My husband and I are in Portugal for vacation. We've just spent a wonderful afternoon with Uli Urban, and his partner Bernard Niederberger, touring their garden in southern Portugal. They welcomed us so warmly and were happy to answer our questions. They transformed a weedy steep slope into terraces heavily planted with unusual bulbs, succulents, orchids, shrubs, and fruit trees. What they've accomplished is awe-inspiring and simply beautiful. Uli told me that he would enjoy having more PBS members visit him, so reach out to him directly.
