I'm bark, but I'm not a dog's sound. I sweeten, but grow on a tree. My scent can unlock Christmas memories. What am I?

As our daily friend sinks away, resting to come another day, Up in the sky, vibrant hue hovers, setting the stage and cue for lovers.

I am not a blanket, yet I cover the ground; a crystal from heaven that doesn't make a sound. What am I?

I help plants climb up toward the sky, I’m like a wall, but holes go by. I’m criss and cross, a wooden net, What am I that flowers can’t forget?

If you are too lazy to solve this riddle, you may be exhibiting a deadly sin. The giant ground ones went extinct ten thousand years ago.
