Yesterday my group headed for the Chelsea Flower Show, but before we went in, the Yinzers posed for a shot with their Terrible Towel!

It's the Steeler's Nation across the pond.

I was spellbound by Anthriscus sylvestris 'Ravenswing.' Check out the picture below, I hope I can find seeds for this plant.

Today we're visiting the gardens of Hampton Court.

The airy white flowers of Anthriscus sylvestris 'Ravenswing' against it's purple stems made my heart flutter.

I'd always dreamed of seeing the Chelsea Flower Show. It's the Super Bowl of garden shows. I had no idea what to expect and was blown away by the scope and size of the centennial show.

There are 15 show gardens which take three hectic weeks to construct. Acres of vendors selling everything you could possibly imagine to make a gardener happy.

There were many amazing sculptures on display at the show.

Tiny artisan gardens dot the edge of the perimeter of the show. There are more gardens around the Great Pavilion and even though my group was there on members day, the crowds were crushing. Often times they would be five deep standing in front of a garden. They are polite though. After a couple minutes a person would leave the front, providing room for another until you would finally be standing in front of a beautifully designed garden.

I fell in love with Anthriscus sylvestris 'Ravenswing' or cowparsley. It's airy white flowers are set off by purple stems. It was used in most of the gardens in the show. I hope I can find seeds.

Even though all the outdoor gardens were spectacular, the exhibits in the Great Pavilion took my breath away.

Imagine any plant you ever thought about growing displayed in its prime. Each vendor has a specialty, whether it's bulbs or lavender with an exhibit massed with their plant of choice.

Gardeners can take a look and buy the seeds, plants, bulbs or tubers on the spot.

It's probably the most incredible thing I've every seen.

I'll be posting more about my experiences there in the next few days. One thing I'll never forget was a display of six foot tall delphiniums towering over the biggest begonia blooms I'd ever witnessed.

This mass of giant delphiniums towering of huge begonia blooms was one of the first things I saw after entering the Great Pavilion.

The East Village Garden was one of the spectacular Show Gardens.

Don't let anyone tell you the English don't have a sense of humor.

Last week the Post-Gazette had a story on wisterias and I had a photo of a 65 foot tall plant from Ohio Township.

As impressive as that was, wisteria blooming along the streets in busiest parts of London is amazing.

Wisteria is everywhere in London. This plant was growing up a building on a side street downtown near Harrod's.

It's used on the fronts of buildings and most are painted white, setting off the purple blooms beautifully. I walked for miles through London and saw ancient vines twining around trees, gutters and porch columns.

One of the cool things about visiting a country obsessed with gardening like England is seeing new plants. Usually most gardeners can get close identifying a variety, but I found three which stumped me.

The first two were photographed at the Victoria and Albert Museum in the John Madejski Garden.

I was was drawn to the purple blooms of a plant which looks kind of like a mum, but with purple stems and it's four feet tall. The bees loved the flowers. Have you seen it before.

The other is an upright, spike like bloom nearly six feet tall with small, pretty blue flowers. It resembles a verbascum.

The last flower I found on the walk back to the hotel. Maybe a camelia?

Take a look at the photos below and see if they look familiar and let me know what you think they are in the comments section at the bottom of the blog.

I'm finally on London time after a good night's sleep and can't wait to visit the 100^th anniversary of the Chelsea Flower Show tomorrow. The group I've brought have special access on members day. I'll post lots of photos tomorrow.

Do you know what this plant is?

I would love to know what this plant is. It's nearly six feet tall and filled with blossoms.

These beautiful white blooms covered a plant along the sidewalk as I headed back to the hotel in London. I've never seen it before.
