I should add that I am not crazy about orange or red flowers so would prefer to avoid witch hazels with those colors.

Arnold's Promise has good fall color, so that might be your best bet. I prefer the Diane for its fall colors, but it has the red flowers.

There are a great many wonderful witchhazels. I have Jelena, with orange flowers, but the orange is so subtle that it's not like being confronted by a huge patche of heleniums. There are also a number of other yellow flowering ones. Fairweather Gardens has a good selection; one called 'Moonlight' might suit you.

Fairweather has more than are shown in its paper catalog, so if you find something and you don't see it ther, check their website or call them. I'm planning to get 'Pallida' this year, but it is thought to be a hybrid of h. mollis and I don't know if that one would be OK in your zone.

It's actually 'Arnold Promise', mckenna, after the Arnold Arboretum. "Arnold's Promise" seems to be a common mistake, made even in nurseries. Appendix 1, Gardener's Selection on page 199 of WITCH HAZELS* lists the following yellow varieties** (Cultivar, Growth habit, Flower color, Fragrance, Autumn foliage):

H. x intermedia 'Angelly', upright, citron yellow, strong sweet, yellow

H. x intermedia 'Arnold Promise' vase, lemon yellow, strong sweet, yellow orange and red

H. x intermedia 'Barmstedt Gold' upright, golden yellow, medium sweet, yellow

H. x intermedia 'Pallida', spreading, sulphur yellow, strong sweet, yellow

H. x intermedia 'Ripe Corn', rounded, yellow, faint, deep yellow

H. x intermedia 'Sunburst', vase, sulphur yellow, no scent, some yellow

H. mollis 'Imperialis', upright, pale yellow, strong sweet, yellow

H. mollis 'Jermyns Gold', upright, golden yellow, strong sweet, yellow

H. mollis 'Wisley Supreme', upright, light yellow, strong sweet, yellow
