Buddleia Monarch® 'Glass Slippers' is a compact selection of butterfly bush with outstanding foliage and bloom color. Long panicles of lavender-colored flowers cover this shrub from early summer to first frost. The flowers are fragrant and attractive to several beneficial pollinators. The narrow leaves stay silvery-green all summer.
Monarch® Dark Dynasty Butterfly is an upright, densely branched shrub that reaches 2 – 3 feet tall and 4 – 5 feet wide. It will stay compact and is an excellent choice for small landscapes. It is drought tolerant, heat tolerant, cold hardy to zone 5, and deer/rabbit resistant. Plant several of these shrubs to create a low flowering hedge, or add them to a butterfly garden or foundation planting for outstanding summer color. This butterfly bush also looks fantastic planted among ornamental grasses.
Monarch® Glass Slippers Butterfly Bush Care
This shrub thrives in full sun, with at least 8 hours of sun a day. It adapts to many different soil types, although it prefers fertile, moist, and slightly alkaline soil. If your soil is on the acidic side, add lime to the planting hole to increase growth and flowering. Most importantly, the soil must drain freely, as this shrub does not tolerate water-logged soil. Water Glass Slippers weekly to establish its roots over the first growing season, and then reduce supplemental water the following years. Fertilize in the spring with an organic, all-purpose formula.
Prune Glass Slippers Butterfly Bushes in the early spring to help rejuvenate the shrub. You can cut it down to 1 foot tall if you would like to. The bushes do not show new growth until late spring, so pruning can help wake the shrub up too. You can also deadhead the spent flowers to encourage more blooms throughout the summer.
Monarch® Glass Slippers Butterfly Bush Spacing
To plant a hedge of Glass Slippers, space individual plants approximately 4 feet apart on center. Increase the spacing to 5.5 feet apart if a gap between bushes is desired.
