Gardeners' Notes:

I found this plant in the woods of Northeastern Pennsylvania at the end of January, already producing its yellow strobili. They were so perfectly compact and seemed like they might do well inside. I collected 2 plants, one with it's rhizome intact, the other just a shoot, and planted them in a terrarium (in medium light) with some mossy bark I gathered from the same spot. Almost 2 months later and it's all growing beautifully together. The shoots began to develop their yellow tips within a month.
In my opinion, this is a pretty hardy plant.. Although I was careful with them, I was an hour away from home visiting family and they spent 2 days with just their roots tucked into the moss before being planted and they never even drooped!

We would be paid approximately 4 to 8 cents per pound, depending on the annual market price. After school I could easily pick 35 or 40 pounds but on a Saturday, 70 to 90 pounds was common. I would love to purchase some princess pine now but every where that I have found the "real" princess pine for sale, it is much too expensive. Most websites I ... read more
