[quote="growin"]lol. Quick on the draw! Resin, have you seen this kinda discolouration on Hibiscus syriacus over there? It's kinda common around here and I thought it was because of a lack of heat.[/quote]
Can't say I've ever noticed it happening, but I don't see many of them. It's all but a greenhouse plant here, the summers are too cold for it outdoors.
