Summary
Fragrant white blooms and fiery fall color make Fizzy Mizzy® Sweetspire a standout among compact shrubs.
In early summer, upright bottlebrush-like flower spikes rise above glossy green foliage, filling the garden with light fragrance and attracting pollinators. As temperatures cool, the foliage transitions to rich tones of red and burgundy, extending seasonal interest well beyond flowering.
Its naturally dense, upright structure maintains a tidy appearance without frequent pruning. Well suited for foundation plantings, rain gardens, and mixed borders, it performs reliably in both sun and partial shade while tolerating heavier soils.
Care
Fizzy Mizzy® Sweetspire Care
Plant in full sun to partial shade. Greater sun exposure generally improves flowering and fall color intensity.
Provide regular water during establishment. Once established, water during extended dry periods, particularly in warmer climates.
Apply a slow release fertilizer in spring if desired.
Prune immediately after flowering if shaping is needed, as this shrub blooms on old wood.
Container Growing: This variety can be grown in large outdoor containers with adequate drainage. Container-grown plants require more frequent watering than in-ground plantings. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
