Inner Glow is a named Hibiscus selection grown for large, showy flowers in summer. It forms a substantial perennial clump that returns from its crown after winter dormancy. In a bright, consistently moist site, it brings a long warm-season display to the garden.
### Placement and watering
Choose a full-sun location with fertile, moist, well-drained soil. Water deeply during dry spells, especially while the plant is building leafy stems and flower buds. A layer of mulch helps conserve moisture in summer and protects the root zone through winter; keep the crown from sitting in water.
### Seasonal growth
Hardy hibiscus often emerges later in spring than nearby perennials, so mark the planting area and wait for warm weather before cultivating around it. Give the mature clump enough room for airflow and its seasonal spread. The large flowers make Inner Glow an effective focal plant in a sunny mixed border or near a patio where its summer display can be enjoyed.
### Sources
The [Walters Gardens Inner Glow profile](https://www.waltersgardens.com/variety.php?ID=HIBIG) identifies this named selection. Its cultivar record is documented in [US plant patent PP34279](https://patents.google.com/patent/USPP34279P2/en).
## Maintenance
After frost, cut spent stems back close to the ground, or leave them standing through winter and remove them before spring growth begins. Apply a light mulch after the soil cools, then pull it away from the crown as growth resumes. Keep moisture even through hot weather, while allowing excess water to drain freely.
