I've had RUFFLED STRAWBERRY PARFAIT for 3 years. Started from a single fan and is now 4. I have it growing in a spot that is shaded until about noon during the summer then gets full afternoon sun. Like Cindy said, it's a very late blooming variety; in fact I think it's the last thing to bloom in the garden unless there are rebloom scapes. It's a fully dormant plant that is slow to emerge but grows wonderfully once it does. Blooms seem to open with no problems but the latter ones have a less pronounced edge than the first. I just went and counted (posting from the back porch today because it's GORGEOUS outside!) and I had 3 scapes with bud counts of 16, 14, and 11. It's pod fertile for me but given how late it is I've not tried the pollen. Does seem to have decent rust resistance but I generally try to keep that under control so I haven't truly tested it.
If memory serves its the parent of some of Polston's toothy beauties so that edge does get passed on.
