|Insect feeding can cause the misshapen leaves. It's possible that if you do not see insects (aphids, thrips, etc.) that they damaged the leaf buds as they were emerging and then went on to other parts of the landscape. The damage won't show up for a week or two after they've left. About the only other possibility for the damage is that the roots suffered some injury during the cold spell and simply are not able to produce healthy stems and leaves. The cure for this is to keep your plant as healthy as possible this summer so it can develop a healthy root system. Next spring the growth should be normal. Best wishes with your hibiscus.
