Ageratum Corymbosum — I must say this is truly one of the most extraordinary shade plants we have come across in many a year Thank you David Feix. It blooms generously all year around here in zone 10 presenting large and glorious fluffy violet-blue flower heads to 6 across like a giant Ageratum and the flowers open from velvety violet bud clusters that are so pretty Most excellent are its exotic velvety leaves which start out greenish but quickly turn a lush and sexy dark purple.

The jade vine, Strongylodon macrobotrys, is native to the Philippines. It's pollinated by bats which may account for its unique flower colour. It's ideal for growing over a pergola where its trusses can hang down and be appreciated at head height. As indicated by its place of origin, it doesn't tolerate cold and will start to be unhappy below about 15℃.
