Here I am offering spores from the Dicksonia fibrosa also known as golden tree fern, whek? ponga, Woolly tree fern, Jade Green tree fern, or kuripaka. These spores are very small. They can be rinsed out of bag with water. Do this 3 times over soil. This medium sized tree fern is a native of southern New Zealand and known for its rusty looking trunk. WARNING These spores are like dust and you may have to dig out a magnifying glass to be able to see them. Dicksonia fibrosa can survive temperatures down to 12F or -11C. USDA Hardiness Zones 9 to 10
