Disclaimer: Foraging can be fun, rewarding and provide health benefits. As a novice forager, I will be sharing my foraging experiences. However, in order to be safe, always consult with local foraging experts and guidebooks before beginning foraging. Children should learn to forage safely by being guided by experienced adults. Never ingest anything unless you are certain of the identification and safety of the plant. Some plant species are inedible and some are poisonous.

Date Location Notes Images
July 19, 2012 Southeastern, New Hampshire This plant was at the edge of a dry field. But the field gets flooded during ocassional rain storms. I went through the Mustard family key several times to first confirm that this was a Rorippa and then confirm the species. Key:
  • Fruit is a silicle (up to 3 times as long as wide). Note: some of the seed pods were slightly more than 3 times as long as wide and some were less.
  • Silicle dehiscent (splits open at maturity), containing 2 to many seeds.
  • Silicle not compressed at right angles to the septum (seed partition).
  • Silicle compressed, narrower than 6 mm. Flower petals white or yellow.
  • Flower petals not deeply-notched. Fruiting pedicels spreading to ascending.
  • Silicle symmetrical and without tubercles (swellings of different colors and/or textures).
  • Silicle not compressed.
  • Plants glabrous or pubescent with unbranched hairs.
  • Principal leaf blades pinnately-lobed. Petals yellow (except in one Rorippa species). Genus identified: Rorippa.
  • Flower petals yellow or absent. Leaf blades subentire to pinnately lobed.
  • Flower petals present. Fruiting pedicels 2-15 mm long.
  • Flower petals 0.7-3.5 mm long, shorter than or equal to the length of the sepals.
  • Silicles ovoid-obloid to broad-ovoid, 3-10 mm long. Flower petals 0.8-3.5 mm long. Species identified: Rorippa palustris.
  • Stem glabrous. Back of leaf glabrous or sparsely hirsute (coarse, somewhat stiff and curving hairs) near the base. Variation identified: Rorippa palustris var. palustris.
