The official registered name for this plant is 'Lemon Drop', introduced by Elizabeth Thornton, and registered through the Plumeria Society of America. Some people have added the name 'Thornton' to it to differentiate it from another cultivar named 'Lemon Drop', which was improperly named, since the name had already been used and registered. The other 'Lemon Drop' is not at all like the original 'Lemon Drop'
The improperly named 'Lemon Drop' should be re-named to eliminate this confusion.
'Lemon Drop' as shown in the photo is a stunning large brilliant yellow flower with a small white border. It has a very compact form with pubescent branches. The leaves are a light green color. Fragrance is mild. I highly recommend this plant as being the best yellow plumeria.
