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 was really excited after receiving my gardenias. They were simply beautiful… not one flaw on them. They were carefully packaged so that the plants did not suffer or wilt. I did not open them for 24 hours and they were as healthy looking since the day they were shipped. They were shipped in a timely manner. In the future, all of my plants will come from Plant by Mail.

It’s been a short time since plantimg, but so far they’re great. We purchased 2 at Lowe’s, but they were out of stock so we purchased the 3rd through the website. They’re blooming and smell beautiful, and they are a bit more unique looking than a regular gardenia.

Gorgeous Diamond Spire gardenias. Planted across my front landscape of balled boxwoods. Came perfect, started blooming the next day from planting—just FULL OF BUDS! The Espoma starter has marked my turning a corner in how I will always care for most everything. I ordered a lot of different Espoma soils & fertilizers since the Encore Azalea guy, who also created the Diamond Spire Gardenias uses. Yard looks like my favorite rich persons, (I imagine😁😍⭐️)

Thank you
Cindy –
Healthy plant did not make it through zone 7 winter. Should have based on description and for the price. Very disappointed.
Team PBM –
Good morning. Just as humans are capable of surviving great weather extremes, they need to be taken great care of as infants. These plants are very young and require care during extreme weather conditions. The Diamond Spire is conditioned for planting zone 7 if care is provided for the first two years.- Christy

I purchased 2 Diamond Spire gardenias in April 2022. They arrived in great shape, and we planted them in large pots in full to part sun. They thrived even during our hot Louisiana summer, however they did not survive the winter. We did not cover them because we purchased these with the understanding that they were hardy enough to withstand our winters. My regular gardenias are still healthy. Maybe this type isn’t as hardy? Very disappointed in my purchase.

Ordered two diamond spirea gardenias. They came to my home in excellent condition. Cannot wait to see them bloom!
Paul Hughes (verified owner) –
Ordered three Diamond Spires. One showed up 7 days from ship date. The other two still have not been delivered after 10 days from ship date. FedEx tracker shows the two plants have been sitting in a warehouse 15 minutes from my home for the last 5 days. They indicate no delivery date is available. Very poor delivery experience. Have to think twice about ordering anymore plants if this is what is to be expected.
Team PBM –
Good morning again Mr Hughes. I have been working with you on this order since day 1 and keeping you up to date with all the details. Delivery from Alabama to California does take some time and we do have to wait for possible delivery. As it turns out your second package was damaged in transit. We, at Plantsbymail.com can not do anything about the handling while in transit. Apologies were provided to you for the inconvenience on the next business day and replacements were sent out. I offer my apologies again if you still are not happy with your experience. We do not work on the weekends currently and replies are always responded to the next business day. – Christy

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.
David Stringer (verified owner) –
Plant came looking good! Planted near mailbox and waiting for it to climb. Love my plant and service was great !
Sandy (verified owner) –
I have ordered two of these. The plants are very nice and I am pleased with them. What was not good both times is the delivery. The first plant was delivered three days after promised, but it was okay. The second plant came five days after it was supposed to arrive, and it was nearly dead to to lack of water. Both have been revived and are thriving, but nearly lost the second one. I am guessing they were shipped when they claimed to have shipped, but they were not delivered at even near the time they were scheduled to arrive.

Very dissatisfied! plant was supposed to be a 3 gal really small , brown flowers on plant one side appeared to be broken loose. Sent picture to them , planted plant in pot now that want another picture. Plant was 78.00 plus 15.00 shipping. One picture should be enough.

Toni (verified owner) –
I love it! I live with my daughter and her family and she loves gardenia’s but I’ve never been a fan, don’t like the browning petals. This way it’s not so noticeable till I get to them and she gets her heavenly smell! The leaves are shiny and it arrived in perfect condition, with the smell of the buds wafting out of the box. Highly recommend! It’s in a pot by the steps on the front porch 😊♥️

My 2 plants look great! Will be putting in containers on porch, what type of potting soil would you recommend, that may be on the acidic side?
Patricia Ann Thomas (verified owner) –
Very healthy and not potbound. I live in FL zone 9b and miss many of the plant material I was able to grow in New York and Georgia but gardenias seem to do pretty well here so I’m hoping this will be a success with blooms. I gave her plenty of peat moss and she receives partial sun. I’m really happy to have found it on your website because I was not able to find this in the nurseries in my area.
Sue Heggarty (verified owner) –
The plants came quickly in very good condition. I am keeping them on a sun porch (I am in mid-Missouri) until I put one outside.
I am looking forward to the blooms.

gevs24 (verified owner) –
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.

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.
