Maianthemum stellatum Observations
(star-flowered Solomon's seal)

Submit Data Observations
Introduction to the NPN Native Species Observation Program

Star-flowered Solomon’s Seal (also known as Solomon plume or wild spikenard) is an elegant wildflower (15–60 cm) with tall, arching stems, that prefers woodlands, open meadows and shores of sandy marshes. The narrow, grey-green leaves have long, noticeable veins. Leaf size and shape can vary, depending on where the plant is located. In bright light, the leaves are stiff; in shade, they are limp but tend to grow larger. The white flowers (up to 6 mm wide) have six petals, and form a loose group at the end of each leafy stem. Berries are greenish with dark stripes, before turning red, and then nearly black, in early fall.

You should record when two well-defined phenological events occur for star-flowered Solomon's seal:

  1. First bloom (FB) First select an approximately 1 by 1 meter plot for observation, and then record the date when first flowers are open in at least three places on the observed plants.

  2. Mid bloom (MB) Within the same 1 by 1 meter plot used for first bloom, this is the date when 50% of the flowers are open on the observed plants.
