Thalictrum 2012

Submitted by RickR on

Sometimes I have the worst luck of the draw. Since childhood, I have been enamored by the dangling stamens of our native tall meadow rue (Thalictrum dasycarpum). But every time I get a plant, and even the few I have grown from seed, have always been females. :( Now, FINALLY I have one! An orphan from our local Chapter sale, I don't even know what it is since it was labeled T. actaeifolium (which it is not), but I love it!

Great portrait photos Rick, always difficult to capture such thin and wispy subjects, but well worth the effort and well done.  And I can relate, the dropping flowers are fetching indeed. I'm a great fan of thalictrum; glad you have finally acquired one searched for a long time.  How tall does this one grow?

It's still in the pot from last year (and about 10 inches).  Now I will plant it in the garden.  The natives where I grew up would grow 5 feet in dry soil under Red pines and on a slope.  They actually seemed to do better there than in moister nearby woods!

What a charming looking plant - so different to a species I have flowering on a raised bed at the moment, Thalictrum orientale. This comes from the eastern Mediterranean and does well in our dry garden. A beautifully delicate little plant.

A little impression of my Thalictrum

Thalictrum 'Anne'

Thalictrum 'Elin'

Thalictrum urbanii (just new in the garden)

Thalictrum ichyanense ichangense maybe T.koreanum (i like these leaves in early spring)

Thalcitrum nishiki

The Thalictrum orientale looks so awesome !!!

A lot of beautiful Thalictrums ;)

Never heard of T nishiki, it looks splendid! So does the T orientale. Tim, does orientale need a Mediterranean climate?
Rick, your unknown meadow rue looks great!

Nice collection, Ernie.

Some species I've never heard of either, but that's not so unusual for me. ;D
They look nice already, but will be even better in years to come!

Aaron, yes, T. dioicum fits well.  If it is a native here, it would be the only possibility, I think.

The ichangense (not ichyaense) does not look right. Ichangense should have peltate leaves and is a small spring flowerer through early summer. Another species frequently goes around under this name as well; T. coreanum, but it is rhizomatous tuberous vs. just tuberous.


Boy, does that make differentiation of ichangense and coreanum easy.  Previously, the best I could find was this attached paper.  Then, mine must be T. coreanum as it is a 30 inch(76cm) mat in six years.  It is the one I posted on the SRGC forum here:

Wow, that was a quick reply, Aaron.  I had problems uploading the PDF, and had to do it by modifying my message after posting.  Since you were so quick, I doubt you saw it on there.  

The plant came from a fellow NARGS chapter member, whom I think bought it directly from a nursery at least fifteen years ago.  I'll ask her and see if she knows the origin.  She may have got it from a place like Heronswood.  I would be happy to send you some.  Unless it's best sent now (and regardless of origin), I'll try to find out her source.
