Pulmonaria 'Mrs Kittle': Lungwort (Pulmonaria 'Mrs Kittle')
Pulmonaria rubra 'Mrs. Kittle':

The only semi authoritative source I've found lists both. http://www.bgci.org/plant_sear...

This is a lot more common in the DB than I'd like to admit. I have a script that I ran a couple days ago that looked for duplicates and found several hundred plants that seem to be duplicates - two (or more) plants with the same genus and cultivar. Sometimes the species differs and sometimes the spelling is just slightly off (as in your example plant above).

I'm grappling in my mind what should be the right solution here. Probably I'm going to make a report that is accessible for everyone to see, so we can start looking through the list and just delete the duplicates.

A list would certainly make things easier. In Pulmonaria, with only 2 pages of listings, a Ctrl+F search was quick and painless. I believe it picked up 1 triplicate. Some genus are way too big for that shortcut. I wager we'll be able to whittle it down post haste.

I'll see about getting that list up tomorrow.
