A year and a half ago I moved my N. caerulea from a crowded smaller pot to a 3’x1’ pot. I kept it in a sunny position, hoping that the insolation would compensate for the cooler temperatures we get here on the hilly spine of the S.F.Peninsula. This spring I moved it to a somewhat less sunny location, and changed its fertilizer from Dr.Earth5-5-5to Osmocote (slow-release 14-14-14). The result is that the plant has shot up to over 5½’and is blooming like crazy. For over a month it has been producing between 7 and 33 blossoms once or twice a week. I think its season is coming to an end – today there are only 7 blossoms; usually there are more than 20. Another thing I notice is that the scapes with many flowers bear no propagules, however last year’s scapes do. N. northiana didn’t fare nearly as well: this summer has generally been cool; the plant may require the fuller sun or greater warmth. However it bears many proagules, some of which have spread into other pots. At one point I tried crossing the two (during a period when their blooms overlapped), but the cross didn’t take in either direction. Neither plant has ever produced seed. David E.
