Orbella's new Fragrant Moss is bioengineered to smell like patchouli (earthy and spicy), linalool (floral and fresh) or geraniol (rose-like and bug repelling). "Orbella Fragrant Moss is a line of home fragrances cultivated in a glass terrarium. Using nature’s simplest ingredients — sunlight, CO2, and water — Orbella delivers a safer, cleaner, greener alternative to chemical-based air fresheners. No solvents. No phthalates. No petroleum by-products. Just fragrance made the natural way." If you're seriously interested, you might also note that "Current purchases will be eligible for a free upgrade (moss only) to the new enhanced fragrance strength strain of the moss when it's available." $79 at Orbella, found at Geek.com.
