Glowing mystery

Here’s a snippet of a photo I shot this summer:

What is this mysterious glowing object?  (I did not manipulate this photo in any way other than to crop it) Answer Monday!

By the way, Lynn asked if we could do a posting on how to make our landscapes more wildlife friendly.  We’re doing even better than a posting – we’re doing a whole week’s worth of blogs on the topic!  Thanks for the suggestion – and the rest of you feel free to suggest topics as well.

Tricky tricolor leaf

Well, this was a tricky puzzle! Here’s a more complete picture of this interesting plant:

This, believe it or not, is a weigela – specifically, a patented cultivar named Kolmagira. You can see part of a tag in the lower left part of this photo:

 

As the patent description reads, this shrub possesses “…yellow green and dark green variegated leaves with purple-colored margins…”

Some of you guessed that the leaves might be variegated due to fall senescence, or disease, or drought stress – all very good guesses. And now I’m going to reveal one of my biases (yes, I am opinionated!  I know you’re surprised!)

I dislike these types of cultivars because they look environmentally stressed and/or diseased. I’m a plant stress physiologist by training, and that’s just the way I look at abnormal leaf coloration. And on a more aesthetic note, do our gardens really need these tarted-up plants?  Let’s discuss it!

Autumn leaf? Or is it?

It’s that time of year – leaves are turning all shades of yellow, orange, and red – so I thought I’d use this leaf for today’s puzzle:

I had to photoshop this extensively so it’s a little rough looking.  But it does have a toothed margin.

So – is this an example of autumnal coloration?  Or something else?  Extra bonus points if you can identify the genus of this plant.

Answers and another photo on Monday!

When You Gotta Go, Go Green

Here’s a bit of the fact-filled, intrepid reporting we at Garden Professors are pleased to provide.

Just back from a visit/droolfest to Pennsylvania’s "Golden Triangle" of horticulture: Swarthmore’s Scott Arboretum, Chanticleer, and Longwood Gardens. 

At closing time on Saturday, I was wandering through the cavernous halls of the Longwood conservatory, looking for either my travel companion John Greenlee (Mr. American Meadow Garden), or the restroom.  Found one, then followed the signs to the other…

Whoa.

And it keeps going, way on around the bend.

Unveiled just a week prior, the green wall system was designed by GSky Plant Systems. At a little over 4,000 square feet with 47,000 plants, it’s now the largest green wall in North America. 

The modular panel system is very clever:

Plants are held in place by a geotextile surrounding a fiber substrate. Computer-controlled drip irrigation is woven throughout the entire structure.

Except for the glass ceiling, the corridor is subterranean. Perhaps because it was closing time and mostly empty, we found it just a tiny bit unsettling. John flailed about, muttering something like "Soylent Green is people!" 

Anyhoo, it was very grand and inspiring. In case you’re wondering what was behind all those shiny steel doors: 

 

Folks, you can’t get this kind of in-depth information on just ANY garden blog…

Mystery shoot identified (no big surprise, apparently)

Readers were too smart this week!  Yes indeed, this is a coconut, improbably found at a Home Depot in Seattle:

Unfortunately, in our climate this can only be an indoors plant, and even a McMansion won’t be able to contain it for long.

Gold stars to Ed, Deb, John, Jess, Jimbo and Ginny!

Where the Money Comes From

After reading Linda’s excellent post yesterday I got to thinking about all of the discussions I have had over the years with people who didn’t know or understand where we (and by we, I mean my research group) got the money to do the work which we do.  Oh, they thought they knew, but they were usually way, way off.  So here I’m going to give you a terribly over-simplified version of the types of money that a professor can get to conduct the research that they want to conduct.  This rundown will be different from professor to professor and institution to institution of course, but the basics will be about the same. 

#1 An Endowment:  This is gold – the best thing there is in terms of funding.   An endowment is a large sum of money in an account which earns interest, and that interest can be used by the researcher in almost any way they want (as it relates to their research of course).  Few professors have endowments for their research (though quite a number have some percentage of their salary covered by an endowment).  As you might expect, endowments may yield anywhere from a few thousand to a few hundred thousand dollars depending on a number of factors.  My position does not currently have an endowment associated with it.

