2" single, fragrant ivory flowers blooming in late spring into summer; lustrous dark green leaves. A slow growing, low mounded evergreen reaching 2 to 3 feet high and wide. Mine has been growing in a pot on my roof for two years, I do not bring it in for the winter and is doing very well.

I have only one stock plant that I put in the greenhouse in the winter months. I have about 16 cuttings that are doing very well. they were transplanted into 3" pots 10/3/07. The stock plant is not looking too happy just now and I am concerned that it is too warm in the greenhouse for it. On the other hand, it is much too cold to keep it outside. Time will tell.
Our weather has been very unsettled and it is difficult to keep the greenhouse at a steady temp.

A fragrant, very hardy single-flowered variety of gardenia. Worth a try with protection as far north as Southern Ohio. Likes kept moist, can burn in too direct of sunlight, can tolerate salt and less-than-perfect soil.

UPDATE MAY 2007:

I am VERY excited! Today I have a green bud. With adequate siting, attention to microclimate, and mulching of the roots, Kleim's Hardy is root hardy to north central Ohio. -8 F, and a blizzard. Today I still have a gardenia. This is one tough plant! :)

I have 2 plants growing in pots. They're both not blooming now as I think it is too hot this time of the year. I have them indoors for the winter the last 2 years but I am planning to put them in the ground next year. I've seen some plants in my neighborhood and they seem to survive the frost in the winter. However they tend to become very bushy.

Reliably hardy, evergreen small shrub. Blooms are smaller than florist gardenia. Fragrant blooms add a tropical feel to a temperate garden. My plants have survived snow, frost and temperatures down to -10C in containers.
