How gorgeous! I’m on my third…if this one doesn’t make it I’m done and I’ll look for another yellow. At least that’s my story now. 🙂

I would submit this anecdotal observation in regards to length of daylight and the intensity. The Pinus sylvestris “Gold Coin” in my landscape is still turning to its full yellow as we approach Christmas. The “Gold Coins” that are growing in my nursery (pot in pot) are bright yellow now and have been for a month. They get the same amount and intensity of light. However, there are variables. The medium in the pots is a pine bark and it drains quickly. So the container grown is likely drier in the winter as opposed to the established plant in the landscape. It also will get colder at an earlier date without the insulation of roots in natural soil.

Interesting.
In my yard in Bend, Oregon today my Chief Joe is 90% yellow. My Gold Coin is probably 50% there. They are planted in the ground 20 feet from each other. My nearby Carstens Winter Gold is 30% yellowed.

The “golden effect” is obviously a genetic mutation. With the ability today to look in detail at specific genes, it would be interesting to know if the various conifer species that have “golden” cultivars/mutations all had the same mutation or if each species has evolved its own, unique DNA alteration.
Charlie Darwin would have loved this phenomenon!
