Deadnettles do not have a good reputation as they tend to spread unchecked in the garden. Still, it's worth caring for a few deadnettles, because not only is the plant non-poisonous, it's actually edible.

Deadnettles are not poisonous
Deadnettles are not poisonous in any part of the plant. On the contrary: the leaves and flowers give wild salads and other dishes a spicy or sweet note.
You can safely plant deadnettles in the garden, even if children and animals use the garden.
Many herbivorous pets are very fond of the sweet flowers. Deadnettle blossoms are therefore well suited to enriching the diet of rabbits, turtles or guinea pigs with fresh herbs.
tips and tricks
To combat uncontrolled spread of dead nettle in the garden, you need to uproot the plants. No root residues should remain in the ground. It is best to get rid of the plants before flowering.
