Shepherd's Purse

Shepherd’s purse is a widespread wild weed and a familiar food item in the natural environment of many herbivorous reptiles. It is best used as part of a varied diet rather than as a single major staple.

🌿 Description and Distribution

Capsella bursa-pastoris is an annual or short-lived biennial plant in the Brassicaceae family.

Identified by:

• Basal rosette of toothed leaves
• Slender upright stems with small white flowers
• Distinctive heart-shaped seed pods

It grows in gardens, disturbed ground, field margins, paths, and waste places, often from autumn to spring and again in cooler parts of the year.

🍽 Edible Parts

• Young leaves — the main edible part; best before the plant becomes fibrous
• Tender stems — suitable in small amounts
• Flowers — safe
• Young seed pods — can be offered occasionally

Older plants become tougher and less useful as food.

📊 Nutritional Value

• Calcium: moderate
• Phosphorus: low to moderate
• Ca:P ratio: generally acceptable
• Fiber: moderate
• Vitamin K: useful
• Glucosinolates: naturally present, as in other mustard-family plants

It is suitable in rotation with other weeds but should not dominate the diet.

🐢 Suitable For

• Tortoises (Testudo spp., Centrochelys sulcata, and others)
• Iguanas (Iguana iguana)
• Uromastyx (Uromastyx spp.)
• Bearded dragons (Pogona vitticeps) — as a supplement

🌱 How to Source It

Foraging from the wild

• Gather only from untreated ground
• Prefer young plants from clean meadows or garden areas
• Avoid roadsides, sprayed crop edges, and contaminated urban soil

Growing your own

It can be grown from seed in pots or garden beds, though many keepers simply allow it to volunteer in untreated garden soil.

⚠️ Precautions

• Use as part of a mixed diet
• Prefer younger growth over old fibrous plants
• Do not collect from sprayed areas
• Do not feed wilted or mouldy material

📌 Conclusion

Shepherd’s purse is a useful wild food plant for herbivorous reptiles when correctly identified and gathered from clean areas. It fits best into a varied weed-based diet alongside dandelion, plantain, mallow, and grasses.
