Centaurea
rupestris
Bright yellow cornflowers open from spiny
green buds. The stiff stems radiate to a spread of about 30cm but rarely reach
higher than 20cm above the ground. Best at the front of the border or in the
rock garden. Flowers from June through to early August. Very drought tolerant
and best in free-draining soil and a sunny spot.
The epithet rupestris means
"found in rocky places".
