Plant Profile
parsleyPetroselinum crispum
Parsley is the crown jewel of the Central European herb garden. Whether curly or flat-leaf, it enriches almost any savory dish with its fresh aroma. As a biennial plant, it requires patience during germination and discipline with crop rotation, but rewards the gardener with a harvest extending deep into winter.

Overview
Cross-pollination primarily by insects such as flies and wild bees.
Notes
Flowers are protandrous (pollen shed before stigma is receptive), which hinders self-pollination within the same flower.

Edibility & safety
parsley Edibility & safety
For people
In brief: which parts are edible, which parts remain risky, and whether raw consumption makes sense.
Safety notes
Contains apiol; levels rise significantly during the flowering year, which can be toxic (especially to be avoided by pregnant women).
Animal safety
For animals, the specific plant part matters here: some parts may be suitable, while others should be avoided. At least one critical rating is listed for 4 animal types.
Each row shows which parts are more suitable and which parts are critical.

Parsley is safe for rabbits in moderation, particularly the leaves and stems. Large quantities or plants in the flowering stage, which have higher apiol and furanocoumarin levels, can cause photosensitization. Consumption should be limited to small amounts as a treat.

observe
Parsley is safe in moderation for guinea pigs, particularly the leaves and stems. Large quantities or plants in the flowering stage should be avoided due to apiol and furanocoumarins, which can cause photosensitization in sensitive animals or with excessive consumption. Vitamin C content is beneficial.

observe
Parsley is generally safe for chickens when fed in moderation. Large quantities or flowering plants may contain apiol, which can be harmful in very high doses. Leaves and stems are the safest parts. Seeds should be avoided.

Parsley is generally safe for sheep when fed in moderation. Large quantities, especially from flowering plants, can lead to photosensitization due to apiol and furanocoumarin content. Leaves, stems, and roots are the commonly consumed parts and are considered safe. Feeding should be limited to non-flowering parts.

Photosensitization (sunburn, dermatitis) if large amounts of plants in the flowering stage are consumed
observe
Parsley is generally safe for pigs, especially the leaves, stems, and roots. Consumption of large quantities, particularly of plants in the flowering stage, can lead to photosensitization due to apiol content. Feeding should therefore be moderate, and plants in the flowering stage should be avoided.

Common beginner mistakes
Cutting too deep during harvest destroys the heart leaf and stops regrowth.
Success pattern
Consistent moisture during the first 4 weeks ensures a dense crop.
High-impact tips
Marker sowing with radishes helps identify the rows of slow-germinating parsley.
Grower observations
Flat-leaf parsley is significantly more robust during heatwaves than curly varieties.

Why is my parsley turning yellow?
Common causes include waterlogging, nutrient deficiency, or pests like the carrot rust fly.
Is parsley safe for Dog?
parsley is classified as toxic for Dog. Risk: 4 / 5. Urgency: contact a vet if ingested. Large quantities are needed to cause this effect. Apiol content increases during the flowering stage.
Is parsley safe for Cat?
parsley is classified as toxic for Cat. Risk: 4 / 5. Urgency: contact a vet if symptoms appear. Parsley is toxic to cats, especially during the flowering stage when apiol content is highest. Large quantities can cause photosensitization.
Is parsley safe for Rabbit?
parsley is classified as moderation only for Rabbit. Risk: 2 / 5. Urgency: observe. Parsley is safe for rabbits in moderation, particularly the leaves and stems. Large quantities or plants in the flowering stage, which have higher apiol and furanocoumarin levels, can cause photosensitization. Consumption should be limited to small amounts as a treat.
