I just got back from a week in the Netherlands looking at new plants. Here are a few that I found interesting. Which do you like?
This is a greenhouse bench filled with Lo & Behold 'Blue Chip' Buddleia. It will be introduced in Europe next spring. I've never seen so many butterflies in one place in all my life. The Boskoop Royal Horticlture Society has it awared it a gold medal. 
Chasmanthium 'River Mist' is acutally an American plant but it won a Gold Medal from the Boskoop Royal Horticulture Society. It was developed by Itsaul plants.
Echinacea 'Irresistible' is just one of may new Coneflowers on the market. Below is a vase shot of one assortment now on the market.
This is a new larged variety of Hibiscus moscheutos called GH7 or Guido Oak Red. 
This is one the the best red leafed grasses I've ever seen. It's not hardy but can be used as an annual in the North. It's called Pennisetum setaceum 'Fireworks' and I love the contrast with the green interior leaves. 
Pretty Much Picasso petunia is available here in the US but it has made a big splash in Europe as well. It won a metal from the Boskoop Roayl Horiculture Society for one of the best new plants for 2009.
