A rose by any other name would smell as sweet.

(Wm. Shakespeare)
"Not if you call 'em stench blossoms." (Bt. Simpson)
"Or crap weeds." (Homer)

This stuff stinks but is annoyingly prolific in our garden - don't know what it is but it's known locally (very locally!) as Stinking Crap Weed. Flowers are nice though.
