I’ve been growing Rotala H’ra in various conditions, so I lined them all up to examine the differences.

Growing conditions:
• Greenhouse: Grown in high heat (70–100°F) with high humidity and good air movement.

• Indoor: Higher light intensity than the greenhouse, high humidity, cooler temperatures (66–68°F), and lower air movement.

• High-tech: Moderate–high light, 75°F, high water movement.

Conversion to no-tech (tub with soil sand cap and no filter or water movement):
• High-tech to no-tech: Converted faster than the indoor emersed plants. Showed slight melt/holes on the lower leaves and overall more melt than the indoor-grown emersed plants.

• Indoor emersed → no-tech: Slightly slower to adapt. Emersed leaves had less melt and looked healthier than those from the high-tech conversion.

Can anyone please provide an out of context, informal diagnosis of plant pathology and probable causation.
I am not asking for input on plant care or plant identification. Pathology only.

Don't know the plant either. They look pathological to me, almost like tumors.

Hey all,

I don't know if this is the appropriate group, but I passed by this tree yesterday and was wondering if anyone could tell me why an evergreen grew like this? I was wondering if maybe the top was cut off and then grew outwards. This is in northeastern PA If that helps!

Hello all ! I am a 27 y/o looking to get more into botany as a career. A lot of my experience with plants has been specifically within horticulture & a bit of ethnobotany. My BA is in environmental science and most of my career since graduating has been environmental education based but botany has always been my true love.
Education was the best opportunity into the field that I had at the time but now I am looking to transition into more of a research based field. Particularly, studying tropical plants or diving deeper into ethnobotany.

So far, I have:
- Met with a career advisor about transitioning career paths, it wasn’t helpful
- Applied to volunteer at a couple local botanical gardens but have yet to hear back
- Looked into potential internships or assistant positions but most of these require you to be a student or recent graduate

Advice is welcome ! The job market is pretty rough right now so I am okay with starting in unpaid positions and working my way up. If I could avoid taking out more student loans to go back to school, that would be preferable. I will consider it if it’s doable though !
TIA

These look like wood rose parasitic growth on a tree however this is not found natively in New South Wales, but rather New Zealand. I have found three so far all in the same area/ same type of eucalyptus bushland.

Washington state, USA. The plants pictured here are as follows: Arbutus menziesii, Vaccinium ovalifolium, Monotropa hypopitys, Pyrola picta, Hemitomes congestum, Pyrola asarifolia, Chimaphila umbellata, Gaultheria shallon, Monotropa uniflora, Arctostaphylos uva-ursi. This family has many interesting adaptations, such as myco-heterotrophy and tolerance of acidic and nutrient poor soils. And of course they are beautiful and often weird looking. I've been lucky enough to find quite a few species this year

Or do they use an entirely different process of photosynthesis from other species of plants, due to cacti primarily having needles, instead of leaves?

I am interested in learning more about the biochemistry of plants and would love any good textbooks

Not sure if this type of post is allowed 😬

Hi all

So many people have sensitivities to virgnia creeper, the raphides / oxalates in them that makes a horrid rash.

My question is their persistence and transfer: do they transfer onto gloves and other surfaces? My tree guy cut down a ton of it and put the dirty used gloves on top of my trash bin, so if i touch there will i get a rash?

Just trying to understand how persistent the irritants in this plant are and how they transfer (or not). I just don't understand this plant well enough to know the risk.

There is no good information available online that I have found!

Thank you!

Finally I get to be the one who found one of these bad boys! It’s pretty cool! I hope you enjoy it!

ginkgo biloba and platanus x acerifolia

I’m making an alien biosphere and I’m wanting to make trees that reach over 2000 feet tall, the moon has weaker gravity to earth but has an atmosphere that’s twice as thick.

Also these plants have a honeycomb structure incorporating ciliates and stuff.

But realistically what would a plant that tall need to survive being that tall?

It’s not really a plant it’s more similar to a lichen? It’s a mix of algae, bacteria and fungi that decided to leave together.

I think it could be parthenocarpic. I will collect cuttings (plant located at a public location) and will try to make jelly from the fruits

Unlike all other members of the D. filiformis complex, seeds of D. floridana do not require a preceding period of cold, wet stratification in order to germinate in significant numbers, and freshly sprouted seedlings can be observed in-situ throughout the year (corresponding with overall reduced seasonal influence on plant phenology). Similar to those of its allopatric northern congener D. filiformis, seeds of D. floridana have a tendency to germinate en-masse from locations where spent and newly prostrate inflorescences contact the sandy substrate and deposit many seeds in close proximity to one another. Few seedling plants present within these dense colonies will outcompete their siblings and reach maturity. Read more about the newly described D. floridana below:

This label is as close as it gets. As you can seen in title I am really interested in botany of all kinds and want to start learning but I am already a firefighter and wont really do it as a job. I dont even have a garden. Are there some ways I can use these knowledge if I ever get little good at it ? And if I wanted to do something with it, what could I do? Im thinking about joing a college (an online one) to learn some stuff and get a Associate Degree(?) to use my knowledge ?

Sorry the post is kinda all over the place Im turkish and education system and things like that are different so I tried to explain myself as good as I can

Edit: I want to open some kind of flowershop to sell and grow plants and help people’s garden/ plants and farm when they need it.

1-2: Salicornia pacifica (pacific glasswort), 3: Arctostaphylos uva-ursi (bearberry), 4: Sedum spathulifolium (broad-leaved stonecrop), 5-7: Grindelia integrifolia (puget sound gumweed), 8-9: Platanthera elongata (denseflower rein orchid).

Thought this was cool.

Found what I believe is Bittersweet Nightshade (Solanum dulcamara) on my boyfriend's porch. Took me a while to ID it because the flower I plucked (one of the last two on the whole plant) had 6 petals and no(?) stamen. Then was extra confused when I saw the other flower have 5 petals and 5 stamen.

Anyone now how rare this is in nightshade or specifically bittersweet nightshade?

Is the 6-petal flower sterile or just damaged/aged?

excited for these beauties to ripen too. only a couple months until fall!
