I think Northwind dancer is meant to "dance" in the wind! I am starting to collect tall, spidery pastels for a special bed and these are some I have and like: Gudrid / Miss Jessie / Parfait / Jurassic Spider / Northwind Dancer / Under the Wire. Woodhenge Gardens is the home of Margo Reed and Jim Murphy, both of whom do wonderful tall many budded UFs and Spiders. Brian Mahieu's cultivars are being sold here and there, and are usually quite tall, well budded and sturdy.
