Safety Overview
1.Costmary — Plant Snapshot
Costmary, or Tanacetum balsamita, is a resilient perennial herbaceous plant within the diverse Asteraceae family, typically reaching heights of 60 to 90 cm, though it can grow taller under optimal conditions. Its distinct lanceolate to oval-shaped leaves, measuring 5 to 15 cm, are a hallmark, often exuding a refreshing basil-like or balsamic scent when bruised. The leaf margins are finely toothed, presenting a dark green and somewhat glossy surface. During the summer, Costmary showcases clusters of small, button-like yellow flowers, each about 1.5 to 2 cm in diameter, atop erect, branching stems that possess a slightly rough, green texture.
These discoid, hermaphrodite flowers are characteristic of the Asteraceae family. The plant develops fibrous, thin, and ramified roots. Originating from western Asia, including Asia Minor and Australia, Tanacetum balsamita has successfully naturalized across various temperate regions, particularly in southern Europe, and was later introduced to North America by early settlers. It thrives in open grasslands, meadows, and forest edges, demonstrating a remarkable adaptability to a range of well-drained soils—from sandy to clay—and preferring mildly acidic to mildly alkaline pH levels.
While it tolerates semi-shade, full sun encourages prolific flowering, making it a versatile addition to gardens and naturalized landscapes. Its robust nature also allows it to withstand various abiotic stresses, including high temperatures and salinity.
