We had a white NOID that seemed to have good stem strength. Large flower, heavy bloomer. Everything in the center of the clump stood fine but the ones on the outside edges drooped into the lawn. If they weren't cut for a vase I'd cut little forked sticks (think fishing) and wedge them into the clump to keep everything nice and tidy throughout the bloom.
I don't grow anything pink specifically but I bet my Mom would enjoy "Magical Encounter". She has a peachy pink NOID that she likes but after viewing the photos here it's not nearly as attractive.
