Information on Thalictrum

11 years ago

I recently acquired two Thalictrum plants that had seeded themselves beneath my friend's mature plant. I don't know what variety it is. It is very large.

I realize there are male and female plants. I'm assuming her plant is male because she says it's very showy. If her plant is male will my plants be male or could they be either male or female? Do I have to wait until they bloom before I know?

I would appreciate any advice you could give me.

Sorry can't help, but a learning moment for gardeners like me.

Rediscovered a great on-line Thalictrum article - "Thalictrum -Meadow Rue", Rob's Plants.

Rob says that of the 200 or so Thalictrum species, some are dioecious (flowers of one sex) and some are hermaphroditic. "The latter tend to have the showier flowers", which could suggest some of these could have become garden varieties.

Therefore which garden Thalictrum are dioecious?

We have a number of Thalictrum cultivars, most of which we've had for for 5 to 10 years. Have read that my favourite the hybrid 'Splendide' (thank's Rouge!) is sterile.

Thank you so much for the input. I can't say it answers the question,but with that many species, the question is probably unanswerable.

Thank you also for turning me on to Rob's Garden. Fabulous!

Rosemary, that guy loves Thalictrum like I love garden phlox.

There's no accounting for tastes!

And thanks for forcing me to learn. Think that's one of the attractive things about gardening; namely, opportunity to learn. I just wish it was simultaneously easy on the joints.

I agree! I agree about learning and I agree about sore joints!

One would speculate that ((unless she has a second plant somewhere)) it is a hermaphrodite form of Rue. it is doubtful just having a male plant would produce seedlings ;-)

If you were to post a picture here when it blooms we may be able to help identify the variety.

Love dem' rues! ;-)
