Mystery Seed of the Week 69

I admit that these seeds will be very difficult to guess, but I wanted to tell you about the cool plant they come from, so here it goes:

Yes, these are really seeds.

They come from a plant that is found only in the Southwest and probably not too many people grow them.

Are you up for the challenge? What plant are these seeds from?

Edit:  The answer is now posted.

Seed of the Week: Eastern Hemlock

Seems like you may have been confused about last week’s mystery cones. I was actually hoping that someone would recognize the tiny cones as coming from Eastern or Canadian hemlock, Tsuga canadensis.

This hemlock is a common tree in the eastern part of North America. In fact, it is the Pennsylvania state tree.

The needle-like leaves are short (less than an inch long), flat, soft and have two whitish-colored lines on the underside of each.

Hemlocks give dense shade, cover and food to a number of different forms of wildlife, including deer.

The trees are able to grow in dense shade. In fact, the seedlings can not grow in full sun, so will not return to areas that are clear cut.

There was a seed in one of the cones I took a photograph of, but it doesn’t look viable. One article I read suggested that although hemlocks produce a lot of cones, few of the seeds germinate. In the article linked below, the authors suggest less than 25%.

Eastern hemlocks are used as ornamental trees, but require quite a bit of space. In the right conditions they will live over 400 years, and maybe up to 800 years.

In the past, hemlock bark was gathered for as a source of tannins used the the process of tanning leather products.

Do hemlock trees grow where you live? What kind?

For a map of where Eastern hemlocks are found and more biological information try:

Mystery Seed of the Week 68

Two hints this week. First, this is the “package” the seeds come in. Second, I didn’t find these in Arizona.

Sometimes they look like this.

And after you bring them inside, they look like this.

Do you know what the plant that produces these is called?
