Costus spicatus, also known as spiked spiralflag ginger or Indian head ginger, is a species of herbaceous plant in the Costaceae family (also sometimes placed in Zingiberaceae). [1]
Costus spicatus is native to the Caribbean (including Dominica, Guadeloupe, Hispaniola, Martinique, and Puerto Rico). [1] [2] [3]
Costus spicatus leaves grow to a length of approximately 1 ft (30 cm) and a width of approximately 4 in (10 cm). It produces a short red cone, from which red-orange flowers emerge one at a time. [4] In botanical literature, Costus woodsonii has often been misidentified as Costus spicatus. [5]
Costus spicatus will grow in full sun if it is kept moist. It reaches a maximum height of about 6 to 7 feet (1.8 to 2.1 m). [4]
Costus spicatus can develop a symbiotic partnership with certain species of ants (often only a single species of ant will be compatible). The ants are provided with a food source (nectar in C. spicatus flowers) as well as a place to construct a nest. In turn, the ants protect developing seeds from herbivorous insects. [4]
In Dominican folk medicine, an herbal tea made from the leaves of C. spicatus is used for diabetes (hyperglycemia). However, a 2009 study concluded that C. spicatus tea "...had no efficacy in the treatment of obesity-induced hyperglycemia." [6]

Lamium galeobdolon, commonly known as yellow archangel, artillery plant, aluminium plant, or yellow weasel-snout, is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant. It displays the zygomorphic flower morphology, opposite leaves, and square stems typical of the mint family, Lamiaceae. The flowers are soft yellow and borne in axial clusters, with a prominent 'hood'. It spreads easily and so has been commonly used as an ornamental ground cover. It can be invasive in places where it is not native and caution must be taken when planting in these areas.
Acanthus is a genus of about 30 species of flowering plants in the family Acanthaceae, native to tropical and warm temperate regions, with the highest species diversity in the Mediterranean Basin and Asia.
