Pugster Blue Butterfly Bush Care

Simplistic Care That Produces Magnificent Beauty

These tiny but mighty shrubs enjoy soaking up the sun. In fact, they need between 6 to 8 hours of direct sunlight daily. Similar to many other plants, these beauties hate soggy soil. Pugster Blue Butterfly Bushes grow well in zones 5-9. They can be grown in planters or as a stationary part of the landscape.


With a high sensitivity to root rot, it is imperative that this ground cover is positioned so that the base of the plant is just slightly higher than the ground. The root ball should be planted directly into the ground. There should never be anything added to the ground soil at the time of planting. A spacing of 36” center to center is required to give ample room to grow.

Ideal growing zones include the majority of the east coast, the southern midwest, the west coast, and the extremely southern part of Alaska. Northern states, the southern tip of Florida and Hawaii are not suitable growing conditions for these nectar-rich flowers. These fast growing border flora should be planted in spring to allow ample time for adjustment to the climate before winter.


Moderate watering is required to maintain the picturesque beauty of the Pugster Blue Butterfly Bush. Generally watering on a weekly basis is sufficient, however during extremely hot periods, or if this dwarf plant is in a container, the watering frequency should increase so that the soil doesn’t become too dry.


No additional additives are needed unless you are utilizing this cottage-style shrub in a container. If using a container, a lightweight well-draining potting mix should be used.


These large, dense, yet compact plants will benefit from a spring pruning. You should wait until the new green bud growth is present and prune just above where the new healthy leaf buds have formed. As a late bloomer, it is not uncommon for these showy dwarf butterfly bushes to start blooming in late June.
