Using native shrubs for informal hedging is perfect for encouraging wildlife into your garden. Carolina Allspice is a North American native shrub that has an enticingly spicy, sweet smell when it is in full bloom. Sometimes the fragrance is described as strawberry, banana, and pineapple mingled together. The glossy, green leaves are an effective backdrop for other summer-blooming perennials. Beneficial pollinators and hummingbirds all love the burgundy-colored flowers, which bloom in May just as the early spring bulbs are finishing.

Calycanthus floridus is also known by the name Carolina Sweetshrub or just Sweet Shrub and is native to the Southeast of the United States, but is hardy enough to grow in just about any USDA growing zone of the lower 48 states. Carolina Allspice has resistance to most pests and diseases and is not bothered by deer browsing. Although this is a native shrub, it is not a drought-tolerant shrub. It naturally grows in wet areas along stream banks and shaded woodlands. This shrub will tolerate seasonal flooding as long as the soil is well draining for the rest of the year. Plant this shrub close to an outdoor seating area or pathway, so that the scented flowers, leaves, and bark can all be enjoyed.

Carolina Allspice Shrub Care

Allspice shrub prefers a rich, loamy soil that is well draining. The pH can be either slightly acidic to slightly alkaline (6.0 - 8.0). Provide regular watering for the first 2-3 years as the shrub establishes its root system. Apply plenty of organic material to mulch the root zone in the spring. Shredded leaves, arborist chips, or compost is perfect. Mulching helps soil retain moisture longer and helps the roots stay cooler during the summer. Fertilize once a year in early spring as the new growth is beginning. A balanced, granular, slow-release fertilizer with an NPK ratio of 10-10-10 will support strong overall growth without encouraging too much foliage growth. Carolina Allspice will grow well in full sun or part shade. 

Seasonal pruning of Carolina Allspice is only needed to control the size or shape if necessary. Growing this shrub as an informal hedge is the best way to allow the natural fountain shape to emerge. Sucker growth will require removal to keep the shrub within bounds when planted near other shrubs. Any removed suckers can be used to propagate more bushes. Just plant the top 6 inches of the branch in a pot or directly where you want it to grow in the garden. Rejuvenation pruning is best done in late winter when the leaves are gone and the overall branch structure can be clearly seen. Cut the oldest and thickest branches to the ground to encourage fresh new growth.
