The personable partners of Bixa — Charles Pitchford and Darrel Dewitt — returned to Denver after a long stint in Aspen to open their tiny new storefront on Colfax. It's named for Bixa Orellana (an Amazonian plant identified by its red-orange stones, better known as Annatto seeds), and for their so-monikered cat. But the front is painted purple, and that paradox is just one of the many rare delights this retail anomaly brings to the street. What's in Bixa? It's a biodynamic/recycled paradise, the future of the corner drugstore, where every item on every shelf is sustainable in some way, from the high-end (and beautiful) South African telephone-wire baskets to cheaper pleasures, including all-organic fruit-flavored hot-chocolate mixes and cinnamon cotton candy. But the core product of the store — which is divinely littered with bracelets made from linked lapel buttons, necklaces of rolled-paper beads, pop-top wallets, bottle cap lamps and aromatic rose syrup — comes from Intelligent Nutrients, offering organic and healthy "nutraceutical" foods and supplements, infused flower waters and more.
