We may have to get used to a new name for our out of control R. ponticum. A new study says that our ‘wild’ Rhodo in this country is such a mish mash of hybrids that it should be called Rhododendron x superponticum.

See article http://www.rhs.org.uk/Plants/RHS-Publications/Journals/Hanburyana/Hanburyan-issues/Volume-5–June-2011 and click on the ‘naturalised rhododendrons’ link.

Quote: “Differs from wild R. ponticum in that it is

extremely vigorous and invasive and has a wider range of corolla and

corolla-spot colour”.
