The earliest flowering plants show up in the fossil record 130 million years ago. These beauties became the dominant type of forest plant by about 90 million years ago. One of their number, the genus Crocus, is a particular favourite of mine.
Crocus — the plural of which is crocuses or croci — is a genus of flowering plants in the iris family and includes 90 species of perennials growing from corms. A corm is a short, swollen underground plant stem that helps plants survive summer drought and other less favourable conditions. The name Crocus is derived from the Latin adjective crocatus, meaning saffron yellow. The Greek word for "saffron" is krokos, while the Arabic word saffron or zafaran, means yellow.
Many are cultivated for their flowers appearing in autumn, winter, or spring. The spice saffron is obtained from the stigmas of Crocus sativus, an autumn-blooming species.
