Although retired is a relative term, I doubt I will get energetic enough to start a farm . But to keep sort of on topic, a greenhouse could be put to good use in that environment. Up on White Mountain (CA east of Bishop) high schoolers have grown crops in small boxes above 12000 feet. If you design it right, you can maximise heat storage in the colder months using passive solar ideas. Or you can just grow 4 tomato plants in a box with a cover on it like the kids did in the White Mountains. I is just up to how carried away you want to get. But you might have to really think about the layout in terms of sun direction and angle. Anyway, I would probably just go for some fruit trees, lots of berry bushes, and a 15x20 foot greenhouse. After that, I think your bulb garden sounds pretty cool along with native plants.

I was curious about the pioneer aspect as there is a pretty substantial Polynesian community in Bend.
