One hundred Ramsons (Allium ursinum) courtesy of Shipton Bulbs. Wild Garlic is another name for this species; the cigar-shaped bulbs and tendril-like roots are pungent. Ramsons can be prolific (and reeking) in wet woods in late spring, for example see my entry dated 29th. April 2019 concerning Gopher Wood in Wiltshire.
As good a garden plant as many other bulbs A. ursinum is becoming more widely available for autumn planting. In the past only specialist nurseries like Shipton cultivated it but the interest in wild food and wild gardening has no doubt enhanced its appeal. Easy to grow in a shady spot as long as the soil is very moist.
