'ispahan', I have none of the ones you have listed but I can give two thumbs up to the most petite thalictrum I possess...."Evening Star". I have several and even though they are all in significant shade they are in flower most of the season; at the same time having wonderful foliage..

I also have "Sparkler" and in this its first full season in my garden it grew to about 4 feet in height with white flowers...nothing outstanding...maybe it will be better in subsequent years.

Second thumbs up for 'Evening Star' - can't rate it highly enough!

Other than that one, 'Hewitt's Double' and an early yellow (T. flavum ssp glaucum?) I have sold but not personally grown several of the newer intros. 'Elin' looks especially interesting......if I had more room :-)

What is frustrating re "Evening Star" is that I find it impossible to capture its loveliness on film.

I have been mulling over planting a border of ES for a small shade garden.

I also have "Sparkler" and in this its first full season in my garden it grew to about 4 feet in height with white flowers...nothing outstanding...maybe it will be better in subsequent years.

UPDATE:

"Sparkler" is so healthy and vigorous. It is over 4 feet tall, (so far self supporting) and quite lush and floriferous. Here it is as of today:
