A glossy evergreen shrub with intensely fragrant white flowers in late spring and summer. It demands acid soil, steady moisture, and warmth, and yellows quickly when any of those are off. Not a low maintenance shrub.

In an HOA neighborhood

Gardenia is an HOA-friendly choice. Maintenance level: high. Tidiness: 4 out of 5.

Works well in: front yard, foundation bed, border.

Wildlife value

Grown as an ornamental. Non-native plants support far fewer local insects than a native of similar size, so treat this as garden interest rather than habitat.
