I just got my first sarr from english gardens, a reputable plant nursery near me. It appears in good condition and is labeled S. "Danas delight". I'm wondering what species it is and if it would be okay in a bog garden I just finished. It would be in the center of the bog at a slightly lower elevation from the surroundings (in the center so it doesn't shade the other plants). How much will it spread and how big will it get? It was being grown in full sun which is also where my bog is.
