weed or plant?

corrimal, Australia

Does anyone know what this plant is? It sprouted up in about 2 weeks.

looks like some type of amaranth?

mid central, FL(Zone 9a)

yes, it's a plant and yes, it's a weed! (imho)

Magnolia, TX(Zone 8b)

Not good at Australian weed plants, looks like it was planted. It needs more height and flowers would be a plus- u guys say amaranth and I thot nightshade. No reason,just tired...

Adelaide, Australia(Zone 10a)

I'm also inclined more towards Amaranth. The Solanum (Nightshade) weed seen most commonly here is Solanum nigrum which has flatter leaves with smoother margins and is a much darker looking plant overall. See http://www.weeds.org.au/cgi-bin/weedident.cgi?tpl=plant.tpl&state=nsw&s=®ion=aa&card=H74

Our commonest weedy Amaranth is usually A. viridis, but this plant looks different. See http://foragersyear.wordpress.com/2012/03/16/amaranth-the-perfect-weed/

It could even be an escapee Amarathus caudatus, but those look different again http://davesgarden.com/guides/pf/showimage/112177/

What ever it is, it won't do any harm to leave the plants a little longer so you can come back and show us pictures of the flowers when they develop.

Maybe some Nicandra? I am not too sure. Kinda looks like my N. physalodes
Or some other kind.

Keaau, HI

It looks like the Nicandra physalodes that grows in Hawai'i.

I'm letting it grow until it sprouts flowers or something. I've only just started gardening so I literally have no idea about plants lol. I will post more pics when it does something exciting. I am also going through plant list trying to find it.

Chloeh, does this plant have a square stem? I'm looking into Lamiaceae, maybe catnip...?

corrimal, Australia

It's a squarish stem with vertical ridges on it.

Anne Arundel,, MD(Zone 7b)

doesn't strike me as catnip, and catnip is opposite leafed, right/ this seems not to be, though it's hard to say for sure.

Cape Coral, FL

coleus? or something similar..? Have you tasted them?

Anne Arundel,, MD(Zone 7b)

coleus= opposite leaves in obvious pairs

mid central, FL(Zone 9a)

looks like pigweed to me.

Cross Timbers, MO(Zone 6a)

I'm thinking maybe Lunaria?

Anne Arundel,, MD(Zone 7b)

Plant on the right just looks 'unpaired' to me so I'm leaning to pigweed or some other Amaranth.

(Zone 7a)

I'm leaning towards an Amaranth of some kind, too.

And I do NOT recommend tasting any plant until it's IDed.

Cross Timbers, MO(Zone 6a)

I have looked at several amaranths here at DG and elsewhere, and I have a few of my own.The veination does not compare to this plant. Both are pinnate, but this plant has smaller, reticulate veins causing puckering. The Amaranth clearly does not. Sorry, but I just don't think it's an Amaranth.

And tasting unknown plants could be hazardous to your health!

They ended up growing about 40 cm tall but never sprouted flowers or anything and then died. I still have no idea what they are. I think my kids must have picked up some seeds or something whilst we were out. I always tell them to drop any plant stuff they collected in the garden.
I hope one day someone figures out what it was because it's killing me not knowing lol.

I went up and looked at the picture (which still strikes me as a pigweed or amaranth) and I am fascinated by those two long skinny 'cones' laying on the left side. DO you know what they are?

Adelaide, Australia(Zone 10a)

Dead bits of Norfolk Island Pine branches. I bet! (Araucaria heterophylla) See this photo: http://davesgarden.com/guides/pf/showimage/271734/ Note that the leaves tend to curl up more closely as they dry out. Maybe chloeh can tell us if she's got a nearby Norfolk? There must be a few thousand of them in Adelaide alone: http://www.aroundtheregion.com/adelaide/norfolk-pines-at-glenelg/

Ciao, KK.

THanks, KK. One 'man's' mulch is another 'man's' fascinating bit of nature...

ROSLINDALE, MA

Could it be a Physalis? P. alkekengi, maybe? (That's a wild guess, I don't know your Australian flora)

Cross Timbers, MO(Zone 6a)

coriaceous, I think you hit the nail on the head. Physalis indeed! But maybe Husk Tomato Physalis pubescens var. integrifoliaI? I think the two pictures are identical. Ooh your're good!

I have a bunch of physalis in my yard now this time of year, and they look nearly identical!
