Chromolaena odorata

''Chromolaena odorata'' is a tropical and subtropical species of flowering shrub in the sunflower family. It is native to North America, from Florida and Texas to Mexico and the Caribbean,〔(【引用サイトリンク】 Chromolaena odorata )〕 and has been introduced to South America, tropical Asia, west Africa, and parts of Australia.〔(Flora of China, 飞机草 fei ji cao ''Chromolaena odorata'' (Linnaeus) R. M. King & H. Robinson )〕〔(Tropicos, ''Chromolaena odorata'' (L.) R.M. King & H. Rob. )〕〔(Atlas of Living Australia )〕
Common names include Siam weed, Christmas bush, devil weed, camfhur grass, common floss flower and triffid.〔Lalith Gunasekera, ''Invasive Plants: A guide to the identification of the most invasive plants of Sri Lanka'', Colombo 2009, p. 116–117.〕
==Description==
''Chromolaena odorata'' is a rapidly growing perennial herb. It is a multi-stemmed shrub to 2.5 m (100 inches) tall in open areas. It has soft stems but the base of the shrub is woody. In shady areas it becomes etiolated and behaves as a creeper, growing on other vegetation. It can then become up to 10 m (33 feet) tall. The plant is hairy and glandular and the leaves give off a pungent, aromatic odour when crushed.
The leaves are opposite, triangular to elliptical with serrated edges. Leaves are 4–10 cm long by 1–5 cm wide (up to 4 x 2 inches). Leaf petioles are 1–4 cm long. The white to pale pink tubular flowers are in panicles of 10 to 35 flowers that form at the ends of branches. The seeds are achenes and are somewhat hairy. They are mostly spread by the wind, but can also cling to fur, clothes and machinery, enabling long distance dispersal. Seed production is about 80000 to 90000 per plant. Seeds need light to germinate. The plant can regenerate from the roots. In favorable conditions the plant can grow more than 3 cm per day.〔Lalith Gunasekera, ''Invasive Plants: A guide to the identification of the most invasive plants of Sri Lanka'', Colombo 2009, p. 116–117.
