So if you haven't seen my last post I found a mature poinsettia tree with seeds near me and thought I'd give it a shot to grow some, being that there is almost zero information related to poinsettia seedlings on English. And well, I'm happy to announce the seedlings turn 1 week old today! So far they're doing very good, they're growing really fast, even far faster than I expected, and they've got some huge seedling leaves as well as some true leaves that are seemingly going to grow pretty big as well. The seedling leaves at the time of me posting this are around 4 centimeters wide on all sides, and I can definitely say I didn't expect them to have seedling leaves this large, but I'll have to let y'all know if they grow any larger than they are now.

All and all the seedlings are doing great, hopefully I can keep them for another year and get them to flower to see what might change with them, that's all for now, bye!

Sorry it’s hard to see from the photos but for scale I am about 6’4 and I estimate this specimen to be about 10-12 feet tall. Additionally all surrounding C. nuttallii were in the usual 4-7 foot range. Im not very well versed on if this is an unusual find I know they can get quite big but I’ve never seen one genuinely tower over me like this. Would love any insight in the comments.

In the New Forest (UK) this month and under one tree about 25% of the oak seedlings all had gorgeous variegation, some were greener than others and looked like they were more likely to survive. How common is this and has anyone ever seen a full grown variegated oak?

I've noticed the new growth does this when exposed to the sun. The leaves slowly fold as they get sun like in the images. Does anyone know what causes this?

I'm not asking about plant care, just curious about what actually causes this.

Not an ID request, but I believe I have found some silverleaf nightshade (Solanum elaeagnifolium). When I search for public images of it, I get quite a few results for similar-looking nightshades, but the name of the species sometimes changes over the years. For example, Solanum astroites seems to have become Solanum bonariense (but I'm not sure).

The question: How can I find out if there are any historical nomenclatures used for Solanum elaeagnifolium? Is there a database of taxonomic changes?

Bonjour.

Est-ce de l'ambroisie ?

I am doing a job on an abandoned farm in the Mississippi Delta and it's beautiful how the plants have begun to take over and the birds and insects have all moved back in. It's literally a symphony and the farm has only been abandoned for a couple of years. Active farms are eerily silent.

may just be me, but i think they're so amazing up close

My Orchid bloomed with 2 flowers emerging from a single stem and bud. Hard to get pictures because they faced opposite directions.

There's this meadow on my campus that is left unmowed for the ecological benefit and among all the normal looking plants (also many others of the same species) there's this stunning individual. I think it is Leucanthemum sp., probably Leucanthemum ircutianum. Is this an instance of a naturally occuring mutation? I'll come again in a few days to see if it has started blooming!

With a little help from a clear plastic cup and later a 10” clear pot I’ll be watching this little peanut grow from seed and hopefully set some seeds.

There’s already some neat stuff going on. The roots are growing almost visibly, and I should start seeing root hairs today or tomorrow.

The way peanuts grow is neat. After pollination the old flower stalk is pushed down into the soil, called pegging, where then nut will grow in somewhat safety. I’m looking forward to this.

Is there a toxin difference between “wild cherry species” and the “commercial cherry tree saplings and seedlings?”

Hello, I live in the Willamette valley in Oregon. I have sheep and I want to learn more about “wild cherry,” wilted leaf poisoning in livestock. We lost two young lambs simultaneously from an unknown plant toxin. According to the veterinarian, it was an extremely rare occurrence for twin 16 day old lambs to die within an hour of each other without trauma, which leads to a poisoning. There are “wild cherry” trees alongside our fence line, but the species is genetically connected to dispersed commercial cherry trees. My guess is that the lambs may have found and ate sapling leaves.

For miles, our local “wild” cherry trees come from commercial cherry seed droppings due to a “long gone bing cherry farm” in our region. I am trying to understand the toxin difference between the known toxic leaves of “wild cherry tree species” and dispersed commercial “wild cherry trees.” The cherry trees lining our fence do not truly resemble Prunus serotina, virginiana, emarginata, or pensylvanica, but, the commercial cherry tree seedlings appear to revert into a smaller fruited “wild” cherry. Knowing that they have been naturally dispersed by seed over decades, can a bing cherry tree revert back to a true “wild cherry tree?” Could these versions of “wild cherry” convert and carry significant toxins?

In 25 yrs of sheep herding and hundreds of lambings, we have never experienced a sudden unexplainable death of healthy lambs in our flock.
I’d love to talk with a plant toxicologist, or veterinary toxicologist about this.
Thank you.

This is a hardwood floodplain. Right now the stream is pretty wide, but by the end of the summer it will be mostly dried up. Found lots of Canadian meadow garlic (smelled really tasty), lily of the valley, marsh violet, toothwort and much more. It was cold and raining but I had made up my mind and nothing was going to stop me from seeing some plants!

Not sure on the ID of the first one but I believe the rest are woolly, smooth yellow, Labrador, and northern bog. All from wisco
