This spring I ordered my first Brug, Ecuador Pink, and Parks sent me Cherub instead. No reason given for the switch, but the plant did look healthy to me so I did not complain. I didn't realize that it was a new introduction until I searched this site. Two questions, please: How long might I have to wait to compare notes on the blooms with the rest of you? Will I have more success if I train it as a single stem or should I leave it as is with two "branches"?
