Callistemon viridiflorus - Hardy Clone



Add to wishlist Remove from wishlist
This clone of an already hardy bottlebrush species has been hardier than the typical offering by a few degrees and personally, our most grievous losses have been by a few degrees. This is likely from a higher and more exposed location in Tasmania as it is also more compact than typical and has handled one winter where it went into single digits. This is the PNW so that sort of thing doesn't last long but still, pretty damned good. Cream flowers and bark that gets white and corky with age and hey, the deer don't like it! Thanks to Ian at Desert Northwest for sharing this one.
