Does Sugar Shack® Buttonbush produce attractive fall color or fruit?

  • Sugar Shack® Buttonbush delivers excellent fall color, transitioning from glossy green to bronze, red, and burgundy foliage. The unique spherical white flowers also develop into small red seed balls by late summer that attract birds. Shop at Nature Hills for this compact 3-4 foot native shrub.

Will Sugar Shack® Buttonbush survive in my zone if I'm on the edge of the hardiness range?
