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).

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). Their mostly white flowers explain their generic names: Galanthus means “milk flower” and Leucojum “white violet,” both from (ancient) Greek. Their physical similarities are no mere coincidence, but instead the products of evolution as the two are related. Leucojum and Galanthus are sister genera in the tribe Galantheae, along with a third genus Acis (Larsen et al., 2010) and they all belong in the plant family Amaryllidaceae, also home to commonly cultivated amaryllis and daffodils. Image Galanthus nivalis flowering at the Morris Arboretum. Image Leucojum vernum flowering at the Morris Arboretum. Let’s consider the form of the three genera in tribe Galantheae. The easiest way to tell Galanthus apart from the other two genera is by the three large outer and three small inner tepals (petal-like structures) seen in its flowers, while Leucojum and Acis both have six equal-sized tepals (also three outer and three inner by position). Both Leucojum and Galanthus have markings on their six tepals, while Acis has none. One last characteristic is that Leucojum typically has a hollow scape, while the scape is solid in Galanthus and Acis . If you’re a …
