Catherine G.,
I doubt that that Brassica stem will be long-term durable for a walking-stick, not enough lignan glueing the cellulosic fibers, would split and delaminate. Ordinary wood is more durable (and least labor in stripping, staining, polyurethaning); perhaps the ultimate in flexible fracture resistance is cornelian-cherry (prized for drumming rappers, but hard to find in walking-stick sizes), for rigid strength hawthorn would be my choice (dense, but gives a fine pattern of limb-scar knobs). Most of my work is in sweetgum, it's the prevalent vine-wrapped species hereabouts (lightweight, easy to carve to shape). You are always balancing weight vs. durability!
Technical tip: for those pesky fibers that stick out after cross-grain carving: a quick pass high over a gas flame will flash them off without changing the main stick surface.
