Episode 8: Phenology Throwdown for April 2018

 

Spring is here, and this month’s Phenology Throwdown reflects that. We start by talking about trees. The large, showy flowers of magnolias are hard to miss, but there are lots of other trees in bloom with less showy flowers. Several tree and shrub species produce catkins – long, narrow, spikes of flowers that can be seen dangling from branches. The flowers of catkins are wind-pollinated, so blowing in the breeze helps them dislodge their pollen.

Casey reports on some native plants in bloom, including golden currant and Aase’s onion – a rare, endemic onion that you can find in the Boise Foothills. Check out this list for more native and rare plants you can find there. Daniel also mentions a few flowering weeds, because weeds are plants too, after all.
