The plant browned severely then but over 2 years grew back from the base and is now its full 4 ft height. It sustains some browning every winter on the exposed side of the plant. So do not prune, except to shape after flowering, until spring, to cut off any damaged branches, then. In early summer here it blooms extensively for about a month, with the expected pungent sweet aroma. And the glossy deep green foliage contrasts well against the roses and spirea around it and has made an excellent foundation planting.

After the cold winter of 2008/2009, my "Grif's Select" Gardenia was still 90% green by spring. I have it planted in a sheltered location with southern exposure but some of my other "hardy" gardenias had similar micro-climates and did not do as well.
I purchased it from Gardens OyVey and followed their instructions for incorporating shredded pine bark and humus into my clay soil. My plant has acclimated nicely using their techniques.
One last thing about "Grif's Select" - it gets fairly large compared to some gardenias. 4 feet high and wide is not unusual.

If anyone has any tips, please post.
