A. Flowering Plants

More extensive information on flowering plants can be found in a separate blog post.


This ubiquitous, diverse family includes annual, biennial, and perennial species, terrestrial and aquatic species, and deciduous and evergreen species. One reason why grasses are such successful plants is that they grow from the base, whereas most other plants grow from the tip. This means they are more likely to survive when damaged, for example by mowing, grazing, or fire. 70% of all crops are grasses, producing grains for food.

C. Barren Brome (Anisantha sterilis)

Flowering from late April, this long-awned annual or biennial grass has loose, drooping panicles with rough branches longer than their spikelets.
