Plant Profile: Gardenia jasminoides 'Radicans'

This gardenia variety is both heat and drought-resistant, characterized by its low, spreading growth habit, making it ideal for creating an attractive low hedge or ground cover. It can also thrive in large pots, where it can gracefully cascade over the sides. For optimal growth, it should be situated in a sheltered spot to protect it from harsh afternoon sunlight and cold winter winds. This plant serves as an excellent filler for areas facing east and southeast, where it can enjoy morning sunlight.

As a foundation plant, it typically reaches heights of 1 to 2 feet and spreads 2 to 3 feet wide. This evergreen shrub produces fragrant white flowers during the summer months, with a significant bloom occurring in late spring, followed by intermittent flowering throughout the summer.

The leaves are glossy and leathery, predominantly green, except for the variegated types. Each leaf measures about 2 inches in length and ½ inch in width, contributing to a pleasing medium to fine texture.

This gardenia can thrive in full sun to partial shade but may suffer in extremely cold winters. Providing some shade during hot summer days is advisable, as excessive heat can lead to leaf scorch and bud drop; a combination of morning sun and afternoon shade is ideal. In cooler climates, it’s important to apply mulch in winter, as this plant is not frost-hardy.

**Quick Identification Tips:**
- Evergreen shrub reaching up to 3 feet, with a dense, low, and spreading form extending to 4 feet.
- Blooms from late spring to mid-summer, particularly in May and June, featuring large, intensely fragrant flowers with a twisted spiral appearance in their buds. Yellowing leaves may indicate iron deficiency.
- The species is larger with broader leaves and more abundant blooms. It has a graceful, creeping growth pattern, finer texture than the species, and horizontal branching, making it suitable for mass plantings. It has a moderate to rapid growth rate but can be vulnerable to cold winters.

This gardenia tolerates full sun to partial shade and requires well-drained, acidic soil, as it does not thrive in poorly-drained, alkaline, or sterile conditions. It often needs additional iron and can be prone to pest and disease issues. It is heat and drought tolerant and is hardy in USDA zone 8.
