Annette, your garden combos are always so gorgeous! I'd love to see your garden in person one spring when the peonies are blooming!
I HOPE my parrot tulips continue to come back every year! I planted the first here around 3 years ago, probably around 50 bulbs, and they've multiplied every year so far. Ordered different colors this fall to add to the existing ones. I know we weren't able to overwinter them in the ground where I lived in Texas, didn't get cold enough for them, but I would've thought they'd be fine in zone 6! We're zone 4b here, colder than the surrounding areas because of our altitude. I grew other varieties fine in Parker as well and it's zone 5 along with the rest of the front range. The parrot tulips were at their peak here the 3rd and 4th week of May--there were so many of them we cut a bunch to use for table centerpieces for my daughter's high school graduation party. The earliest peonies showed up the very end of May, my fernleafs started opening just before I left for the APS convention.
