California nursery drops invasive plants

John Nitta, owner of High Ranch Nursery in Loomis, Calif., decided to stop growing and selling Cortaderia selloana (pampas grass), Cytisus scoparius (Scotch broom cultivars); Pennisetum setaceum (crimson fountain grass); Hedera spp. (all English and Algerian ivy cultivars); Cotoneaster lacteal (Parney’s cotoneaster); and Sapium sebiferum (Chinese tallow tree).
Nitta wrote on his blog:
Over the years, The California Invasive Plant Council, or IPC, has a definition for “invasive non-native plants that threaten wildlands.” These plants in turn are then classified into ratings of “high,” “moderate,” and “limited.” In studying the council’s listing of “invasive non-native plants that threaten wildlands,” I discovered several on the list that we should not be growing, and made a choice to discontinue six products. I determined these six because of their potential as being invasive to regions that we deliver our products to. Now, when I say that “I determined …” I mean to say that’s it’s strictly a choice of myself as a grower. That’s because I discovered there’s no law that bans me, or any other grower, from producing these plants.
I’m hoping other growers will make these tough choices as well.
