Dave,
Good questions!
So, basically, we are packing for a one-way trip to Mars, and we can only bring five plants? How about 1) onions for food, flavor, and medicine, 2) a starchy tuber, such as potatoes, yams, or sweet potatoes, 3) if I could only eat one fruit en masse, I would have to go with bannanas, 4) how about avacados for food and rich oils, and 5) some kind of salad green... maybe
dandelions for food and nutrition. What's your five?
Favorite plants from different climates:
I don't have much
experience with tropical climates, but I do have a nice
greenhouse on the front of my house, which includes orange
trees, hibiscus, grape vines, a bannana (no fruit yet), guava vine, passion flower, lots of herbs, gernaniums, and a seven-foot tall Mexican marigold which smells amazing. I really like it when the orange trees bloom. It makes the house smell so good!
A few of my favorite plants here in Montana include saskatoons (service berries), cattails, and whitebark pine nuts... actually pretty much everything that's included in my book Foraging the Mountain West:

Okay, skipping to most fascinating plants:
Eaten: I've been pretty fascinated by hawthorns lately. We did a foraging
class at Rabbitstick Rendezvous in September and harvested a bunch of black hawthorns. We then squeezed the pectin out thorugh a screen, separating it from the seeds. There is so much pectin that the juice solidifies on the edge of the container without running all the way in. For the fruit portion of our meal, we ate chunks of hawthorn berry pectin.
Grown: I live in a cold desert. I've grown increasingly fond of plants that have Siberia in the name, notably Siberian elms and siberian almonds. Siberian elms are invasive in many places, but that isn't a risk here. However, they do seem to thrive with minimal moisture in places where it would be challenging to grow anything else. And my Siberian almonds are only two feet tall, but already producing some small, fuzzy, bronze-colored almonds.
Seen: Probably elephanthead lousewort (Pedicularis groenlandica). See attached. Cool flowers, huh?
Used: Probably birch bark for containers and fire-starters. The resins make the bark behave in such unnatural ways.
Sincerely,
