I think most are plants you might want to keep. #8 is columbine. #5 looks like a weedy plant that grows here, but don't pull it until you get a positive ID--are the stems hairy and bristly? #1 may be Rumex sp. Most of the other plants look very familiar to me, but I can't recall names at this moment.

10 - hibiscus, possibly syriacus
7 - chrysanthemum
6 - mirabilis jalapa (4'o'clocks)
5 - smell a leaf to see if it's alliaria petiolata (garlic mustard)
3 - rudbeckia (black-eyed susan)
2 - same as 7, mums

I thought 2 and 7 looked like mums, but I'm not used to seeing them growing in the ground!

1. Rumex sp. aka Dock
2. Chrysanthemum
3. Rudbeckia
4. Allium sp. (smell it)
5. Geum sp. there are garden worthy and weedy ones - you'll have to wait for a flower
6. Mirabilis jalapa
7. Chrysanthemum
8. Aquilegia vulgaris aka Columbine
9. ?

10. Hibiscus rosa-sinensis (non-hardy)

I think 9 might be Platycodon grandiflorus, Balloon Flower.

Here is a link that might be useful: Google image results

That would be my suggestion for #9 as well.

Flora, I know you're extremely good at this, but about #10 - I'm confused. Wouldn't it be odd for an inexperienced gardener in zone 5 to have a potted tropical hibiscus (and not already know what it is?) H. syriacus is a likely candidate for volunteering in zone 5 and mine always started blooming around the 4th of July, which I loved since they were white with red centers.

Krissipoh, is #10 in a pot? If so, did you put the plant in the pot or did it just show up?

It does seem odd but I assumed the potted Hibiscus was left by the previous owners since it was on the list of what came with the new home.

I was going by the leaf shape and texture (they are more ovate and glossy) plus the way the buds are carried and the appearance of the calyx. I do grow H syriacus in my garden and I am familiar with H rosa-sinensis as a pot plant. So I just said what I thought. But I may be wrong. It will become clear which it is once it blooms.

Maybe someone else can comment.

I you are arguing over the hibiscus it definitely looks to be a tropical one. There are many forms of these.

Not arguing, I never argue over gardening, and prefaced my question with a compliment to Flora's identifying abilities, which are usually correct. Just curious. It's not easy to keep a tropical hibiscus in zone 5. It's interesting sometimes how newbies stumble into success and achieve great results, and wondering if this is one of those stories.
