Description: I'M JAMIE CSIZMADIA. Olthia is my garden design business - I design indigenous landscapes and sustainable, custom spaces for discerning folks. What I really dig are the places where people and nature, get all mixed up in each others “business.” Like when a wild, untamed Oklahoma sunset – settles over the pretty little yards of a pocket neighborhood. Or when a concrete walking path finds itself curving into an unexpected city garden. When an outdoor gathering space can feel modern and bright, but still captivate and calm us with nostalgic little surprises – THAT'S MY PASSION. I SPECIALIZE IN NATIVE OKLAHOMA PLANTS. It’s a “new prairie” approach where plants native to this land meet the world outside your back door (especially that small, stubborn piece of it that you just can’t figure out what to do with.) And to be honest, at the end of that day, if the outdoor spaces we’ve carved out aren’t people spaces, too – then they’ve only met half their purpose.
