It's almost that time of year again to start working in the garden. Here is my rant about The Home Depot, Lowe's, and all the big box stores. Please stop buying your plants at these establishments as they all still carry non-native, awful ground covers like creeping Jenny, English ivy, pachysandra, and vinca. Even more absurd to me is how they are still selling Bishop's weed (goutweed). This plant is evil and should be on the 'Do Not Sell' list (Burrell, Marinelli, Harper-Lore, 2011). Some are carrying the so-called sterile cultivars. Please do not buy cultivars of these awful invasive plants. My last bit, if you go to a garden center and they have a native plant section you have to walk by the fertilizers, herbicides, and invasive plants to find them. Always question the motives of that garden center!
Now that I have that off my chest, let's talk about alternative native ground covers (Burell, Marinelli, Harper-Lore, 2011) to use instead of non-native, awful varieties.
Please do not use the following ground covers:
Bishop's Weed aka Goutweed (Aegopodium podagraria)
Bugleweed (Ajuga species and cultivars)
Chameleon Plant (Houttuynia cordata) - how is this not on either list for NYS?
Creeping Jenny (Lysimachia nummularia and cultivars)
Spotted Dead-nettle (Lamium maculatum and cultivars)
Yellow Archangel (Lamiastrum galeobdolon and cultivars)
Instead of planting the following evergreen invasive/aggressive non-native ground covers:
Creeping Euonymus (Euonymus fortunei) (NYSDEC, 2014)
English Ivy (Hedera helix)
Lily-turf (Liriope spicata, Liriope muscari and cultivars)
Pachysandra aka Japanese Spurge (Pachysandra terminalis and cultivars)
Periwinkle/Myrtle (Vinca minor, Vinca major, and cultivars)
Plant these native semi-evergreen and evergreen ground covers instead:
