As of an update last month (https://secure.runescape.com/m=news/more-poll-78-changes?oldschool=1) harvesting belladonna provides a new, stacking variant of nightshade, which can be used to produce weapon poison++.
Unlike the old cave nightshade, the plugin doesn't count it as a source of herblore XP.
