A Prickly Pear Dilemma To Clean Up Pollution : Discovery News

A Prickly Pear Dilemma To Clean Up Pollution : Discovery News | Invasive plants | Scoop.it

The soils of the San Joaquin Valley in California have a dirty secret. They contain deposits of the element selenium left by the evaporated ancient sea that once covered the now semi-arid landscape. As humans put the land into cultivation, irrigation can wash that selenium into waterways were it can be toxic to wildlife.

The prickly pear cactus can provide a natural remedy to this poisonous problem, however using non-native plants to solve problems can be a double-edged sword.

Beyond Flowers – Native Ferns for Form and Function

Beyond Flowers – Native Ferns for Form and Function | Invasive plants | Scoop.it

So much of plant appreciation is focused on flowers that we sometimes forget to appreciate plants that exist in our landscape as foliage. Native ferns are true non-flowering plants – they reproduce by spores, not by the seeds/fruits that come from flowers. The spores can be found on the back of the fertile fronds or sometimes on distinctive fertile fronds (think Cinnamon fern). In fact the arrangement of spores is so special and unique on different ferns that you can identify them from the patterns.
