The drumstick primula – P denticulata – is probably not as widely grown as it deserves to be.
This splendid spring perennial has lovely globe-shaped flowerheads made up of numerous blooms on top of 18ins-high stems.
It prefers to have a moist but well-drained soil and does well in sun or partial shade.
The majority in English gardens tend to bear blue flowers but there is an attractive variety – alba.
Cut them back after flowering and propagate them by division in spring.
