Seed #4 - Eight Cotyledons

So far, I've seen anywhere from four to eight cotyledons. These little guys are so aggressive to sprout, but in adulthood, they'll grow very slowly. In the wild, they may live thousands of years old, and stay relatively small.

Seed #1 - Seven Cotyledons

For as little as I expected from my bristlecones, they've really impressed. They shoot long, rigid radicles, sprout aggressively, and open up between five to eight cotyledons, all within a couple weeks.

Seed #16 - Outside Seed Sprout

As with seed #15, this little guy really surprised me. I had all but given up on the outside seeds, switching to the indoor baggie method for the rest of my bristlecone seeds. Apparently they're not doing as badly as I thought. I guess I shouldn't be surprised - bristlecones are known for drought tolerance and growing in unforgiving climates. It was interesting to see five cotyledons too - I haven't seen this with any of my other tree seedlings yet.
