I have never heard of chocolate scented sunflowers but I love sunflowers! I am interested but I am not sure I have anything that would tempt you here. Please see my page and get back to me :) Michi

I ws two white varieties of Echinacea that have a nice fragrance, 'White Swan' and 'Fragrant Angel'. Not as strong as the phlox though. Expect you already have those. The only thing that has saved my phlox from the deer is Liquid Fence.

For osmanthus, Fudingzhu is the main variety that blooms intermittently throughout the year. It is not perfect, as in you won't have flowers constantly. There are probably other varieties that have better blooming, but it's a matter of finding them for sale (probably exists in China but impossible to get). Michelia alba will bloom almost constantly in tropical conditions. I would get two or more if possible because one plant may be in bloom and another one next to it might be "re-energizing" for the next flush of blooms. Michelia champaca in my climate blooms for a few months out of the year (California). If you can get ahold of the other yellow/orange michelia hybrids from Thailand you may see better, extended blooming. You may also want to check out Tahitian gardenia (can bloom year-round).

It's best to smell the roses in person, grown locally if possible. Strong is subjective, and different people may smell the same rose and have different impressions. For example I think Alnwick Castle is one of the strongest smelling rose in my garden, and can smell a single flower open from yards away, but my friends do not agree, and have to put their nose into the flower to smell it. Also, a strong smelling rose may not be a good thing. When I grew Glamis Castle, I found that it smelled very strong: of mothballs. Similarly with Wollerton Old Hall. Others have commented that GC smells like dirty diaper pails, and yet others say it smells great. When I went to Oregon, I smelled one in a display garden and it did smell great! Not like mothballs at all. Souvenir de la Malmaison is called "The Queen of Beauty and Fragrance" and yet many people find that it smells of beer, as I do. Not that you have any of these on your list, or any roses that some interpret as stinky, but my point is that if you can, sniff the roses before you buy them if you want a fragrance you like. Roses have a lot of variability in their fragrances. Different roses can smell like lemon, fruit, grapefruit, litchi, sandalwood, musk, honey, cherry candy, cedar, almond, peaches, violets, raspberry, plum, cloves... That being said, I find that Madame Isaac Pereire has a particularly well balanced fragrance, having a lot of depth and nuance. Louise Odier often smells like the plastic that they package clothes in to me. Another thing to keep in mind is that strong fragrance is not necessarily the same as wafting (the ability to smell it from a distance). I agree with Chris Martins Zone6a Chicago on this. For example, Marie Pavie doesn't smell that strong when I put my nose into it, but I can still smell it from yards away. Abraham Darby has a strong fruity delicious fragrance, but only if I have my nose close to it, and from a foot away I can't smell it at all, unless as a cut flower in enclosed space of the house.
