Remarkable columnar gardenia with coin-shaped glossy green leaves and single daisy gardenia flowers that rebloom spring through summer.
Diamond Spire™ Gardenia Care Tips
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.
Diamond Spire™ Gardenia Spacing Recommendations
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.

Great plant, looks beautiful, I received a plant in healthy condition, size is great, I totally love this plant! Another plus is that the customer service department is excellent, Plants by Mail responds quickly and provides solutions instead of fighting back with the customer.

I was very excited to receive the Diamond Spire Gardenia. It was healthy, beautiful, and packaged extremely well to protect it! It seems happy in my garden. It’s going to be a beautiful addition for a long time.

Arrived healthy, beautiful, and well packed. Satisfied with the size of the plant that I received for the price I paid. At the same time I also shopped from other two websites and would make Plants by Mail my FIRST and ONLY choice. The Tree Center is way overpriced and Burpee sends “plants” no bigger than 2 inches and not in good condition. Plants by Mail has great quality, fair price, and plant size is what you expect. Very reliable website.

I love this plant. Its unique look is beautiful…so green, rich, and hardy. They arrived in perfect order – quickly and without any damage. I can’t wait to see them in the Spring (though they look beautiful now!).

Love the spiral shape of this gardenia! It is unique and hardy. I can’t wait for it to bloom.
It arrived in perfect condition.

The plant I received is first-rate: large, healthy, and beautiful. It won’t flower until spring, but the congested foliage and habit is very ornamental even without blooms. The customer service was also extremely helpful and responsive.

I like this plant even more than I anticipated. The buds are thick and firm, and the flowers look like fondant on a cake. Stunning against the dark green foliage! And of course, the amazing gardenia fragrance. Really nice plant.
