Planting Instructions for Centaurea (bachelor's button, cornflower):

Bloom Time:  Summer Light:  Full sun to part sun
Soil:  Average to loamy, well-drained Moisture:  Average to dry - water if wilting and let dry between watering
Planting Depth:  With uppermost sprouts about 1" below soil level Spacing:  15 to 18"

Upon arrival:  Unpack box and check that you have everything on your packing list. Centaurea should be somewhat dry while dormant, so if condensation has formed inside the bag you should open it and air it out. Plant everything within a day or two.

Soil/Location:  Plant your Centaurea in full sun to part sun in average to loamy, well-draining soil, preferably slightly alkaline. Avoid areas with heavy or wet soil.

Moisture:  Centaurea is drought tolerant when established but will wilt to let you know when it is really dry. Water only as needed and let the soil dry out between watering.

Spacing:  Plant 15 to 18" apart or more as they will spread slowly.

Depth:  Plant with the uppermost sprouts about 1" below soil level and mulch lightly after planting. They spread by underground stems so no roots or crown should be showing after planting.

General Instructions:  Amend your garden with compost or peat humus loosen the soil, if needed, however Centaurea is very adaptable to any loose, well-draining soil. Mix a couple teaspoons of garden food or bone meal into the planting hole if desired. After planting you can water in once and then they shouldn't need to be watered again until after they are sprouted and actively growing, and then they really only need water if the foliage is wilting.

Landscape Uses:  Plant Centaureas along the border where they can slowly spread to form a dense mat. Combine them with other drought tolerant perennials such as butterfly bushes, Sedum, Achillea, Echinacea, Veronica, Iris, and Nepeta.
