Allium senescens, commonly known as German garlic or broadleaf chives, is a bulbous herbaceous perennial. It is native to a variety of habitats including grasslands, rocky outcrops, and the edges of forests in Asia, from Siberia to Korea. This species typically grows 8-40 inches tall and produces showy umbels of up to 30 pink flowers from mid to late summer, which are attractive to pollinators. The foliage is thin and straplike, with a bluish-green hue that adds texture to garden settings. While it has been introduced and naturalized in parts of Europe, such as the Czech Republic and former Yugoslavia, it is not considered invasive.

German garlic is valued for its ornamental flowers and is often used in rock gardens, borders, and as an edging plant. It is also planted for its culinary uses, similar to chives, and for its potential in breeding programs due to its genetic relationship to A. cepa, the common onion. It thrives in full sun to part shade and prefers well-drained soil. While it is drought-tolerant once established, consistent moisture will promote vigorous growth. It has received the Royal Horticultural Society’s Award of Garden Merit in the UK, indicating its exceptional performance in gardens. Potential problems include onion fly and thrips, but these are generally not severe.CC BY-SA 4.0
