A Look Inside the Morris Arboretum Herbarium

·

An herbarium is a lot like a library, except instead of books it holds botanical specimens. The Morris Arboretum Herbarium contains more than 25,000 specimens, all of which have been digitized. From pressed orchids to parasitic mistletoe to oak branches with acorns, the Herbarium hosts a diverse array of plants.

Snowflakes vs. Snowdrops: Pendulous Beauties of Early Spring

·

Two similar plant species caught my attention at the Morris this week because of their attractive and early season blooms: Galanthus nivalis (snowdrop) and Leucojum vernum (spring snowflake). ). Often called “harbingers of spring,” both are bulb plants and have nodding flowers, sometimes spotted peeking through snow (hence the common names).

Plant Names and Provenance: Edgeworthia chrysantha (paperbush)

·

Edgeworthia chrysantha is a shrub that bears fragrant flowers in the winter. While most genus names honor one person who is often a man, Edgeworthia commemorates a brother and his half-sister, each notable in their own right.

Thinking Ahead of Climate Change

While the warmer winters in Philadelphia may not be normal in 2023, it could be normalized sooner than we think, and the Arboretum has been actively thinking ahead of climate change for over a decade.

What's in Bloom: November

·

As we all prepare for colder months, many of our plants are doing the same: dropping their leaves, slowing glucose production, and storing excess food in their root systems. Some plants in our gardens are still displaying vibrant fall color, and others have even begun to bloom. I hope you enjoy stumbling upon these plants at the Arboretum and discovering new ones along the way.
