Advocate story June 16, 2014 Comments The 62-year-old Harb has been designing ponds for two decades and has created gardens since the 1970s, when he trained as a landscape architect at LSU and opened his business, Harb’s Oasis. He created the annual Tour of Ponds and Gardens 15 years ago to showcase some of the most interesting water features in town. This year’s pond tour begins Saturday. Harb says the size of his pond and garden cannot compete with some of the large, lavish gardens he creates for wealthier clients, but his yard has been designed to use every square foot of space. The yard features more than 300 varieties of plants, arranged so that something is nearly always blooming. There’s Queen Elizabeth lilies with gorgeous white flowers and green parrot’s feather plants growing in a red pot on top of his waterfall.
