Calin--love your pictures. I see your gardening interests are varied. Lovely Hibiscus. I had both red and white I started from cuttings. The white was huge--like your white one --a good 24-25 cm. Bloomed in late August until frost here. They did well for about 15 years. I should have started more cuttings to keep a run of newer plants but my interest in lilies took over and that 'trumped' everything and in the process I lost them both. Does your soil run a little on the alkaline side? I noticed the pink Hydranga.
