Unit price perSilybum marianum
Milk Thistle, also known as St. Mary's Thistle, is a striking biennial herb with bold, glossy green leaves marbled with distinctive white markings and large vibrant purple flower heads. Growing up to 2 m tall, it creates a dramatic feature in herb gardens, cottage gardens and wildlife plantings. The nectar-rich flowers attract bees, butterflies and other beneficial insects throughout the warmer months.
For centuries, Milk Thistle has been cultivated as both a medicinal and edible plant. The seeds are traditionally used in herbal preparations, particularly in relation to liver health. Young leaves, once carefully prepared to remove the spines, and flower stems have also been eaten as a vegetable, while the immature flower buds may be prepared similarly to globe artichokes. The plant produces a characteristic milky white sap when cut, giving rise to its common name.
Approximately 38 seeds per gram
Approximately 20 seeds per packet

Planting / Sowing
Sow seed 5–10 mm deep directly where plants are to grow or into seed trays for later transplanting. Keep the soil evenly moist until germination.

Wear gloves when handling mature plants due to their spiny leaves and stems.
