Sally Scalera on gardenias:
Gardenia cultivars vary considerably in flower size and form, rate of growth, and bloom time and duration. If you’d like to add a gardenia to your landscape here are some varieties to consider:
• Ameii Yoshioka: Flowers of this variety are outstanding, measuring 4 to 5 inches in diameter and have the desirable camellia flower form. Foliage is a brilliant dark green. It is a vigorous grower and produces an abundance of flowers in late spring.
• August Beauty: Distinctive due to its dark green, long pointed leaves and late blooming period. Flowering occurs sporadically during summer but heaviest bloom occurs in late August.
• Belmont: This is a vigorous grower with dark green foliage and large flowers, 4 to 5 inches in diameter, produced throughout much of the growing season.
• Coral Gables: Produces large flowers on compact plants. Dark green foliage with large fragrant flowers which bloom throughout summer months.
• Glazeri: Flower production is heavy on this variety and foliage is medium green color. Peak bloom occurs in April in South Florida.
• Hadley: Flowers are produced in early spring above black green foliage. A vigorous grower with large flowers.
• Miami Supreme: Produces large flowers 4 to 6 inches in diameter above dark green foliage.
• Mystery: A compact, bushy plant with glossy, dark green foliage. Large fragrant flowers are produced during the summer months.
