You have to buy the red variety. It's not like the hydrangea you manipulate the colour :)

If you are looking for a good vibrant red variety, try a variety called (??)

Give them time - also there is a red and a green variety. Check which one you have, if you can by googling.

Don't plant it in plastic, they hate that. Use terracotta and it will do well. It likes the airflow. I have mine in a medium terracotta pot and it's loving it. You do have to feed and water it very regularly though in warm weather. It's not a set and forget situation potted up, needs some looking after. But does make a great display.

My guess is that your soil has too much clay content in it for rhubarb. It does this in heavy soil. I tried to grow it in the ground here, I have very rich, dark soil but it borders on high clay content. My plant suffered until I removed it and potted it up in large terracotta pot with light potting mix. Now it's doing brilliantly. The terracotta keeps the roots cool and stops the crown from rotting. But it has to be watered daily potted up like that as it wilts very easily. I ended up growing my rhubarb and strawberries in pots because they just didn't like the heavy soil. They are producing wonderfully now and make a nice display together. An alternative could be to add a lot of organic material to your soil and plant it into a built up mound for free draining situation.

Buy some sand or sandy loam soil and mix into your soil and compost.

Does rhubarb have to be out of sun lite? Can it grow here in San Diego?

Most plants need lots of sunlight. Check what Climate Zone San Diego is in the climate zone section here and look it up if you can grow it.
