Delores I was looking at your beautiful hibiscus and noticed the leaves - They are completely different in shape and texture to the ones around here. I've got a red one that hasn't flowered since April 2020 (my brother accidentally gave it a boy prune and it's yet to recover...) I dug around and found a photo. Check out the broad, tear-drop shaped leaves:

This is my oddball with the weird leaves. The other two look like yours. One is a giant, the other just a Hardy. The giant is as tall as me - that’s not saying much as people go, but it’s a right tall flower lol
