This seems easy to grow--it's my first and only gardenia and I've had it for a couple years. I have it outside, in full sun on the south side of my house in my naturally extremely sandy soil. It gets supplemental watering only during severe droughts--I basically don't mess with it other than raking in one "dose" of Hollytone around it in the spring. It seems to have a fairly short flowering period, but it is a handsome evergreen shrub that smells like heaven when it does bloom. I am planning on taking cuttings this spring to spread more of this plant around my yard.

Frostproof gardenias have done really well for me in New York City. Mine survived one winter that went down to 5F and still look green today after a low temperature of 12F this winter in early January. I get lots of blooms in late spring and sometimes I get scattered blooms in the summer as well. I dont give it any extra care.
It seems like they start to get light damage below 10F, but bounce back well making them great in zone 7 and up.

I planted the Frostproof in March 2011. The location I chose to put it in was partial to full shade and as of August 2011 it has done very well. I water it lightly every day and it has been happy with that. Living in the deep South I only have to worry about the cold temps that can hit my area (which can hit in the low 20's) so I won't know until Winter time how bad it can be bothered by the cold. I am hoping with it being planted under a canopy of oak trees that it will be okay. It flowered once for me this Summer and the flowers were pretty. I love Gardenia plants and have several of the Mystery Gardenia also and they have done very well and gotten large.

This plant performed quite well for our nursery in our display gardens for the past three years. It does discolor a little bit during the winter but has still survived even in an unprotected location. Blooming is heaviest in early to mid-June with a light sprinkling of repeat blooms through summer.
