The Jubilation Gardenia, scientifically known as Gardenia jasminoides 'Leeone,' is a specific cultivar of the common gardenia. It is well-regarded for its fragrant white flowers, glossy evergreen foliage, and compact growth habit. Here are some key features and information about the Jubilation Gardenia:

1. Flowers: One of the main attractions of Jubilation Gardenia is its beautiful, white, and highly fragrant flowers. The blooms are typically double or semi-double, creating an elegant appearance. The fragrance is often described as sweet and reminiscent of jasmine.

2. Blooming Period: Jubilation Gardenia tends to bloom from late spring to early summer. The flowering season can extend into early fall in some regions.

3. Foliage: The plant has glossy, dark green leaves that provide an attractive backdrop to the white flowers. The evergreen foliage adds visual interest to the garden throughout the year.

4. Size: Jubilation is a relatively compact gardenia cultivar, usually reaching a mature height and width of around 3 to 4 feet (about 0.9 to 1.2 meters). This makes it suitable for various garden settings, including small gardens, borders, or container planting.

5. Sun Requirements: Like most gardenias, Jubilation prefers to be planted in partial to full sun. However, in hotter climates, some afternoon shade can be beneficial to protect the plant from intense sunlight.

6. Soil and Watering: Gardenias thrive in well-draining, acidic soil. They appreciate consistent moisture, especially during dry periods. Applying a layer of mulch around the base of the plant can help retain soil moisture.

7. Hardiness: Jubilation Gardenia is generally hardy in USDA Hardiness Zones 7 to 10. It may require winter protection in colder climates.

8. Use in Landscaping: Jubilation is often used as a specimen plant, in mass plantings, or as part of foundation plantings. Its compact size and fragrant flowers make it a versatile choice for various garden designs.

9. Pruning: Regular pruning is not always necessary, but if needed, it's best done after the flowering period. This helps shape the plant and encourage bushier growth.

10. Fragrance: The sweet fragrance of the flowers makes Jubilation Gardenia a delightful addition to gardens, patios, or near entryways where the scent can be appreciated.

When cultivating Jubilation Gardenia, it's important to provide the right growing conditions, including well-draining soil, proper sunlight, and regular watering. Additionally, gardenias can benefit from fertilization with an acidic plant fertilizer to support healthy growth and flowering.
