So. I got a bunch of roses from a store, and there was no new growth on it when I got it. As the flower was starting to wilt, I realized there was fresh green growth sprouting from 2 nodes. If I can properly propagate this, I'd love to, but I don't have the knowledge. The internet only tells me how to propagate from a cutting, but I'm not sure how to apply that to an already sprouting full-flower cutting!!! Help!!

I came across a somewhat-obscure term in an old botany text years ago that I thought was really cool. I’ve since forgotten the word. It was a term for the art/ science of classifying or identifying plants by the way their petals and flower parts are arranged and folded in the unopened bud via cross-section. Not to mislead anyone, but I seem to remember the word started with the letter A. Thanks. 😎

I’m at the Denver botanical gardens with my mom and just saw this plant. Does anyone know why it evolved to have thorns on the leaves like this?

Hi there, I’m a native plant gardener and enthusiast slowly learning more of the botany/ecology side of things. The tl;dr is I have fall blooming natives starting to bloom now and I’m struggling to find info on the topic outside of generalities. For further details see below.

I live close to Lake Erie in ecoregion 83a, eastern Great Lakes lowlands, which is a thin strip along the lake shore. In my garden, and elsewhere within the ecoregion including south of me in 61c, there are fall blooming plants setting blooms now which has me panicking about the implications.

In my garden I had Pycnanthemum virginianum bloom last week, a solid 4-6 weeks early for the area and while my Penstemon digitalis was still blooming. That should never happen. Much worse is Solidago gigantea and flexicaulis, Vernonia gigantea, Symphyotrichum novae-angliae, laeve and lateriflorum. There’s more but you get the idea. Last year the asters were blooming into early October and the goldenrods bloomed in September. Being so close to the lake we have a unique ecoregion here of later springs but also warmer falls which actually extends our growing season. There’s even an aster here that can be found blooming in early November. And again this is happening all over in my area(a small-medium city) including the few natural areas I have near me.

So I’m panicking for the bees in fall. I have cut back most of the plants that were starting to set blooms, and the heat wave we had which may have contributed to them setting blooms is over and replaced by normal day time temps and cool nights in the low 60’s. So, I’m wondering if that combination of factors is likely to stop them from trying to set blooms early again? I do plan on experimenting on the plants that have already bloomed early by dead heading some of them and hoping for additional blooms. I have also found it difficult to find much info on climate change induced flowering times effects on bees in the fall. If anyone can point me in the right direction that would be great. I don’t see how this isn’t going to be an ecological disaster for the bees and other pollinators and I really would like to learn more about it. Thank you!

Hi all, please let me know if this should go to another subreddit.

I research contaminants in food products and I'm interested in bioaccumulation. Mushrooms, kale, and to a lesser extent, spinach tend to accumulate lead from the soil they're planted in. The lead often comes from gasoline spills that make their way into the ground.

I wanted to know what contributes to a plant's bioaccumulation - what makes some plants do it more than others? What plants also will likely have lead, cadmium, or other heavy metals in them due to bioaccumulation?

Are root vegetables a good route to look into?

Thanks a ton in advance!

Found a sweet potato in my house that was sprouting to the point that I decided to try to cultivate the vines. I detached one and put it in water, but left the others attached to the potato and put the whole potato in water. The ones still attached to the potato have purple leaves, but the one I took off and put in water is now growing green leaves. What's causing this? I have to assume there's something either in the potato or not in the potato that causes the leaves to be purple, and the one that's broken off is now either not getting or is now getting that on its own, but a more scientific reason would be appreciated. All I could find online was stuff about light and soil, but neither of these are in soil and they're in the same spot so should be receiving the same amount of light.

Does this plant contain yellow sap in the stem and roots during all it’s growing stages?

