Which plant genus includes more species, Hedychium or Malephora?
Hedychium Hedychium is a genus of flowering plants in the ginger family Zingiberaceae, native to lightly wooded habitats in Asia. There are approximately 70-80 known species, native to Southeast Asia (Thailand, Malaysia, Indonesia, the Philippines, etc.), southern China, the Himalayas and Madagascar. Some species have become widely naturalized in other lands (South Africa, South America, Central America, the West Indies, and many of the islands of the Pacific, Indian and Atlantic Oceans) and considered invasive in some places.
Heliotropium arborescens Heliotropium arborescens, the garden heliotrope, is a highly fragrant perennial plant, originally from Peru. It is especially notable for its intense, rather vanilla-like fragrance. Common names include "cherry pie" and "common heliotrope". Note that the common name "garden heliotrope" may also refer to Valerian (herb), which is not a heliotropium variety.
