Is it dangerous and how can it be removed?
It looks like tree lichens and they are harmless and don't need to be removed.

We have three small stems where the blooms were last year. leave them or snip them off
I don't know what plant you overwintered but chances are good they need to be snipped to the soil line to make way for new growth.
the plant was doing well then the leaves started to turn brown around the edges and eventually turn all brown and die. I do not know the name of the plant. It's leaves grow from the base and there will be a single large orange yellow flower in late summer. Do you know the name of this plant?
Unfortunately, your photo did not come through. I will not be able to offer any help without seeing the plant, or knowing exactly what it is.
I have a high elevation property in Colorado. It's roughly at 9500', I tried to transplant a couple Aspen that lasted only one year. I see other Aspen nearby so know they can grow I just wonder how to give them the best start possible as we do not live there full time. Also do you think a "Fat Boy Spruce" will also survive at the same elevation?
I would say that it can survive. Especially since you have seen, at least, one in the area. These articles will offer the best care information:

This article will suggest a tree that will do quite well in high elevation regions:

Many conifers will do well, as long as you stay within temperature tolerances of the species of your choice. This article will help:

Majesty Palm (Ravenea rivularis), Mass Cane (Dracaena Fragrans 'Massangeana') , Cordyline Fruticosa and a Dracaena Corn Palm.
All of these plants have similar requirements and care, fortunately. pH will be ideal in the "slightly acidic" range. 6-6.5 is idea, but they can tolerate neutral soil.
Moisture will fluctuate, if you want them to be healthy. It should go from saturated to almost dry, down to about 3 to 5 inches, which is where all of your beneficial bacterial will be. This is the important soil layer. You never want this layer to remain wet or dry, and it must fluctuate to be healthy.
Otherwise, here are some articles that will help:

I have asked around about what could cause this Anni get a different answer please help her....
It is likely growing upwards trying to reach the light. Make sure her plant is in the right amount of light for the plant.
Dear Sir, I have a small greenhouse growing microgreens. It is 16ft (w) x 8ft (w) x 8ft (h). 10mm double wall polycarbonate sheeting slipped into aluminium frames. It has 4 roof vents and one 4 ft door. I also have 2 air circulation fans. They can be mounted high in the green house. I think that I need floor vents to pull cool air from shaded areas around the base of the green house. The frames for the polycarbonate panel are approximately 24 inches apart. Can you advise if you have a shutter and fan mechanism or a louver system that could be put into a space cut in the polycarbonate.
