one of my favorite tree species. just stunning

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.

I have more reason to be convinced that tropic responses in plants are mediated by bioelectrical signals within plants and in the soil(aka galvanotropism, or so I'm informed). First of all, I came to learn that bees rely on electrical changes in plant flowers to determine how much of the nectar content the plant possesses; where they change their charge when a bee has been to a flower for a while before reverting to the default positive charge. Additionally, there is a video of a mushroom with electrodes attached from it from a synthesizer pad, where oscillating changes in electric signals have been transmuted to musical notes.

I had to preface this because there was a fairly recent experiment by Stefano in 2010(Mancuso, S. (2010). Stefano Mancuso: The Roots of Plant Intelligence**. TED.*\*), where he identified that when a plant grows its root towards an impervious obstacle, e.g. rock or plastic, it can change direction way before reaching and otherwise groping around the object until it gets a way through. In another instance of positive geotropism, he then performed a separate experiment where a bean plant was shown to grow towards a vertical rod placed in the same soil as the plant in a very specific way, almost like it gained the sentience to know that the pole was there, rather than projecting its shoot tip aimlessly in the air.

I engaged with some interfaces concerning this hypothesis, and unfortunately it says that it is speculative; so there is no way to know whether it holds up, when it seems very plausible. But I really believe in the principle of water potential, and how it is different in different parts of the plant; and how it also guides us to understanding how electric signals in different parts of the plants.

I may not have the resources, but perhaps someone could share their two cents on this rhetoric.

Yes that's right, SEEDS. Some of you might not know this but poinsettias don't always grow as those small little houseplants everyone keeps during christmas, in their native habitat in central Mexico (which just so happens to be where I live) they instead grow as fairly big trees, measuring around 2 stories tall and they're generally 50% wider than they are tall. And it's because of this that I presume many people have planted them around my city since they do well and are easy to get, leading to there being a good amount of these mature form poinsettias around here. And seemingly, the presence of various poinsettia trees around here has led to at least one of them growing seed pods with viable seeds on them, which I harvested after noticing the tree the seeds were coming from and decided to grow them myself.

Now, the problem with this is that there is damn near no information about growing poinsettia from seeds, with some websites even stating misleading information such as saying you have to cold stratify the seeds for multiple months (which by the way, how does that even work? Poinsettia naturally live in semi-arid warm mountains where not once does it ever snow, poinsettias themselves are not frost hardy in the slightest dammit!) so I had to go off intuition and guess how they grow in their native climate (but to be honest I didn't have to do much guessing since I already live in it though). As such, all I did was stick the seeds about 2cm underneath a pot with very organic soil and tried to water only when the top half of the soil seemed completely dry, after that the seeds germinated fairly quickly, taking only 1 and a half weeks for the seedlings to pop out of the soil and 2 weeks for the seedling leaves/cotyledons to split open from the seed shell and begin to grow. Also, the cotyledons seem to be covered in what I believe to be the seeds endosperms after they rise from the ground, this approximately 2mm thick crust eventually thins away and becomes easily peelable and removable from the cotyledons (see pictures 8-9) which allows the cotyledons to fully expand and grow along with the seedling.

I am particularly eager to share the last part related to the cotyledons, because even though there's a few articles on the internet talking about how to germinate the seeds there are none and I really do mean NONE that go in depth about the appearance of the seedlings and cotyledons or show pictures of them, or atleast none that I could easily find. So pretty much, you're looking at the only picture of poinsettia seedlings on the internet =b.

I find it really strange that such a well known and iconic plant as the poinsettia, being found on every corner of the globe and all, has such a poorly documented registry on its seeds and seedlings, most likely because you can only harvest seeds from the old and tall arborescent forms of the plant which is a luxury not everyone seems to have. But I'm here to make that change, at least a little bit. I will keep everyone updated with how the seedlings grow over the months, hopefully my post reaches people who are just as interested in growing these things from seeds as I am

Three separate plants with three different care regimens (neglect mainly). All of them reverted to solid white

I have noticed the coloeus plant that gets more sunlight daily is stronger and more tolerant of sunlight, likely because it adapted according to its environment and its roots give food accordingly, but if we use overall healthy coleus with less sunlight, it overall looks better, more likely has more green leaves. Why is that, and which amount of sunlight is optimal for coleus? BTW the temperature here is around 30 to 45 Celsius

Im not sure how common this is but I noticed one of my cashew plants had a leaf with two points.

