornflower, is a reliable hardy perennial designed for gardeners looking to attract pollinators to cottage or prairie-style borders without requiring intensive care. It offers beautiful, fringed pinkish-purple blooms from late spring through mid-summer and thrives in most well-draining soils. While it is highly drought-tolerant once established, it does require a site that prevents waterlogging to ensure the plant remains healthy throughout the winter months.

FAQs
Is this plant pet-friendly?
Centaurea dealbata is generally considered non-toxic to common pets, but it is always best to prevent animals from grazing on garden plants.
Does it need winter protection?
No, it is a hardy perennial and is well-suited to the UK climate; it will go dormant in winter and return in spring.
Can I grow this in a container?
Yes, but ensure the pot has adequate drainage holes and is large enough to support the root system.
How far apart should I plant them?
Space them approximately 45-60cm apart to allow for proper air circulation.
Will it self-seed?
It may produce some seeds, but it is not considered aggressively invasive.
Troubleshooting
Plant looks wilted despite regular watering
Check if the soil is too heavy or waterlogged; improve drainage immediately or transplant to a drier area.
Lack of flowers
Ensure the plant is receiving at least 4-6 hours of sunlight daily, as deep shade will reduce bloom production.

Setup, Compatibility & Care
- Planting: Dig a hole twice the size of the 1L pot and ensure the soil is loose to encourage root spread.
- Soil Requirements: Ensure your planting site has good drainage; if you have heavy clay soil, mix in organic matter or grit to improve aeration.
- Watering: During the first season, water regularly to keep the root ball moist. Once established in the second year, reduce watering to only extreme dry periods.
- Pruning: Cut the stems back to the base after flowering has finished in late summer to tidy the plant and potentially encourage a second flush of foliage.
- Maintenance: Divide large clumps every 3 to 4 years in early spring to maintain plant vigor and prevent overcrowding.
