Cold Stratification

There's been little activity with my coffee filter baggie seeds in the past couple of weeks, so I'm trying cold stratification. Germination rate in coast redwoods will increase when their dormancy period is overcome by extended periods of near-freezing temperatures. I've moved the seeds into baggies of moist seed-starting soil (mostly peat moss) in my refrigerator. In two months, I'll remove them from the cold, and keep the baggies out in the open where they may receive indirect sunlight. When the seedlings start germinating, I'll move them into their own cel-packs.

I wrote a more detailed post on cold stratification and the soil baggie method in my giant sequoias blog, if you're interested.

Seed #4 - Three Cotyledons

Most of my coast redwood sprouts have two giant cotyledons. This one sports three.

Seed #16 - Sprout

Seed #10 - Sprout

Another healthy sprout.

Seed #7 - Sprout

Seed #7 is starting to show its cotyledons (seed leaves).

Seed #3 - Sprout

I'm so used to my giant seqouoias' three to four cotyledons that I'm still surprised when I see only two emerging from my coast redwood seedlings. While the giant sequoia seedling generally has between three to five cotyledons, two is normal for the coast redwood.

Seed #7 - Sprout

Not much to tell here - just a healthy coast redwood sprout making its way through though the soil

Seed #1 - Sprout

It's always nice to see a seedling sprout without its seedcoat.

Seed #16 - Radicle

Seed #15 - Radicle

Seed #14 - Radicle

Seed #13 - Radicle

Seed #12 - Radicle

Seed #11 - Radicle

Seed #10 - Radicle

Seed #9 - Radicle

Seed #8 - Radicle

Seed #7 - Radicle

I really didn't expect so many coast redwood germinations so quickly. This is one of ten I found this morning.

This is not a Coast Redwood Sprout

Okay, I thought this was my first sprout, but it turns out to just be a blade of grass that grew from a seed that found its way into my seed-starting soil.

However, I'm not letting these photos go to waste :)
