BBY010 :: Sorghum halepense (?)

This is grass; I know that much! It is possibly johnsongrass, which I learned this week is an invasive introduced species that is not officially listed as present here in BC. However, if johnsongrass has popped across the US border, I wouldn’t be surprised. The plants I observed grow mainly in the marshy areas toContinue reading “BBY010 :: Sorghum halepense (?)”

BBY004 :: Alnus rubra

BBY003 :: Betula papyrifera var. commutata

Paper birch, western white birch. As we will see in next week’s post and still more to come, the first day’s expedition to track the species at Burnaby Lake was a bit naïve and ambitious. I correctly distinguished that entries 003 and 004 were different trees while out in the field; however, after reviewing myContinue reading “BBY003 :: Betula papyrifera var. commutata”

BBY002 :: Spiræa douglasii

Rose spirea, hardhack, Douglas spirea, steeplebush. Another member of the rose family (see 001 last week), this native bush produces beautiful fuzzy flowers all around the lake for much of the summer. I’ve seen red-winged blackbirds sitting in the dried upper branches eating the seeds. While native, bountiful, and beautiful in North America, this speciesContinue reading “BBY002 :: Spiræa douglasii”
