h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

This is a serious question. Primarily because of rabbit damage, I have gradually put more and more Coneflowers into large-ish pots. The downside is that they must be watered regularly, but the upside is that they can live on m rabbit-free porch when they are most vulnerable. They bloom fine there, so they seem to get enough sunlight.

I also have some large planters with somewhat exotic plants and shrubs: a Swamp Milkweed, a Bid's nest Spruce, a dwarf red-twig Dogwood, some lollipop lilies, Daylilies, Potentilla, and one planter that has some unidentifiable plants coming up like crazy. What the heck are they. I can't remember what I planted there. I guess this will be a pleasant mystery. Some day I will figure out what the plants are.

As far as what's growing in the ground, the usual suspects are coming up fine: Jacob's Ladder, Anemones, Virginia Bluebells, White Wood Asters, etc.

No sign of Canada Mayflowers yet. They can grow fine on the lawn at the cemetery where my family is buried. They can do fine in the shade of a white pine/cedar grove. I planted a lot of them last Summer, but they seemed to be either dying or going dormant. I hope they were just dormant, but maybe they are too fussy about where I put them.

More good stuff up: May Apples, Waterleaf, Blue Cohosh, blue Flag lilies, and Labrador violets.

It's much too early to see if any of the milkweed that I planted last year will come up. It's hard to get the right conditions for them. I put the Swamp Milkweek under the eaves so rainfall will keep them as moist as they like to be. Whorled milkweed may or may not take, but if they do, the blossoms will be very nice. I also have some Common Milkweed, most of which went dormant or died late last summer.

It's getting better and better.

The Dogtooth violets are up (I brought them to my yard from my father's yard, and there are more of them every year.

One f the Canada mayflowers actually did come up, so maybe there's still hope.

The peonies are up along the front ramp.

On the north side of my trailer, under the eaves, the Starry Solomon's Plume have come up. The Solomon's seal are also up.

The jack in athe ulpit should make an appearance before long.

It is impressive how many names you know and remember. I can't compete with that at all.
In addition, I have the problem that if I know the name in Danish I usually don't remember what it is called in German and vice versa. (As you may remember I grew up with both languages though chiefly Danish.) The same goes for other things in nature. Fish in particular but not so much animals. Not to the same extent at least.
The bottom line is that I can't help you with the answer to what it is that grows like crazy in your one planter. I just hope it's not trifids

I'm guessing that it's tiger lilies, which will be welcome.
