Trillium 2012

[cohan]

Looking for advice on soil for Trilliums- as I mentioned, I think its T erectum and grandiflorum seedlings I have-- how much organic material should the soil have, and what about issues of drainage, moisture retention? Most of my woodland plantings will be at the moister end of the property, and natural soils are a fairly thin layer of humus over a clayey soil (most perennials etc do fine in our soil unamended) but I am also working on some low berms in the area that are part soil part leaf/grass compost, and developing another bed on a site that was used for dumping leaves, grass, sticks and bits of wood, a bit of old potting soil etc (and some junk like old pots and plastic I have to pick out!) which I think will end up being somewhat raised and quite loose and humusy....

Mark, T lancifolium is a strange one - very uncommon shape! I like it

Here is some correspondence about Trillium erectum Beige

it seems to be not a valid name
but just used in the commerce

I took away the .nl against spambots

 I agree, numerous references point to cultivars in commercial sale, however, scientific documentation for “Trillium erectum f. Beige“ is elusive

I can't recall ever hearing of that name being published as a valid name. However I haven't done a real literature search for that specific epithet.

Addition to Trillium erectum Beige

This mail just arrived

Roland

In my earlier post, I may have given the impression that I was just remembering that I bought T. erectum beige from Arrowhead Alpines (AA) in 1995.  But this is directly from a copy of their 1995 catalog:

"TRILLIUM ERECTUM BEIGE"

A fairly unusual erectum that may have some hybrid parentage

Considering that the price for three of these plants was $6.00 in 1995 (inexpensive even for that time),  I am guessing it possible that AA obtained them from Tennessee collections and, per John Lonsdale's observation, those collectors may have sent their name along with the plants.

 As I was rummaging through my old records for an older catalog, my wife, Joan, thought I was finally about to put all that "junk" out for recycling.  I was not, and I could not find an older catalog for AA.  That leaves us with the 1995 AA catalog as the oldest "documented" use of the term which, I agree, most likely merely refers to the off-white color.

Roland, did you suggest that my plant is T erectum BEIGE?
I got it from a nursery man who is an peony expert  http://www.pionhagen.no/  and he just had a number on it (his own, no collection number).

[bulborum]

No I didn't
I couldn't find an answer where the name T erectum BEIGE came from

Don't know if you got any reply.... as far as I can see, T. grandiflorum is pretty easy-going. It does like (need) sun in the spring but I have it growing in masses in woodsy soil, in clay, in marshy soil, even among rocks with little or no soil. It needs good drainage later in the season as it spends a long time dormant. T. erectum is a little fussier; it likes more shade and more moisture but still good drainage in the later summer and the winter.

Your slightly raised woodsy beds sound perfect!

Thanks, Lis! There seem to be quite a few seedlings in each pot (I sowed them in wide not too deep hanging baskets-8inches? expecting them to be some time to planting out0, so I can try a couple of spots; all still just at single small leaf stage, though I think the seeds were sown fall 2009 from Gardens North moist packs; Some Hepatica sown at the same time are just starting to look like real plants with several leaves and Corydalis nobilis, also same time, are 6 inches high or more,  huge by comparison!

A couple pics of the first Trillium in bloom here   

T.angustipetalum.

A number of pots of different Trillium rivale forms are in bud needing a few days of warmth.

Cheers Dave.

[RickR]

Excellent, Dave!  Not very angusti-folium (narrow-leaf), is it.
  Maybe we should rename it angusti-florum...    Either way, might cool! 

I would have expected T. rivale to be closely related to T. nivale, and thus blooming very, very early.  I guess you just never know with mother nature.

[Hoy]

I am needing a few days of warmth too!

Rick, they're already named angusti-petalum!

Nice Dave! It is still 1/2 year till I can enjoy mine . . .

[RickR]

Rick, they're already named angusti-petalum!

Well, to make what would be a long story short: I should have just re-read that post. Our "embarrassed" emoticon should have a red face...

Rick, you are forgiven    I don't know your long story but I have a tendency to read what I think it is and not actually what it is 

It seems to be a species named T. angustifolium - without narrow leaves too

[bulborum]

You mean Trifolium angustifolium 

Roland

[RickR]

That, in fact, is part of the long story.  It seems there is (was) a Trillium angustifolium that is considered a synonym of a different trillium variety (T. pusillium http://www.theplantlist.org/tpl/record/kew-290554 ).  And even at a glance, when I quickly googled T. angustifolium, up pops a pic that looks just like Dave's plant (and wrongly named, of course).

And blah, blah...
Glad we got that straightened out!
