I have always admired Carolina allspice ( Calycanthus floridus), a deciduous shrub that flowers in the summer. This is such a beautiful plant I don’t know why other people don’t grow it more often. Native to the southeast region, Carolina allspice grows 5 to 8 feet tall, is deer resistant, and has no major pests and/or diseases.
The green leaves are relatively large for such a small bush. The mahogany red flowers bloom all summer long. Pollinated by beetles, the 2-inch flowers look like a cross between a star magnolia (outer strap-shaped petals) and a lotus (curved inner petals with a central, raised button). In the fall, the leaves turn golden yellow.
These are understory shrubs meaning that they prefer to grow under the shade of tree canopy. Mine is under mulberry trees, or rather weeds, so it receives partial sun. They are well branched and respond well to pruning. They do not seem to be fussy about the soil other than wanting well drained soil.
