Perennials: Plant of the Year in your garden?, 1 by Pistil

Geranium 'Biokovo'- flowers were muddy looking and did not really bloom all summer, for me there are much better Geraniums, but it was very hardy.
Brunnera 'Jack Frost'- slug bait, but 'Sea Heart' seems resistant.
Baptisia australis-lovely for a week each year, then at age 4 it just died.
Hakonechloa macra 'Aureola' needs too much water
Geranium 'Rozanne'- a winner
Dianthus 'Firewitch' was great in a planter, did not survive in ground
Hellebore x hybridus- very nice, but pick your plant in bloom lots are muddy.
Leucanthemum 'Becky' weird combo of not hardy but thousands of offspring
Calamagrostis 'Karl Forster' the stalks are not strong and they fall sideways yuck.
Scabiosa 'Butterfly Blue' not hardy, but 'Perfecta Blue' is.
Rudbeckia 'Goldsturm' stiff, but hardy and floriferous
Echinacea 'magnus' dull muddy flowers not very noticable, not very hardy.
Salvia 'May Night' nice on sand, not hardy on clay
Perovskia atriplicifolia flops, but 'Blue Spires' from High Country Gardens' much better
Veronica 'Sunny Border Blue' nice for a few weeks, then looks bad all summer
Coreopsis 'Moonbeam' does bloom all summer, but every dead flower remains and is hideous. must be cut off individually and then the plant looks like a bad haircut..
Phlox stolonifera not hardy in my acidic clayey soil wet winter dry summer.
Nepeta 'Walkers Low' not hardy in my clay.

It seems these are mostly for more 'normal' American climates. Locally the "Great Plant Picks" is attempting to make a list more suitable for our particular climate. Good plan!
