My Harlequin Glory bower has never had any flowers.

Question

I dug up two young plants. I gave my mother one and hers has bloomed both years, but mine hasn’t. I fertilize 3 times a year and it grows, but, no blooms. What else can I do to get it to flower?

Answer 1

First, check your growing conditions based on the info in these articles:

The plant blooms best in full sun. Also, I'm wondering if it is getting too much fertilizer. Try adding compost in the spring instead of fertilizer. None of the articles I read mention adding fertilizer, but it likes "moist, fertile soil."
