Kousa, I haven't had any luck with Green Halo or Green Lotus, Pink Spritzer bloomed last year as did Circus Circus and Pink Rumba. Those 3 are pretty much the same flower just with more pink in the background (Circus Circus) and brighter pink splotching. Flowers are about the same size for me anyway and not much noticeable fragrance.
I moved Green Halo and Lotus this fall to full sun, think they were shaded too much by the house where they were planted. Hopefully I'll have blooms next spring!
