As Jane points out these plants are seen to their best with something to clamber over but be careful what you wish for as once they got going here there was no stopping them scrambling over dwarf conifers, climbing up lily stems until the weight bent them over and charging around and up our Betula and Sorbi collections, etc. At the Royal Botanic Gardens in Edinburgh where, amongst other things, they specialise in Chilean plants these roughians are raging through, under, over and up amongst the extensive Chinese specie Rhododendron collection amongst much else besides. I think some of the staff are giving up the will to live. Here despite short growing season at c. 57+ degrees North with minimum - 20 + C there is no stopping them now and I spend much too much time trying to rip them out each Spring and Autumn while in leaf. With a pH of 4.5 they just love it here, any suggestions as to poor winter hardiness are much over stated. No dry periods here, rain, frost or snow like manna from heaven. But for my wife these ????? plants would be out of here now we know what potential menaces if allowed to naturalise. Iain
