A dwarf by any other name...

You can see these beauties in force along the road. Dwarf White Honeysuckle is the common name I prefer for Justicia longii, but they are also known as Longflower Tube Tongue. (Yeah, right.) Only found in AZ and TX (in the U.S.), according to the USDA.
Not found in Riga.
