He could ask Sorrow for specific plants from his world, but he will have to be very specific about his descriptions, particularly if he intends to use them for a magical purpose. Sorrow will be creating the plants from scratch, not bringing them from Carlisle's world, so any error or omission in the description would be likely to make them useless for alchemical purposes.

However, if he did manage to describe them with enough detail, he would be able to use them to learn and practice alchemy, as well as teach it to others, provided it isn't too complex or reliant on magic from his own world.
