Hamamelis intermedia 'Arnold'

The Story

Plant Bio

Hamamelis x intermedia is a hybrid group of deciduous shrubs or small trees known for their fragrant, spidery flowers that bloom in late winter. They also feature excellent yellow, orange, or red fall color.

'Arnold Promise' is a classic, award-winning cultivar celebrated for its profuse, fragrant, bright yellow flowers that appear later than many other varieties, often in February or March. It has a strong, vase-shaped habit and reliable yellow-orange fall color.

Uses & Benefits:

'Arnold Promise' is a premier shrub for winter interest, bursting into bloom when the landscape is otherwise dormant. Its fragrant yellow flowers provide a cheerful display against snow or gray skies, followed by attractive green summer foliage and brilliant fall color.

Branches can be cut in late winter and forced into bloom indoors, bringing color and fragrance into the home. Its large size and dense summer foliage can provide seasonal screening.

The late-winter flowers are a vital early nectar source for any brave pollinators, like certain moths and flies, that are active on mild winter days. It is generally not bothered by deer or rabbits.

How to Grow

Select a site with full sun to part shade and acidic, well-drained soil.
Dig a hole two to three times wider than the root ball.
Amend heavy clay or poor soil with compost or pine bark fines.
Set the plant so the top of the root ball is level with the soil surface.
Backfill the hole, gently firming the soil around the roots.
Water deeply after planting and mulch to conserve moisture.

Pro Tip

Plant where you can enjoy its winter fragrance, such as near an entrance or window, and give it ample space to achieve its natural vase shape.
