Using plant chemistry and insect preference to study the potential of
Barbarea (Brassicaceae) as a dead-end trap crop for diamondback moth (Lepidoptera: Plutellidae).

Phylloplane location of glucosinolates in
Barbarea spp.
For instance, severe aboveground biomass removal of velvet leaf (Abutilon theophrasti) and ruderal herb (
Barbarea vulgaris) resulted in fruit number decline with increasing severity of harvest [11, 12].

Creasy greens (
Barbarea vugaris and B.verna), or winter cress, with their mustard flavor and edible leaves and flowers, are another one of my spring favorites.
Don't forget the weeds that make nutritious people food as well: dandelion, upland or field cress (
Barbarea verna), burdock, and poke, whose (very short, early) shoots make an excellent cooked spring tonic.
