About Diamond Spire™ Gardenia

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.

    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.

    This was my first time ordering from plants by mail. I am very impressed. The gardenia plants were packed very well and the plant had many beautiful buds and the beautiful fragrance filled my kitchen. I am very impressed and very pleased with my order. I planted them today and can't wait to see what wonder they will bring. I will order all my plants from this company. Very happy so far. Thank you for making the extra effort to ensure a safe delivery.

  10. 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 😊♥️

  11. Eileen P Forsyth (verified owner)

    I am completely crazy about this gardenia. The size scent and health of the plant are great. I may order a second specimen.

  12. Pamela L Meadows (verified owner)

    First time to receive plants by mail and it worked out great. Plants were in excellent shape upon arrival.


    My first plant by mail. Opened the box to a beautiful, healthy plant with buds. Cant wait for them to open.

  16. Linda K Harrell (verified owner)

    The plants arrived in perfect condition. They were healthy and ready to plant. But them in my little green house for a few days before planting. Can hardly wait for them to start flowering. They are a nice addition to our front yard.

    My plant had buds on it, lush dark green and a very healthy plant, Couldn't be more pleased with my purchase!

  23. Mary (verified owner)

    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?

  24. 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.

  25. 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.

  26. Barbara Bailey (verified owner)

    Amazed by the beauty of this Diamond Spire Gardenia. The leaves already are so beautiful and dark green! Plants arrived big and healthy!

  41. Deirdre Haynes (verified owner)

    Such a unique gardenia. The foliage is gorgeous and its deep color contrasts beautifully with surrounding plants in my garden. It arrived packaged with obvious care and had one bloom. It has since settled into its new home and i look forward to years of showcase from this stunning plant.

    I have ordered many plants. They all arrived healthy. And they have flower buds even early July. The leaves are beautiful and different than other gardenias. They smell good. Very happy.
    Hopefully they will do well in my garden.

    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.

      We spread fertilizer, dirt and love here. 😉 Thank you.

  51. Brenda Briggs (verified owner)

    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.

  52. 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.

  53. Sandra (verified owner)

    Very pleased with the quality of the Diamond Spire gardenias. Received fast delivery and gardenias were very well packaged. Thank you!

  54. maryshields422 (verified owner)

    Arrived healthy. Have remained in original container since Nov. (3mo). Cant wait to plant in early March. So far, no blooms but healthy leaves.

  55. Jerry (verified owner)

    I ordered 2 gardenias and both of them came in wonderful. I can't wait for them to bloom on spring.

  56. Keith (verified owner)

    I love this plant. Its unique look is 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!).

  57. Elizabeth Souther (verified owner)

    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.

  58. S. in MD (verified owner)

    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.

  59. mgauker (verified owner)

    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.
