Description

Gold Doubloon is an absolutely incredible variegated Gardenia showing off both stunning foliage and the largest flowers of any of the many varieties in our gardens. In spring new leaves emerge a bright chartreuse that turns to shades of brilliant golden yellow with small patches of deep green at the center. In late spring to early summer extremely large 4 to 5 inch white double flowers fill the garden with heavenly aroma. The leaves are also the largest of any gardenia in our gardens. At only 2 to 3 feet tall and 3 to 4 feet wide, Gold Doubloon is good fit as an accent in smaller garden spaces or containers or in groupings or as a low hedge in landscape borders, home foundation plantings or around outdoor living spaces where the fragrance and stunning flowers and foliage can be enjoyed from close up. The flowers are also great for cutting and display beautifully in your favorite vase.

Landscape & Garden Uses

Growing 2 to 3 feet tall and 3 to 4 feet wide, the Gold Doubloon Gardenia is ideal for use as an accent, in groupings, or as a low hedge in home foundation plantings and landscape borders. Its smaller stature also makes it a nice selection for mid to large size containers. Because they like a break from the midday afternoon sun, and cold northwesterly winter winds, we think gardenias are best planted on the east side of the home or other structures. Needless to say gardenias are a fine addition for sensory gardens and near windows or outdoor living spaces where the sweet fragrance can be enjoyed.

Suggested Spacing: 3 feet apart for solid hedge; 6 feet or more apart for space between plants

Growing Preferences

Gold Doubloon Gardenia is easy to grow in moist but well-drained acidic soil of average fertility and part sun, preferably morning sun and evening with some shade or filtered sun in the mid afternoon hours. We suggest at least 5 hours of direct sunlight for best foliage color and heaviest bloom.As with so many other ornamental plants, constantly soggy or wet soils can cause root rot or other plant diseases. The east side of the home or other tall structure is a perfect spot. USDA Zones: 7a-11 Find Your Zone

Soil pH is important!

To flower their best and maintain deep green foliage color, all Gardenia require an acid to moderately acid soil ranging from 4.5 to 6.0 on the pH scale. Alkaline soil cause yellowing of foliage and flowering will be diminished.

Soil pH is a measurement of the alkalinity or acidity of soil and is measured on a scale of 1-14, with 7 as the neutral mark. Any measurement below 7 indicates acid soil conditions, and anything above 7 indicates alkaline. If you’re unsure about the pH of your soil and whether or not it’s suitable for growing Gardenia it’s a good idea to test the soil pH in the planting area. You can quickly test soil pH with an inexpensive soil pH tester probe or kit.

To lower the pH (make more acid) you can apply Soil Sulfur, Aluminum Sulfate, or Chelated Iron. Adding organic compost to the soil or using compost as mulch can also help to increase acidity and maintain acid soil conditions.
