Gardenia


According to the notes in my Have/Want book, Gardenia thunbergii is 
more tolerant of cool summers.  I haven't found one yet, though.

The ones I have are forms of G. jasminoides.  The ones that have 
flowered are small, really just rooted cuttings that I bought at 
Humber Nurseries in Toronto for about $2 each: j. radicans, j. 
radicans "Variegata" and j. "White Gem".

A larger one that hasn't flowered yet I bought at Gossler Nursery in 
Springfield Oregon: j.Klein's Hardy.  The poor plant got completely 
buried by a rampant salvia.  I'm hoping for blooms now that it is 
exposed to a bit of daylight.

I have them growing instead an unheated greenhouse which ranges in 
temperature from a low of 8C in the winter to a high of 30C if I 
forget to open the windows in the summer. When they are big enough, 
I'll take cuttings and try them outside.  This seems rash when I 
remember the large gardenia bushes lining the walkway at my seaside 
school in Sabah, on the island of Borneo.  The girls used to pick the 
blossoms and put them in their hair, and the boys used to prune the 
bushes with a parang (machete) against a piece of board as part of 
their chores.
So maybe I'll just try the Klein's Hardy outside.
