A few suggestions for the pollinator garden: Mountain Mint, Golden Alexanders, and Rattlesnake Master

A friend of mind is experimenting with native plants in her perennial beds and is doing research on how well they perform as host plants for caterpillars and as nectar and pollen sources for pollinators. She claims that the hands-down winner in her garden is Common Mountain Mint (Pycnanthemum virginianum), a beautifully scented native with delicate blooms that is an attractive garden specimen in its own right.

My personal favourite is Golden Alexanders (Zizia aurea), a plant that I became aware of after seeing it in her garden. It’s attractive and is a host plant for black swallowtail butterflies – what’s not to love?

Eryngium has a lot of drawing power for pollinators. Although not native to Ontario, I can vouch for Eryngium agavifolium, also known as Agave-leaved Sea Holly. I worked at Lost Horizons last summer and it was by far the most popular plant in the nursery for bumblebees. It is also a very striking architectural plant for design purposes, though a bit spiky to handle. A close second were some vibrant rose-coloured nativars of Wild Bergamot (Monarda fistulosa); bumblebees would invariably cling and hitch a ride rather than abandon ship when customers brought pots to the cash counter.

The butterfly blame game

Noel Kingsbury recently posted a thought-provoking article about disappearing Monarch butterflies and the rush to blame Monsanta, GMOs, and (overly) intensive agriculture. I loved what he had to say:

I have driven around Iowa a bit… it is the quintessential Midwest farming state, and one where monarch butterfly populations and milkweed have notably fallen. And do I remember roadside to roadside crops? Every patch of ground covered in soya or corn? Er no actually. I seem to recall that like much of the rest of the USA there is an awful lot of mown grass. Vast areas of the stuff in fact. Alongside roads, around houses, offices, churches, shops there seems to be endless acres of this utterly useless vegetation. You can’t eat it, cows can’t eat it, wildlife can’t live on it, and it needs mowing all the time.

2014-monarchwatchNoel may point the finger at North Americans for our love affair with lawns, but I’m going to point it right back at England and a certain influential garden designer in my next post. En garde.
