I received seeds from this plant and WS them. I don't know if they needed the cold strat. but they got it and grew very nicely. They flowered the first year.(2013)
This year they came back and behaved themselves, so I am impressed so far.

That's wonderful to hear. I will try it out and see what comes.

My wintersown plants have been blooming for months. They are small but very nice and behaved so far.

Miss Manners has never performed well for me. I've moved it twice but it still stays stumpy with sparse bloom. I don't understand why since I grow the both straight species and the variegated form with no problem. I think I will move it one more time and if there is no improvement then it will be shovel pruned straight to the compost pile!

felisa, how long have you had your miss manners? My first year with them (last year) they grew from seed and flowered....not a huge display, but flowered nicely for a first year. I transplanted them to their permanent spots late summer and this year they came up and looked so healthy and the flower display was even more lovely than last.
Do you think that maybe they need to establish in one spot for a year or so to be their best? I hope you get to see them at their best. I am very happy with them.

3 years. Long enough to be established.
