Arboretum: An Early Spring Day

I went for a walk as soon as the clouds cleared this afternoon. Judging from the forecast, spring has finally arrived and the plants at the Arboretum are starting to show it. The flower buds of red maples are ready to burst. Snowdrops are the only form of snow left in the area. And crocuses have joined the snowdrops in flower, two weeks later than last year.

Arboretum: More Signs of Spring

The snowdrops are out! We found them near the Explorers’ Garden on Bussey Hill, along the road near the sassafras, and in the marsh, poking out amongst grass and leaf litter.

This gorgeous variety of witch hazel (Hamamelis x intermedia ‘Hiltingbury’) also impressed us.

Arboretum Tree Mob: Witch-Hazels

Next to the Hunnewell building, a shrub has been blooming bright yellow for quite a while now. Refusing to wait for spring, certain species of witch-hazel unfurl their petals as early as January. ‘Arnold Promise’ has a little more patience, waiting until the middle of February.

This past Wednesday, the Arnold Arboretum’s Nancy Rose shared the story of the plant’s origin. In 1928, William Judd collected seeds from a Chinese witch-hazel (Hamamelis mollis) growing in the Arboretum. Seven plants survived the germination process but none were like its parent. Judd deduced that the plants were a cross with the Japanese witch-hazel (Hamamelis japonica) planted nearby. The best of these plants, one that did not hold onto its dead leaves and whose flowers had long, bright yellow petals, was named ‘Arnold Promise.’
