Osmanthus Fragrans Papers

Posted by ocelaris 7a (My Page) on

Just doing some research on Osmanthus Fragrans and wanted to share... I've read just about every osmanthus thread on gardenweb, so thought I'd start doing my own research. Hope people find this useful... My main goal was to find out any varieties which were a bit more cold hardy, and varieties in the Auranticus "DanGui" group may be the most cold hardy... Anyways, I've been collecting these links for later reference and thought I'd share.

Gui Hua is Mandarin for O. Fragrans, Kwai Hua is Cantonese for Gui Hua.

Daxin's explanation of Osmanthus:

"Guihua in Guilin can be divided into four sorts: Jingui (Osmamthus fragrans var. thunbergii), Yingui (Osmanthus fragrans var. latifolius), Dangui (Osmanthus fragrans var. aurantiacus) and Sijigui (Osmanthus fragrans var. semperflorens). "

Luteus, Albus, Aurantiacus, and Asiaticus group

A study on cold Resistance of Osmanthus Fragrans

"The northward distribution of O. fragrans may be
limited primarily by low spring temperatures rather
than low winter temperatures. O. fragrans Sijigui and
Huangchuan Jingui are the most cold resistant O.
fragrans cultivars in Kaifeng."

Thanks so much for sharing this with us!

I bought Osmanthus x fortunei (a hybrid of O. fragrans and O. heterophyllus) in December.
I'm hoping it will bloom for me this fall.
It's supposed to have a more gardenia like scent but is more cold hardy than O. fragrans.

Of course I've been enjoying the scent of my ‘Fudingzhu’ but I know it's not cold hardy so I welcome any varieties that are! :)

No problem, do you know if your x Fortunei is either Fruitlandii or San Jose etc... ? I'm just wondering how x Fortunei compares to Fragrans, and how the x Fortunei varieties compare to each other... It seems that x Fortunei would benefit for some more back crossing, Or recreating that cross with a Four seasons Fragrans variety.

Here's my collection of where they're for sale currently:

Nurseries Caroliniana (Lots)

Camellia Forest Osmanthus offerings (Lots)

Cistus's Osmanthus Offerings (quite a few)

Forest Farm (quite a few)

Lazy S's Osmanthus offerings (a couple)

Logee's (one or two)

I don't know. I wondered which variety I have when I did some research online.
I got mine on eBay from New Life Nursery & Garden.
It just states Osmanthus x fortunei.
They also carry some red and orange osmanthus varieties.

More Contributions, there are 4 groups, and here is a big list that I've compiled of various cultivars and which group they fall into. Basically Semperflorens (sijigui) are the variety that flower all the time, where as all others flower in the fall. besides color of the flower there are other differences which I am still deciphering. I know this list is daunting, but basically if you're looking to purchase a cultivar and you are not sure what characteristics or qualities it has, this will help for us non chinese speakers!

RE: Osmanthus Fragrans Papers

Wow, that's an amazing list of varieties.

Osmanthus 'Fudingzhu' was the only plant that I protected this past winter (bamboo stakes wrapped with burlap) but it was killed to the ground. It's coming back fairly nicely now. Osmanthus x fortunei 'San Jose' and 'UNC' were undamaged.

RE: Osmanthus Fragrans Papers

Yes, Fudingzhu is in the Asiaticus/(semperflorens)/sijigui category and is one of the least hardy of all. The x fortunei is a cross between O. Heterophyllus and O. Fragrans, and are hardy in your zone. The Auranticus/Dangui varieties are the hardiest of the O. Fragrans group. I have 2x Auranticus in my yard and we will see how they do this year. I plan on wrapping them the first year or two to cut down on desiccation.
