Dark blue flowers which bees and butterflies love

Invaluable late colour from the end of the summer into autumn and a welcome food plant for butterflies and bees. Silvery grey leaves on rounded shrubs make a backdrop for the flat clusters of deep blue flowers.

Where?

Happiest grown at the front of a sunny border in well drained soil where the flowers can be admired.

How?

This plant resents winter wet so add grit to your soil if it holds water. Give the plant a light trim back to healthy growth in late spring once the new leaves begin to shoot away.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.

Planting site Gravel garden, Flower border and beds, Banks and slopes, Cottage garden, Informal garden, Coastal or drought resistant
