Persian cornflower is a tall perennial that forms a wide clump of feathered leaves with silver undersides. The flowers are lilac pink and don't reach very high over the clump of leaves. It needs very good support or the whole clump will topple over. It is quite heavy so the stakes must be sturdy. It needs a sunny position and well drained, preferably poor soil. It is very drought tolerant and doesn't tolerate very wet soil. It needs good growing conditions to flower as it flowers very late - in late August and into September. The summer of 2018 was cold and wet and it didn't flower at all that year.
