Frequently Asked Questions about the Cape Jasmine
What does the Cape Jasmine (Gardenia) flower symbolize?
Cape Jasmine symbolizes purity, love, and secret admiration. In the Victorian language of flowers, gifting a Gardenia conveyed deep, sincere feelings that could not be spoken aloud. It also represents refinement, grace, and clarity.
Why are my Gardenia buds falling off before opening?
Bud drop is one of the most common Gardenia problems and is typically caused by sudden changes in temperature, low humidity, inconsistent watering, or moving the plant once buds have formed. Keeping conditions stable and humidity high is key to preventing this.
Is Cape Jasmine the same as Jasmine?
No. Despite sharing "jasmine" in its common name, Cape Jasmine (Gardenia jasminoides) is not a true jasmine. It belongs to the Rubiaceae family, while true jasmines belong to Oleaceae. The name refers to the flower's jasmine-like fragrance, not its botanical relationship.
Are Gardenias toxic to pets?
Yes, Gardenias are considered mildly toxic to cats and dogs. Ingestion can cause symptoms such as mild vomiting, diarrhea, and hives. They should be kept out of reach of pets.
How do I make my Gardenia bloom indoors?
To encourage indoor Gardenia blooming, place the plant in bright indirect light, maintain temperatures around 65–70°F (18–21°C) during the day, ensure high humidity, and feed with an acid-based fertilizer through the growing season. Avoid moving the plant once buds appear.
What month does Cape Jasmine bloom?
Cape Jasmine typically blooms from late spring through summer, peaking between May and August. Some modern cultivars such as 'Veitchii' are repeat bloomers and may flower again in early fall.