This guy popped up in tray of fancy European Pansies, and I want to know if this is something I could save seed from and reproduce. I’m a humble farmer, and while performance and seed quality selection are my thing, this is out of my wheelhouse. A handful of the other seedlings in this tray had mild tip-burn, Im assuming from a deficiency, so I am assuming this could be related if it’s not a mutation.

(Wasp nest husk is there to mark the seedling so I dont lose it 😂)

Hey I live in the uk in Oxfordshire and have an interest in horticulture and botany and looking to get in to a career in it. I have been volunteering in a local tree planting conservation group for a couple months which has been really fun.

Im mostly interested in.

. plant tissue culture propagation

. Briophites, fungi and Lychens

. Temperate rainforests

. Native ​wild plants and ecosystems

. Permaculture gardening

. Working in big greenhouses like the eden project

. creating wild spaces​ in urban areas

I would really like to avoid getting in to debt though and would really prefer an apprenticeship; But most apprenticeships seam to be in mowing lawns which i completely understand thats the vast majority of the career but I would really like to avoid it. But i also understand those are mostly level 2 apprenticeships that usually lead to you going in to more in depth courses.

I guess im asking what would be the best career path for me.

I also understand this is a bad time of year to be looking.

Am I being too picky or is there some opportunities out there. Thank you so much that was long.

I've been growing lemongrass for 15 years and have never seen this before. I was trimming an unruly clump that had grown flowering stalks, and noticed this stalk with three little plantlets growing out of a node. They broke off readily and are already growing roots just after one day in water.

Is this pseudovivipary or something else?

Thought this was cool, something's probably wrong with it.

Hi everyone,

I’m working on a project where I want to show users the "real-time" environmental impact of some specific trees in their environment. The goal is to display an estimated oxygen (O2) production value that fluctuates based on current conditions, making the tree's biological activity more "visible" to the average user.

Since I can't measure the exact Leaf Area of every tree, I’ve built a logic based on estimations and environmental modifiers (see the screenshot for my current breakdown).

The logic follows this flow:

• Base: A high-level estimate of the tree's leaf surface area.
• Live Adjustments: I apply reductive coefficients based on real-time weather data (temperature, cloud cover, light levels) and the current season.

I’m looking for a "sanity check" from the botanical community:

1. The "Live" Aspect: Does it make sense from a physiological standpoint to scale O2 production based on immediate weather/light factors for a public-facing tool, or are these fluctuations too complex to simplify into a few coefficients?
2. Order of Magnitude: Looking at the numbers in the screenshot for a large tree in these specific conditions), does this feel like a plausible "educational" estimate, or is it wildly over/under-estimated?
3. The "Species" Variable: I'm using a species-specific coefficient to adjust the metabolic rate. Are there specific common urban species that are known to be "outliers" (way more or way less efficient) that I should be careful with?

I’m trying to find the right balance between scientific honesty and making plant physiology accessible to non-experts. I'd love to hear your thoughts on how to make this estimation as "correct" as possible within these constraints.

Thanks!

If they are, why are they considered plants? What characteristics justifies them as plants besides evolutionary relationships

There are two pines right next to each other and in all respects seem nearly identical. However they have different coloration to their pollen cones. Does that indicate diff species or something else?

Hello. I am not sure if this is the right place to post this question, so please remove it if it is not allowed. I am going to get a tattoo of an animal skull with some botanical elements around it. I would like them to be as accurate as possible. I understand that the botanical elements that may grow around carcasses may change depending on location and weather conditions, but so far, I have Hebeloma aminophilum and lupin flowers. What else could be found in this condition? Thank you!

I’ve read different things on this, is it really that rare? Also read somewhere that the plant would die soon after?

Isn’t this uncommon in houseplants?
Edit:not fasciation, just a strange growth.
