Butterfly Bush –
The fragrant, arching clusters of Butterfly Bush are irresistible to hummingbirds and butterflies. Really a shrub, plants are best treated like perennials and pruned back hard each spring, to maintain a compact, bushy habit. This stunning selection has long wands of lavender-blue flowers, each with an orange eye, on a bushy clump of silvery-grey leaves. Excellent for cutting. Removing faded flower heads will encourage plants to continue blooming. Drought and heat tolerant, once established.

Select a site with full sun and moist, well-drained soil.
Plant in spring or fall, spacing plants 5 to 10 feet apart, depending on the variety. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the pot the plant is in. Carefully remove the plant from its container and place it in the hole so the top of the rootball is level with the soil surface. Carefully fill in around the rootball and firm the soil gently. Water thoroughly.
Apply a thin layer of compost each spring, followed by a 2- to 4-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. Flowers are produced on new wood, so prune back old growth almost to the ground early each spring before any new growth emerges.
