| | Ornithogalum--PBS TOW |
 | | All these species can withstand at least a few degrees of frost, and some (e.g., nutans, orthophyllum, ponticum, pyrenaicum, umbellatum) are undoubtedly hardy to at least zero F/minus 18 C. umbellatum, commonly called "Star of Bethlehem," is naturalized in parts of the USA. |
 | | The green O. pyrenaicum is very easily grown and appealing as a curiosity. |
 | | In summary, the Eurasian ornithogalums, all white or green flowered, fall into three general groups in terms of form: short ones, tall ones with broad racemes, and tall ones with long, slender racemes. |
