Chives

Chives (Allium schoenoprasum) are a perennial bulb-forming herb in the family Amaryllidaceae, widely distributed across temperate regions of Europe, Asia, and North America. They represent the smallest species in the genus Allium, which also includes onions, garlic, and leeks, and are the only Allium species native to both the Old and New Worlds. Chives produce slender, hollow, cylindrical leaves and round, pale purple to lilac flower heads atop leafless stalks, both of which are edible and valued for their mild onion flavour. In the wild, chives grow in a range of habitats including rocky slopes, mountain meadows, riverbanks, and forest edges, typically preferring cool, moist conditions with well-drained soils. They spread both by seed and by vegetative division of their bulb clumps, forming dense patches. As one of the classic fines herbes of French cuisine, chives have been cultivated for culinary use for over 5,000 years and are now grown worldwide in gardens and as a commercial crop. The flowers are also attractive to bees and other pollinators. The IUCN classifies Allium schoenoprasum as Least Concern, with widespread natural populations throughout its native range. While not threatened globally, localised populations may be affected by habitat loss or overgrazing in alpine or subalpine settings.

Comandra Blister Rust

<em>Cronartium comandrae</em>, known as comandra blister rust, is a parasitic fungal pathogen in the family Cronartiaceae that alternates between two unrelated host plants to complete its life cycle. The fungus infects coniferous trees, particularly pine species, during one phase of its development, causing characteristic blister-like galls on branches and stems that can girdle and kill infected tissues. The alternate host is typically comandra (<em>Comandra umbellata</em>), a parasitic flowering plant. On pine hosts, the rust forms orange or yellow spore masses during the aecial stage, releasing spores that infect comandra plants, where urediniospores and teliospores are subsequently produced. The species is distributed wherever its dual hosts co-occur across North America and parts of Eurasia. It can cause economically significant damage to pine plantations and natural forest stands. No quantitative biological metrics are recorded for this species.
