Warneck dracaena (Dracaena deremensis 'Warneckii')

Combat pollutants associated with varnishes and oils with this dracaena. The Warneckii grows inside easily, even without direct sunlight. With striped leaves forming clusters atop a thin stem, this houseplant can be striking, especially if it reaches its potential height of 12 feet.
