“All items arrived quickly and well packaged. I usually expect to have one or two live items out of a batch, but they are all thriving. I couldn’t be happier!”

“My live plants were packed like they belonged in Ft Knox. 😂 They really were packed beautifully. Only one plant, a bee balm, is questionable but signs that it will recover are happening. All in all I am thrilled with my plants and seeds. Some of my coreopsis have already sprouted!”

“I’ve ordered seeds from Whitwam Organics 3 or 4 times now. I love the simple packaging, clear planting guidelines, and variety they offer. Great germination rates!! The bare root plants I’ve ordered have come healthy, so healthy that the wild rabbits always approve of my menu upgrades! 😂🐰”
