longriver,
I have a hughe sweet olive tree in a big pot that I take outside every May until October, then I bring it inside for the winter.
In November, it starts to bloom and the smell fills the whole room it is in. It is potent.
This year, it actually bloomed heavily til the end of June.
It was full of flowers from November through the end of June. Smelled great!
I am going to have to cut it down for this fall though, it is getting too big for me to carry up the stairs in the cold weather.
I'm sure it will be OK. It is definately worth the trouble when it starts to bloom all winter and it smells like summer.
Love it!

Butterfly4u:Thanks for your information: I am collecting a few varieties of O.manthus. Did you purchase your Sweet Oliver locally? Do you have any information about your cultivar? American native Sweet Oliver has a long blooming time. If you are in cold area and also fool the nature by placing the plant indoor; which might extend the flowering duration.

Quite a few fragrant winter blooming things for SF Bay Area gardens. Jasminum polyanthum/Pink Jasmine for one, Daphne odora, Paperwhite Narcissus, Pittosporum undulatum and Pittosporum tobira can often bloom in winter here in Berkeley. Fragrant foliage to be brushed against at any season might include Coleonema pulchrum and Prostanthera ovalifolium, and if you have room for a large growing tree, the Lemon Gum/Eucalyptus citriodora, is wonderfully fragrant if you crush the foliage.

Osmanthus fragrans also easily blooms outdoors in winter here by the bay, so no need to bring it indoors.

My potted orange and lemon trees usually bloom in January. heavenly!

Great ideas! bahia and annebert
Yes I have a huge Daphne odor and many others. In Bay Area, we have more choice. I am at Orinda on the other side of hill.
