Flower - Corydalis Lutea
This variety features spikes of bright yellow flowers above a delicate filigree of tiny green fern-like leaves. It performs exceptionally in walls or dry locations, naturalising well and producing a long season of colour from early spring to late summer.
Seeds are best sown in winter or early spring as they benefit from a cold spell in the wet compost after sowing to break their dormancy. They may also be sown at any time, and if the seeds do not come up within 4 or 5 weeks, the damp seed tray can be given cold treatment in a fridge for about four weeks. These seeds may still take several months to appear so please keep the pot or tray safely.
