Habit Foliage Flower Seed pods
Mouse-ear cress (Arabidopsis thaliana) flowers have 4 petals,
are perfect (the have male and female parts), and are very small (2 to 4
mm in diameter).
Typical of many plants in the mustard family, flowers occur on long stalks,
with seed pods forming just below blooming flowers.
The inflorescence of arabidopsis is a raceme, similar to other species
in this family (shepherd's purse, wild mustard, bittercress, etc.).
