I'm asking on behalf of a senior neighbor friend who doesn't have a computer. She has a beautiful gardenia plant that she keeps inside. She wants to know if the flowers bloom year round or just a certain time of the year, i.e. spring? Thank you.
While most typically bloom in May or June, there are several varieties that bloom in early summer. This article should help with getting it to bloom if this is an issue for your friend: https://www.gardeningknowhow.com/ornamental/flowers/gardenia/gardenia-care-to-get-a-gardenia-bush-to-bloom.htm
