Tamasudare that is often seen in shrubs by the road is also Rain Lily. Habranthus in the photo and Saffron Modoki are also Rain Lily. In other words, the flowers of the Higanbana family which extend through the flower stalks when the bulbs become moist due to rain after drying and high temperatures, are collectively called Rain Lily. Although all these flowers look pretty and neat, the plants of the Higanbana family, including Rain Lily, contain deadly poisons such as lycorine. You often say, “Beautiful flowers have spines.”, don’t you.
道の植え込みなどによく見かけるタマスダレもレインリリーです。写真のハブランサスやサフランモドキもレインリリーです。つまり、乾燥と高温の後に雨が降って球根が潤うと花茎をのばして開花するヒガンバナ科の花を総称してレインリリーと呼びます。どの花も見た目には実に可憐で、清楚な感じがしますが、レインリリーも含め、ヒガンバナ科の植物にはリコリンなど猛毒が含まれています。「美しい花には刺がある」とよく言いますが。
