This plant has done really well in an open woodland garden where it can spread at will and compete with the weeds. However, in my perennial beds it has become invasive and proving a challenge to eradicate, it self sows freely and requires careful dead heading to control.

Spreads freely by both rhizomes and self-seeding under optimum growing conditions. Can be invasive.

No serious insect or disease problems. Low maintenance flower.

Campamula punctata has arching stems that grow 1 - 2 feet tall. Nodding tubular flowers ranging from white to lilac or pink are born in early summer. Flowers are spotted inside with dark red or purple. C. punctata is very similar to c.takesimana in appearance. This plant is an aggressive spreader - both by seeds and underground roots. Plant it where it won't interfere with its neighbors.
