Plants as magnets for the good and bad

Observing the Joppa Avenue Landscape in Minneapolis, Minnesota, for bees, butterflies, and bunnies
Lounging and observing the laboratory

The occasional sad reality of doing landscape design is that not all landscapes you create will survive long-term. Ownership can change, and maintenance can be spotty. At the very least, you can expect that some plants will die or be less successful than planned due to circumstances outside of your control, and the result will be a landscape different than what you had envisioned. In our case we never could have anticipated the bumper crop of rabbits that seemed to emerge in Minneapolis in the summer of 2009, or how that bumper crop would subside by 2014. Nor could we have anticipated how much the monarch and honeybee populations would dwindle during that same period. Fortunately, we’ve had a living laboratory of sorts in which to observe all of these phenomena long-term and to see what plants are bunny magnets, and which are monarch and bee magnets.

Here is our run-down:

BEE/POLLINATOR MAGNETS
Nepeta x faassenii ‘Walker’s Low’ / Walker’s Low catmint: Blooms for at least a month (reblooms after a mid-summer haircut), with the bees (bumble, honey, and solitary, not to mention hoverflies, hummingbird moths, butterflies, and hummingbirds) on it from sunrise to sunset
Aster oolentangiensis / sky-blue aster: Very good late-summer nectar/pollen source
Solidago speciosa / showy goldenrod: Also an ideal late-summer nectar/pollen source
Diervilla sessilifolia ‘Butterfly’ / Butterfly bush honeysuckle: Bumblebees love the little yellow flowers; lightly cut back after blooming for a second bloom
Perovskia atriplicifolia ‘Longin’ / ‘Longin’ Russian sage: Bees of all varieties love this plant, and it blooms from July virtually til the end of summer
Sedum ‘Autumn Joy’ / Autumn Joy stonecrop: Amazing late-summer nectar/pollen source

MONARCH MAGNETS
Liatris ligulistylis / meadow blazing star: They bloom, and the monarchs come. . . in droves; it’s as simple as that
Eutrochium purpurea / Joe Pye weed: Huge, tall, and full of monarchs once they bloom in July
Verbena bonariensis / Brazilian verbena: An annual that blooms from June (depending on when you plant it) until the end of summer and thus provides a very consistent nectar source for monarchs, which flock to it

RABBIT MAGNETS
Echinacea purpurea / purple coneflower: Numbers dwindled down to almost none by 2013, have replanted new ones and caged them
Panicum virgatum / switchgrass: Ultimately disappeared after two years and space taken over by other plants
Sporobolus heterolepis / prairie dropseed: Initially took a huge hit from the rabbits but now seems to be doing better now that it’s been in the ground longer (maybe rabbits don’t like crusty old grasses?)
Koeleria macrantha / June grass: Suffers some damage by rabbits each year in the spring, becomes less attractive to them by July
Rudbeckia hirta / gloriosa daisy: Numbers dwindled down to almost none by 2012; some that had self-sown in cages around other plants managed to survive, and now the landscape is full of them again (but there are also fewer rabbits now)
Liatris spicata / dense blazing star: Caged them and the rabbits have since kept away; landscape now dense enough that the plant has self-sown here and there, and the seedlings seem to be protected by other plants (that is a very loose hypothesis based on casual observation)
Aster oolentangiensis / sky-blue aster: Some were gnawed down to the ground and died; remaining ones caged and are now thriving and self-sowing with a bit too much aplomb
Liatris ligulistylis / prairie blazing star: A choice meal of rabbits of all shapes and sizes; the plants need cages around them if they are to survive a rabbit’s dinnertime whims

Just to be clear and in layman’s terms: bee and monarch magnets will bring you happiness; rabbit magnets, without the proper protection, will bring you sadness.
