Positive coriaceous On Feb 11, 2014, coriaceous from ROSLINDALE, MA wrote:

A consistently good bloomer, and the latest of the witch hazels to bloom. It starts to bloom in late winter, though when exactly varies considerably from year to year, and it stays in bloom for a little over a month.

Large fragrant flowers, a clear bright lemon yellow. Blooms best in full sun, but partial shade is good, too. Fall color is best in full sun.

This is a small tree rather than a shrub, usually reaching 15-20'. It has a beautiful natural vase shape and herringbone branching pattern that are easily destroyed by pruning. Heavily pruned plants do not flower well. It's best placed where its natural form and size will be assets.

Though cuttings root easily, this tree is usually only available grafted onto H. virginiana roots. Own-root plants are much more desirable, as grafted plants sucker a great deal and suckers need to be pruned off frequently if the rootstock isn't to outgrow the cultivar. (You can recognize the H. virginiana suckers because they retain their browned leaves into the winter.)

Seemed slow to establish; profuse suckering but no disease issues. Takes drought once established. Nice fall color but spring blooms adversely affected by late season drought. Seems to be partial to acidic soil.

My Arnold's Promise has been living in a pot for 4-5 years here in Seattle. Last week (early Feb) two blooms appeared, and that's all. What's the problem? Can I expect more, or is that it for this year?

Thanks for any guidance.

P.S. I bought the plant at Swanson's Nursery in the hope of winter fragrance, but it has never been fragrant at all.

Beautiful intense yellow flowers and gourgeous fall foilage

Does better than Hamamelis vernalis here. Even after a mild winter, H. vernalis doesn't flower well but this one is pretty reliable.

Arnold Promise was the first variety of Witch Hazel that I added to my garden, and it had me hooked on it's beautiful form and early splash of color from the first year. I would question the 4'-6' height listing though, as I have had to prune twice a year to keep mine at 6'. I really wish I had planted it somewhere else where I could let it grow to it's heart's content. I would not describe It's fragrance as "sweet", but is nice and I can smell it from 20' away when it is at is prime. This is one plant that I will definitely never be without.

Positive ViburnumValley On Mar 9, 2008, ViburnumValley from Scott County, KY (Zone 5b) wrote:

'Arnold Promise' witch hazel is the first of this fine species that I had the pleasure to become acquainted with (and plant for myself) back in the 1980s.

I have enjoyed this large-growing shrub to small tree sized plant and its copious late winter and early spring fragrant bright yellow blooms. The only downside to 'Arnold Promise' performance is that it often overlaps in bloom time with the ubiquitous forsythia around central KY. Given the choice, most gardeners know what a forsythia is, and nurseries will sell them a thousand to each one witch hazel.

This is a fine plant, but it is rapidly being superceded by newer selections that bloom earlier in the winter when there is little to no competition.

I look forward to the late winter flowers every year! Blooms around Mid February around here-sometimes a bit earlier, and lasts about 4 weeks.

This is probably the most well known witch hazel and rightly so; the flowers are among the largest of the witch hazels and are a brilliant yellow. It was a selection made at the Arnold Arboretum, Mass., in 1963. This cultivar also has excellent fall colour.
