?一品紅葉子特寫(xiě) 在國(guó)家一品紅日，我們將近距離觀(guān)察一品紅的葉子。盡管許多人認(rèn)為紅色、白色、粉色、紫色或大理石花紋的顏色是花，但實(shí)際上它們是苞片，一種有助于繁殖的葉子，通常是在植物長(zhǎng)出真正的花朵時(shí)變色。在一品紅上，苞片包圍著一種名為cyathia的黃色叢生小芽，它像花瓣一樣把傳粉者擊倒是的。還有當(dāng)我們談?wù)撘黄芳t的時(shí)候，讓我們驅(qū)散一個(gè)關(guān)于這種令人愉快的節(jié)日植物的黑暗神話(huà)：它們對(duì)兒童和寵物沒(méi)有致命的毒性。早在1971年，俄亥俄州的一項(xiàng)研究表明，一個(gè)50磅重的孩子要吃大約500片葉子才能看到任何不良影響。那些不良影響？我們就說(shuō)它們是胃腸道的品種，就這樣吧。

On National Poinsettia Day we're taking an up-close look at a poinsettia leaf. Although many people assume the red, white, pink, purple, or marbled colors are flowers, they're actually bracts, a type of leaf that aids in reproduction, usually by turning color as the plant develops true flowers. On the poinsettia, the bracts, surrounding small yellow clustered buds called cyathia, flag down pollinators just as flower petals do.And while we're talking poinsettias, let's dispel a dark myth about this cheerful holiday plant: They are not fatally toxic to children and pets. Way back in 1971, an Ohio State study determined that a 50-pound child would have to eat about 500 leaves to see any ill effects. Those ill effects? Let's just say they're of a gastrointestinal variety and leave it at that.
