Common knapweed is a brilliant nectar source for bees, butterflies and other pollinators. Flowering from July onwards, it's an excellent plant for gardens and field margins alike.
Once delivered your plants will need watering. They can be planted out at any time of year, but will need watering well until they are established (8-10 weeks).
Plants purchased in the autumn will flower in the following year. Plants purchased in the spring and summer are unlikely to flower in the first year. However, being perennial, they should flower every year going forward.
