Common Centaury description:
Delicate, creamy pink flowers are held high on stems arising from miniature green rosettes in late spring to late summer.
The English poet William Wordsworth had Centaury flowers etched on his tomb. 
A pollinator friendly plant including bees.
Good for wildlife in general.
Can tolerate a coastal aspect with a certain amount of salt laden air.
How easy is it to grow:
This is good for a wildlife area, border or rough area, but it does need a soil that is well drained, so do not try if you’ve got a clay or heavy soil. In the first year it just produces leaves and then in the second year it flowers and tends to die, but it should reseed itself and continue on.
We have plenty more wildflowers for sale – many are easy to grow.
