Unfortunately, I haven't found an orange with a massive smell.
Mardi Gras smells a bit, but the others really don't have a scent to write home about. And, if *I* can grow roses, ANYONE can grow 'em! Seriously! They're the easiest things ever! If you're wanting fragrant, try Memorial Day, Blue Girl (I'm prejudiced), Intrigue, Heirloom, Dolly Parton, Firefighter,... uh... thinking... hmm. drawing a blank here. ugh. Mr. Lincoln, Enchanted Evening, Medallion, Pure Perfume, Lagerfeld, Oklahoma, Barbara Streisand, .. can't remember if my Sunsprite has a scent.
gah, that's the only ones I can think of that you can smell strongly that I have (well, technically, I gave my Firefighter to my M-I-L for M'day). I have Fragrant Plum, but it hasn't bloomed for me yet (it's just a 1gal potted).
uh..... let's see: front row: Acadia Sunrise, Hot Tamale
Second row: Ebb Tide, Arizona, Lagerfeld, Strike it Rich
Third Row: Arlene Francis, Purple Heart, Europeana
Fourth Row: New Year, Purple Passion, Stainless Steel
Fifth Row: Tuscan Sun, Dolly Parton, Joseph's Coat, Paradise
6th Row: Montezuma, Voluptuous, California Dreamin'
7th Row: Cinco de Mayo, Tequila Sunset, Citrus Splash, Heirloom
8th Row: Charisma, Intrigue, Picante, Intrigue, Charisma,
9th Row: Oranges & Lemons, Mardi Gras, JFK, George Burns, Paradise Found, Austrian Copper
10th Row: Moonstone, Modern Tempi, Orange Velvet
that's just in the front yard. And I have a tiny front yard. I know there's at least 3-6 more that I've forgotten their names. I can see the sticks, but I can't place a name on them.
Thank goodness for labels.
Somewhere also in my yard I have a Scentimental, but I have no idea where I put it as I didn't label it and it hasn't greened up enough to poke through the mulch yet.
