Name derivation:
Veronica possibly named after Saint Veronica, a nun who died in Milan in 1497. Alternatively from the Latin 'vera' and 'icon' meaning true image. This is in reference to the legend of the miraculous imprint of the face of Christ on a headcloth that Saint Veronica offered Christ on his way to crucifixion. Peregrina from the Latin 'peragrare' meaning to move or travel or to proceed; referring to the ability of this plant to easily expand itself in its habitat. Xalapensis mean of or from Xalapa, Vera Cruz in Mexico; referring to where the subspecies was first collected from.

Annual herb to 30 cm high with dense glandular hairs, the hairs spreading, straight and of even length. Erect stem simple or with ascending branches forming at the lower nodes, flowering at all but the lowest nodes. Leaves connected across the node by a ridge, spathulate to narrow-oblong, to 12 mm long and 3 mm wide, entire or sparingly serrulate. Flower-spike terminal, with 10-30 white flowers. Flowering between September and November.
Fruit type:
Flat heart-shaped capsules turning from green to brown as it matures. Each capsule contains a few seeds.

Seed collecting:

Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