#2 Hard funding from the University (actually state or federal funding, but it feeds through the University system):   This type of funding is great.  It isn’t as flexible as an endowment, but it is still usually quite flexible (as long as the money is used for a project which the professor was hired to do —  an English professor couldn’t use hard funding to study how container growing affects daffodils).  The word “Hard” implies that the funding is available at a more or less constant level year after year, but recently it has been volatile.  If a University is suffering because of cutbacks, hard funding is in danger.   When I came to Minnesota I had quite a bit of hard funding – basically enough for a full time technician.  Now my hard funding covers a fraction of that.

#3 Gifts:  Gifts are one time presents of money.  Gifts are very flexible, and always greatly appreciated, but not recurring.  I have received gifts from various people and organizations ranging from a few hundred dollars up to $15,000 (sounds like a lot, but if you’re using it to pay a salary it doesn’t last long).

#4 Government Grant:  Government grants (I’m going to be liberal in my definition of Government grants – they can be anything from NSF and USDA grants to grants from cities or parks) are great, but they may only be used on research, teaching, or extension that the grant was given for.  This money may or may not be recurring over many years.  These grants can be prestigious and important (think NSF), but they’re also a tremendous amount of work and very competitive.  I have written and been on these grants and they are currently how I fund most of my research on things such as elm selection and preferred boulevard trees (my grants are from local and city entities rather than NSF or USDA, but the idea is the same).

 #5 Industry Grant:  An industry grant is similar to a Government Grant except that it is given by an industry group, such as the Minnesota Turf and Grounds Foundation, or by a particular company, such as Bayer.  Industry groups are a preferred source of income, but money from chemical companies, and other independent companies, does have a little bit of a stigma associated with it – it feels like you’re doing something to benefit one company instead of society as a whole.  Chemical company money is not sneered at, but often you do have to conduct research that may not be at the top of your priority list (though if a professor doesn’t care about the research at all then usually they won’t do it). If I can make ends meet in terms of paying my employees by treating some buckthorn with triclopyr, then yes, I will do it.  I have never taken a large sum from an independent firm, but I have certainly taken money and provided the research agreed upon.   I would go so far as to say that most professors in the agricultural sciences have.  For some it provides the bulk of their research dollars.

I’d like to conclude by saying that, in the case of dollars from chemical companies, I don’t personally know of any researcher who has purposefully falsified, failed to report, skewed, or selectively excluded data to make the chemical company happier with the results.  Doing so would ultimately just make that researcher (and the chemical company) look like an idiot.  I have personally given data to chemical companies which shows that their stuff doesn’t work that well – they don’t like it, but they appreciate it – marketing something that doesn’t work isn’t good for anyone.  I do know of a case where a researcher proposed a study to a large chemical company which would examine unseen dangers of a particular pesticide and was turned down – this was disappointing to me.  I think that many companies feel that they have a duty to seek out obvious dangers and that the government has a responsibility to fund research investigating unseen or unlikely dangers – but that’s just my own opinion.

Pruning perpetrators

Just when I thought I had you all fooled, Judy slipped in at the last minute with the correct answer – the “pruners” in question are deer:

The pruning ends when the deer can’t stretch any further, giving the tree its odd bell-shaped crown:

This is also a great demonstration of how pruning stimulates new growth – you can see the dense healthy growth at the base of the “bell,” even though this part of the crown normally would be much sparser.

Thanks for all the guesses!

Fungal fun continues!

The comments on Friday’s puzzle have certainly been imaginative!  (Tribbles indeed!)  But this weekend nature cooperated to give me some more information.

My little fungus family expanded over the weekend.  As this photo shows, we definitely have a mushroom-type fungus:

Looking at a young member, you can see what look like stalked spores emerging from the gills:

And the edges of the mushroom curl upwards as the spore mass grows

until we end up with the black furry ball shown on Friday:

So the discussion continues:  What the heck is this?  Is it one species, or is there another species that’s emerging from the gills of the first?
