Here are a few pics from October 2010, from a visit to Mt. Diablo (near San Francisco).

Pinus sabiniana, cones

There were cones laying on the ground all over the place, and I took a couple home.
The cones on this tree are large, compared to many Colorado pines.
Pine cone lineup: ponderosa, flexilis, sabiniana, contorta, aristata

The seeds are large too.
Seeds: top row contorta (l) and aristata (r), center sabiniana, bottom row flexilis (l) and ponderosa (r)

This spring, I decided to try and germinate the sabiniana seeds from those cones.

I put them in a damp media mixture, and four weeks later one started to sprout.

RE: ghost pine

Very unusual for the cotyledons to push right through the endosperm!

The provenance for these seeds is Mt. Diablo, where according to Wikipedia the lowest temperature on record was 14 °F (-10 °C) on February 6, 1989, and on December 14, 1990. Lows of 32 °F (0 °C) or lower occur on an average of 15.4 days annually

RE: ghost pine

Had a few cold days in December, 7 days with a lowest temperature of 14F (-10C) or below. The coldest was -6F (-21C).

This one seems to be doing OK.

RE: ghost pine

Fingers crossed for sucess. I'm grafting a mugo at the moment and in a similar hopeful vigil.

RE: ghost pine

Thanks Severnside! Good luck with the mugo, what kind are you grafting, and what are you using for understock?


 o
RE: ghost pine

I took a scion from a choice mugo of no formal recognition at a local industrial park. The understock is unknown perhaps contorta species. One I plucked as a seedling from a welsh planting a year or two ago. They married up nicely, both parts very fresh and juicy, but I've only left it outside and in the garage in ambient temperatures (luckily no freezes, fairly mild). It's still pristene at six weeks but in winter a dead branch can look such at six weeks. Still the buds look very viable and I dare to hope.

RE: ghost pine

Nate, here's a couple of terrible low-light close ups from today of the buds for rough analysis. There seems to be life in them would you say? At seven weeks is this a good sign or can they still be blissfully unaware they are amputated?

Severnside, I don't see anything wrong with those. Hope you get good results this spring!

RE: ghost pine

One would think that Mt. Diablo provenance would be one of the least hardy but then, "logic" often fails!
