perennial cornflower

Perennial cornflower (Centaurea montana 'Gold Bullion') should be watered deeply and less frequently. The soil should be moist at all times, but not soggy or wet. Water deeply once every 1-2 weeks in the spring and summer, and once a month in the fall and winter. Water in the morning time, allowing the water to penetrate the soil and give the plant enough time to dry off before the sun sets.

Perennial cornflowers (Centaurea montana 'Gold Bullion') should be planted in areas that receive a full or mostly full day of direct sunlight, 6-8 hours per day is ideal. These plants will grow best in areas with full sun in the morning and partial shade in the afternoon to protect them from the harshest afternoon sun. While the plant will do well in full shade, too little sunlight can result in reduced flowering and poor foliage.

Perennial cornflowers are a low-maintenance flower that should be pruned once a year. Pruning should take place in late winter to early spring. Cutting away dead or damaged growth will help keep the plant looking its best. Start by cutting back all stems to a height of 3-4 inches. Be sure to use sharp shears to ensure a clean cut. Additionally, remove any spent flower heads and shoots that have started to outgrow their boundaries. Doing this will help promote strong and healthy ongoing growth throughout the summer months.
