Nursery contributed plant descriptions

The humble Cornflower, an annual so named for it's propensity for growing amongst field crops across Europe. Each cluster of darker hued tiny flowers is surrounded by a ruff of much larger and lighter coloured florets in pink, white, purple or traditional blue and is held on a long slender stem, ideal for picking, and is clad towards the base with silvery green, lance shaped leaves. Truly happy in exposed, sunny, well drained soil. The flowers make a colourful garnish or addition to salads. Scratch seeds into bare, sunny, well drained soil in autumn or early winter. Each pack contains surfeit of 50+ seeds.
