Saskatoon in graphite

This week's Illustration Friday prompt is perennial. I'm a little short on time right now, so here's a fifteen-minute sketch of saskatoon, a perennial plant (well, it's a bush, so by definition it's going to be perennial...) that bears fruits that are perennial favourites around here for preserves, syrups, and pie-making. Not quite ripe yet, but when they are I'll be raiding the shrub outside my office window for at least a few handfuls.

If I get around to it I'll try to post something a bit more substantial for the word later.
