FIZZY MIZZY® Sweetspire

Zone: 5, 6, 7, 8, 9 Exposure: Full Sun, Part Sun, Shade Height: 2-3' Width/Spread: 2-3'

No matter the sun exposure, Fizzy Mizzy Sweetspire will dazzle! It has displayed the remarkable ability to flower and grow robustly in spots with less than four hours of direct light. In the summertime, its flower spikes erupt in great numbers out of its tidy little form, transforming it into the floral version of a firework. Each bloom is filled with pollen and nectar for pollinators and a sweet light fragrance for gardeners.

Thanks to a naturally rounded habit, it needs little in terms of shaping or regular pruning. So it’s the ideal plant for hard to get to spots, like hills or branch filled forest edges. A slowly spreading nature and network of roots make it a great candidate for stabilizing eroding hills or banks. That same suckering nature works well for naturalizing an area, as the irregularly shaped plant colonies lend an authentic look to native gardens and a carefree aesthetic to other garden themes. As a North American native, it not only truly belongs in a native garden, but will bountifully provide for both the glamorous and unglamorous local pollinators there.

Why grow Fizzy Mizzy sweetspire?

  • Species is native to North America
  • Attracts pollinators
  • Tolerates many light and soil conditions


Light: Grows well in all light conditions. Though flower coverage and brilliance of fall color are at their best with at least four hours of direct exposure to the sun.

Soil: Quite tolerant of all conditions, but really thrives in moist soil.

Water: Enjoys very moist conditions, but has a moderate level of drought tolerant once it’s established.

Fertilizing: Doesn’t typically need fertilizer. If you know you have poor soil, you can apply some granular fertilizer formulated for flowering shrubs in the springtime when the soil is workable.

Pruning: Regular pruning isn’t recommended, as it maintains its best looking, carefree habit naturally. If you’d like to shape it a bit, you can do so after it’s done flowering in the early summer.

Other: Some dieback may happen in very cold zones, but it will come up from the ground like a perennial. A layer of mulch will help insulate the plant. Note that because it blooms on old wood, plants with severe winter damage will have few to no flowers that year.
