my lowii is in bloom. Finally ! Its been about 3 years and the trick seems to have been to have it outdoors for most of Summer. Its been through the wind, rain and highs in the 100's and lows in the 50's. In fact this is such a surprise that the spike was about 6in long before I even noticed it.....
The bloom is spectacular, but I'm not impartial as I have always loved these.
