Why won't it flower? Planted three years ago. Grows like crazy and winds itself around the trellis. In full sun. Has never flowered.

There are various kinds of honeysuckle. Do you know which yours is?

I don't know why yours isn't blooming but when I have a plant that should be blooming... it's the right time of year, it's old enough, looks healthy, but just isn't blooming, banana water almost always makes it bloom. Pureé a banana peel or whole banana if you feel luxurious and dilute that in your watering can, water the soil all around the plant with the banana water. If you try it, please let me know your results.

No, I don't know the variety. But I just did the banana tea application! I'm excited to see what happens. Thanks!

I have native coral honeysuckle, blooms all over even in shade, yours just may need to grow another year.

Happy to suggest. ; )
