Lilacs don't really grow well in Southern California -- at least not on the coast (I assume they need a hard freeze or something) -- so they're somewhat of a rarity. However, I've really loved them ever since I was a child, for some reason. I think it's the scent.
In any case, they appear at the shops and markets here for about two or three weeks sometime each spring, and even though I usually haven't had a line item for flowers in the budget lately, I decided this bunch was worth every penny of the $8.99.
Nothing says spring to me like this.
