Overview

Claytonia is primarily pollinated by bees and other insects. The plant is self-fertile, but cross-pollination improves seed set.

Notes

Insects such as honeybees and bumblebees visit the flowers. In closed cultivation (e.g., polytunnel), hand pollination may be necessary.

Edibility & safety

winter purslane Edibility & safety

For people

In brief: which parts are edible, which parts remain risky, and whether raw consumption makes sense.

Edible parts:Leaves, Stems
Caution parts:Flower stems (may be bitter) on older plants, Seeds (not recommended)
Raw consumption:Yes, safe to eat raw. Wash thoroughly before consuming.

Safety notes

Claytonia is non-toxic and safe for human consumption. In large quantities, oxalic acid may cause mild irritation in sensitive individuals.

Animal safety

For many animals, this plant is generally low-risk: 14 animal types are rated suitable or mostly suitable. Quantity, plant part, and individual tolerance still matter.
