Hyacinths are a perennial that is native to Lebanon, and they smell good, too.
Hyacinthus orientalis (
common hyacinth,
garden hyacinth or

Oh, lucky you! It says here :
http://www.gardenguides.com/120551-flowers-lebanon.html . . that your winters are mild enough you can have flowers bloom year-round! There's a list of flowers for all seasons. It doesn't say whether they're perennial or not, so you'll have to do a bit of research.
At this website:
http://www.theflowerexpert.com/cont...rs/national-native-popular-flowers-of-lebanon . . I got this:
QUOTE = "Some of the native flowers of Lebanon include,
Eunomia oppositifolia, Origanum libanoticum and
Hyacinth (lily).
The popular flowers of the country grown here are, Opium poppy, Blue Stars, Begonia, Zinia, Vinca, Camelia, Poppies, Dahlia, Oeillet De Chine, Jasmine, Almond Flowers, Mirabilis Jalapa , Alyssum Montanum, Tropaeolum, carnations, Latana Camara, snow white, Cactus, cortanica Mirabilis jalapa, Gerbera, Arum, Red Eye, Gladioulus, Orange Flowers, Iris and wild flowers.
Roses, Lilium, Hortansia, Sun Flowers, Red Bell, Gerbera, Arum, Red Eye and Gladioulus = UNQUOTE.
Again, I don't know if everything is perennial in that list, but I don't know what colors you like, either, so you'll have to look them up. At least it gives you a place to start.
Hope that helps!
