LOOK ALIKES: Make sure that you are not harvesting young Butterweed, which has yellow flowers. It is very toxic.
EDIBLE YOUNG LEAVES, STEMS: I really enjoy eating this diminutive annual green. Eaten raw or cooked. Older leaves may be better cooked. Peppery, sometimes slightly bitter, delicious. “An excellent Watercress substitute.” [4/105?] “The flavor of this plant is similar to broccoli rabe but a much milder. “  Harvest from winter through April in central Florida. CAUTION: At certain times of the year, tiny butterfly eggs may be common on the leaves. Discard or do not pick these ones.
EDIBLE SEEDPODS: “Seedpods raw or pickled.”  Peppery.
EDIBLE ROOTS: “The grated raw root is used as a condiment.” [4/20?] Green Deane writes, that “some roots can make a good horseradish substitute,” and the “it is not at all unusual for the roots of such plants to be ground up and mixed with vinegar and salt to make a horseradish kind of sauce.” I have eaten the raw roots as a trailside nibble and have always found them to be too fibrous. I will try grinding them in the kitchen, and attempt to make a horseradish-like sauce. I will report back.
MEDICINAL USES: “The leaves and the flowering plant are carminative and digestive.” [4/172?] “It contains glucosinolates which are known to help remove carcinogens from the body. It also contains, vitamin C, beta-carotine.” 
WILDLIFE: Pollinated by bees, flies, and butterflies. 
POULTRY FORAGE: Chickens and ducks enjoy munching on this low-growing, tender plant.
WILDLIFE: It is host to a certain butterfly, which I have yet to identify.
NATIVE TO: North America, “Newfoundland to Minnesota and Montana, south to Florida, Tennessee and Kansas.”  In Florida, most counties across the entire state.
HABITAT: Moist to wet areas “such as mud [along streambanks] or riverbanks.”  Also lakeshores, swamps, wetland margins.  It is “is weedy in nurseries and greenhouses.” 
DESCRIPTION: A somewhat inconspicuous annual or usually biennial small herb. Pfaf.org lists it as a perennial as well, which is questionable.
- STEM: “Producing one or more erect or leaning, branching stems which are purple to green in color and grow 4–28 inches tall.” 
- LEAVES: Leaves compound., alternate, most often deeply lobed, vary greatly, with “three distinct veins.”  “The edge of the leaf blade has both teeth and lobes.” 
- FLOWERS: Flowers tiny [1/16-1/8 inches wide], white, four petaled. I find it here in south-central Florida appearing from winter through April, although Green Deane says “April to October.” Often, two wildcrafters are both correct, via different experiences in varying parts of the state.
- FRUIT: A thin seedpod.
OTHER RELATED SPECIES FOUND WILD ACROSS FLORIDA: There are four other Caradmine species found wild in Florida. 
- C. bubosa– BULBOUS BITTERCRESS - native – many scattered counties, Polk northward.
- C. hirsuta– HAIRY BITTERCRESS – not native – scattered counties, Hernando northward. Prefers wet sites. 
- C. parvoflora– SAND BITTERCRESS – native – Alachua and scattered counties in the panhandle. Prefers dry sites. 
- C. concatenata– CUTLEAF TOOTHCUP [aka Cutleaf Bittercress] – native – 3 panhandle counties. The leaves leaf looks like another wild plant, Tread-softly, without the spines.

Riverbanks, Wet Areas
- HARDINESS: USDA zones 4-8.
- LIGHT: Semi-shade to sun.
- NOTES: Green Deane writes, “Under cultivation C. pensylvanica can be coaxed to grow to more than a yard high and wide. A perennial herb, it can be trained into round shrub. Oddly, when raised intentionally it does not like to be wet and one has to water it moderately.”
