@grannysgarden
I have Hell's Gate and it has increased enough to send you a piece. I am interested in others of Denise's introductions myself.

I just planted a small rhizome of Sirocco Mist this year, a trade with a local grower. It may take a couple of years to increase enough, but I have noted you want it.
I am looking for:
Brighde - Stewart 2012
Carmel Topping - Stewart 2010
Celtic Fairie - Stewart 2012
Feeforin - Stewart 2015
Myra's Child - Greenlee 1971
Poplyte - Stewart 2011
Rosemary's Dream - Dunderman 1982
Tanzanite - Marky Smith 2006 Lost mine
I can find the Stewart varieties and Tanzanite listed by Tara Perennials in Southern Ontario. But I can't find on their website if they mail to the US, but I doubt it.
