Night Dreams--red purple, much more purple than shown here. Second year here and doing really well. It produced a proliferation which we have rooted, so will have another plant. Bloom size is 3.5".
Orchid Flounce--this may not meet your color qualifications but it is a lovely 3.5" flower and excellent grower. It is on its second set of rebloom scapes.
Little Trooper--3" flower, second year, has not been a strong grower for us, hoping for better in time.
I also grow Star Child and Dragon Dreams. Have you seen or heard of Purple D'Oro? I think that is one I should get. Check it out on the NGA Plant Database. Another one might be Pugsley, it is a mini, just under 3".