Hello r/botany Redditors, I have some information to share.
I made a video on a topic I termed the "World Wide Web," following this link: The Wood Wide Web, incomplete video which I posted on YouTube as an entry video into this global videod-science challenge by the name "Breakthrough Junior Challenge." I rendered my first video, post edits which did not total 2 minutes (the time the competition offered in maximum play) but it was what in prior I anticipated submitting. I had a scene to include to make a total of two minutes in the remainder of the time, it just wasn't uploaded in the initial submission, but I did render a later one, which totalled 2 minutes, here it is linked: The Wood Wide Web, complete video. I'm typing this post, in wonder or thought, as I did make the video to be of some academic spectrum for an audience not specific to the challenge, just people.
Suppose you view the video(s) linked, In that case, I want to ask, what are your thoughts on either or both videos, how engaging might you consider it/them, what of the creative approaches, and how well might you have viewed or understood them considering the time it played plus the video's pace, what I recorded/said during that time, whether it provides any illumination or brings to you any interesting knowledge?
I would be glad for a Redditor's response, from r/botany I do think it'll be nice to get that from individuals or one, from this online community.
Thank you.

Would it be possible to induce fasciation on alot of plants to increase the maximum yield like for example saffron sunflowers tobacco or other

Hi all,

Does anyone know what the authority is on plant taxonomy? I enjoy taxonomy browsers but they sometimes conflict. I frequently like to look up the phylum/class/…/family of a genus, but there seems to be lots of controversy at times.

On that note, does anyone know what the deal is with Magnoliophyta vs Tracheophyta ? It seems Magnoliophyta is the phylum of flowering plants, but Tracheophyta is the phylum of vascular plants with a subphylum Angiospermae for flowering plants. Class level and down they seem to be the same. Is Tracheophyta more up to date?

I've been growing pineapple plants for about 2 years. Now that I'm getting fruits all of my plants have crowns expect one. It's not a problem I'm just highly confused and in disbelief. I live in the back of a preserve so there are deers and some bears but there's no sign of any damage or anything. I don't really know the species of the plant I just know that I cut the heads off of some pineapples at my nearest Walmart and planted them. Any info will help.

This seems like a pedantic question but I’m hung up on it 😆 when a plant forms a flower and it opens, that’s it blossoming or blooming.

So take a sunflower that only opens once and stays open, it only blooms/blossoms once.

A morning glory flower opens and closes periodically, is each time it opens considered blooming? Or does the flower opening the first time count as the only “bloom?”

If you have sources to cite, that would also be appreciated 😆😅

I'm looking for any bibliography that helps with identifying arecaceae plants using the seed. Anything helps, books, papers, keys

I’d really love to know more about south east asia plants and migration of those plants (primarily Vietnam, Cambodia, Laos and China)

How long ago did the two diverge and how being as they are on separate continents?

Hello everyone!

I'm looking for photographs of flowers cut in half, or longitudinal cross section / anatomy drawings of flowers. I need them as references for a couple of 3d models that I need to make.
The exact flowers I need are:

1. Pot Marigold (scientific name: Calendula officinalis)
2. Common Sunflower (scientific name: Helianthus annuus)
3. Babchi / Bakuchi (scientific name: Psoralea corylifolia)
4. Rosebay Willowherb (scientific name: Epilobium Angustifolium)

Does anyone know of any online resources or books where I could find that information?

(I included a photo and a link as examples)

Thank you in advance! :-)

I'm a computer science student working on my final year project, and I've chosen to create a machine learning model for flower classification, similar to the well-known iris classification problem. I'm looking for a flower species or genus that has a low number of species and is easily distinguishable by appearance. However, I'm not very familiar biology , botany , flowers. Could you suggest some common flowers that would be suitable for my project?

Thank you in advance for your help!

I read that because many grasses are C4, they should be relatively more abundant than forbs under a low CO2 environment. Is this correct?

I have a pear tree covered in rush, and I want to defoliate it. I am hoping it will make new leaves this year, but I am worried about lopping off all the leaves. Ive thought about using abscisic acid to simulate fall senescence but I am not sure if the tree will store its nutrients and energy in buds for next year or not. Anyone know?

I would like to write a story where characters are using real science-based "herbalism". I cant google out any kind of online database that contain central-european flora and I could search f.e. for a herb that would be part of ointment to help stop bleeding. Or a plant that help curing dysenthery etc. Can someone direct me to Online source of such? Many thanks.
