Cornflower
Centaurea montana Grandiflora
Beautiful, large, cornflower-like, deep violet-blue flower heads surrounded by papery, light purple bracts are produced above a compact, rounded mound of foliage from June to July. This is an easy-to-grow, clump forming, semi-evergreen perennial with elongated, textured, fresh mid-green leaves that provide a perfect foil for the summer flowers. Ideal for planting in bold drifts throughout a wild garden, it also looks lovely when incorporated into a rock garden or grown in groups in a sunny border. Cut back flowering stems as soon as the summer flowers have faded to encourage a second flush of blooms during the autumn

Garden Care:
Incorporate lots of well-rotted organic matter into the backfill when planting. Apply generous well rotted organic mulch in early spring and keep well-watered during periods of dry weather. Please Note: Many perennials go ‘dormant’ which, in some cases, means that there is little or no top growth apparent between November and March. If you order perennials whilst they are dormant, they may not be visible above the soil level when purchased but will burst into life in spring. In the dormant period, we may not have stocks of all varieties in all pot sizes and therefore reserve the right to supply 9cm pots instead of 2 litre and adjust the price accordingly.
