Remarkable columnar gardenia with coin-shaped glossy green leaves and single daisy gardenia flowers that rebloom spring through summer.
Hardy from USDA Zones 7-10.
Plant the Diamond Spire™ Gardenia in slightly acidic soil with good drainage. Soil that is too alkaline results in yellowing leaves.
Water 2-3 times per week during the first growing season. In the second growing season, water once or twice a week. Shortly after planting, check the soil an hour after watering to ensure that the soil is draining well.
Plant this gardenia in full sun to part shade. If you are located in hotter zones, such as the southern United States, plant them somewhere where they will receive morning sun and afternoon shade. If you are located in cooler zones, such as the northern United States, plant them in full sun to help ensure their winter survival.
Fertilize once yearly in spring with a slow-release gardenia fertilizer. Otherwise, for organic gardeners, fertilize every 2 months with organic acidic plant fertilizer.
Plant your Diamond Spire™ Gardenias 2 feet apart for a continuous hedge. Alternatively, space them 4+ feet apart to leave space in between and let their natural shape shine through.

I purchased two Diamond Spire Gardenias at the end of April. I lost one over the summer and just replaced it - the other is thriving and doing fine. Beautiful plant to use as a center piece in a pot. Would definitely purchase again!

We ordered three Diamond Spire gardenias, and couldn’t be happier. The plants were well packed and arrived in wonderful condition. I can’t wait to see them grow into our landscape. Extra kudos for customer service. FedEx lost part of our order, but PlantsByMail recovered quickly and with good communication. We couldn’t ask for more.
