I think it's an Achillea ptarmica. I have Achillea ptarmica 'Angel's Breath' with leaves like that. My blooms are fully double, though.

Hey Paula did you start it really early? I had luck with mine when I got it mail order April of 2002 (when I first did this post! Wow I can't believe how long ago that was and this post is still kicking around). I planted it out right away when it was still cool and wet out and by the time the heat came around it was settled in nicely and needed no special care. However we had a really cold winter that year and it did not survive. I am curious as to how yours would do long term though come to think of it I do believe that I remember hearing of one in Virginia. What do I know though? I'm certainly not growing one now. I know they were very easy in coastal California (the garden I was at was digging up seedlings all the time and selling them in the nursery) and in England they were incredible. I will look for my pic from Wisley and post it.

I built a Peter Rabbit Garden in 2001 for my Granddaughter & me. We even had the scarecrow and little blue slippers with the Tamashanter hat. We grew: Marvel Peas French Breakfast Radishes French Beans Bib Lettuces Italian Flat Parsley Carrots Cabbages Some Sweet 100s tomatoes Blackberries (served with cream & scones for supper) Chamomile (for tea) Munstead Lavender (rabbit tobacco) Strawberries Muskmelons (Hale's Best) grown upon the back fence... and a Cucumber frame (grown on a wire arch at the back) With fern-like Dill and Calendula flowers planted round about. I set a 1/2 whiskey barrel in the center for our Mr. McGregor's pond with hardy water lilies and some goldfish. :) I used rocks for bed borders and twigs for wattle edging. It was very quaint and tasty! For Inspiration to create your very own Peter Rabbit Garden (er...Mr.. McGregor's Garden), see the Link below. We even had a picnic one afternoon with cucumber sandwiches and Earl Grey tea (my favorite tea). What fun. She loved it! ~Annie

Steve, Great photos and I'm so glad you had some of the statues (in the woods, right?) It was one area we couldn't make it to. I visited for the first time this year and it has moved very high up on the list for gardens to go back to. I thoroughly enjoyed it. Steve, I hope you don't mind I'm adding my album to this thread too. Our pictures are different and I think between the two of us everyone can get a good feel for the place. I especially love they way they spray painted the dried allium heads as some garden art. Here is a link that might be useful: Tower Hill July 2011
