Funny thing about theme parties: You outgrow them sometime around adolescence (ever tried to get a 15-year-old into a costume?), only to grow right back into them in adulthood.

So you’re probably just about the right age to appreciate the latest trend in high-concept entertaining: flower-arranging parties. Jasmine Blue, a flower shop in Sherman Oaks, is in the business of helping you and your friends unleash your inner flower children, so to speak.

Here’s how it works: You bring the guests (they recommend five to ten), food, and music; Jasmine Blue provides the organic leaves, fresh mint, moss, exotic flowers, and the vessels in which to create your masterpieces. The best part? Guests get to bring home more than just a hangover and some twit’s business card. In addition to a lovely arrangement, they take with them a renewed appreciation for nature’s loveliness.

Think of it as a very grown-up event … with a dash of childlike wonderment.
