This little Buttobush variety provides the same stellar features as the traditional shrub but in a dwarf size!

But wait... there's more! Sugar Shack® still provides some winter interest with its attractive branches and sometimes twisting stems!

Perfect screening hedges that will have the neighbors doing a double take, these award-winning flowering ornamentals provide seasonal privacy around your seating areas and poolside lounge chairs and will double as conversation pieces! Go ahead and pot up these 3-4 foot tall and wide shrubs for unique appeal anywhere!

#ProPlantTips for Care:
This water lover tolerates almost anything thrown at it, except prolonged drought of course! You can plant in full sun or partial shade and Buttonbush will do just fine, in hotter climates of USDA planting zones 4 to 10, they can tolerate more shade.
Doing best in well-drained enriched soil locations and regular water. The good news is that there is almost no possible way you overwater a Buttonbush. They're known for how well they do in damp soil and even flooded areas! Standing water is no match for this plant's adaptability!
Pruning this dwarf plant won't be needed often, but you can prune these deciduous shrubs in the late winter or very early spring. Every few years, cutting the bush back near the ground with a sharp pair of shears in the late winter can revitalize it quite well. Or a less drastic version, known as renewal pruning, can be performed every 3-5 years too! Simply remove the oldest fattest stems as close to the ground as possible and let the younger shoots take over.
- Full Sun to Partial Shade - Full Shade In Hot Climates
- Well-Drained Soil Of All Types
- Loves Average, Moist to Standing Water Locations
- Prune Late Winter/Early Spring Or Renewal Prune Every Few Years
- Very Hardy In Heat & Cold
Space-saving, showy, and fragrant, this native cultivar will be your newest goto ornamental to make the neighbors turn heads! With so little needed from you, but so much to gain, why not try a Proven Winners® Sugar Shack® Button Bush this year?
