Two of my favorite types of flowers are lilacs and lilies of the valley. I love their scents, and the fact that they only bloom around here for a few short weeks in the spring makes it imperative to seek out and enjoy beautiful new blossoms at every opportunity. That's why we drive out to
Lilacia Park in Lombard every year and take pictures. My profile picture was taken there, as was this close-up:

Sometimes when we go to Madison (tomorrow's topic!) for WisCon, I'll buy a bunch of lily of the valley at the Farmer's Market and carry with me from panel to panel. It's a shame the flowers don't last very long once plucked. If we'd gotten married in the spring instead of fall, I would have included them in my bouquet.
Ironically, we don't have lilacs or lily of the valley in our yard, though perhaps this year might be the time to try introducing them.
Another "l" flower with a wonderful scent is lavender. I am actually growing them from seed for my garden; I started them a few weeks ago. I do have seedlings at this stage, but they wouldn't make an impressive picture.
Any other flower fanatics out there?
