Pessimists. Such a negative lot. Always complaining about something. If it’s not “romance is gone,” then it’s “chivalry is dead.” Paul Robertson is a man determined to change all that. A hopeless romantic and expert florist, he designs sweet, simple arrangements void of baby’s breath and filler greens. His special deliveries contain stunning monochromatic bouquets of peonies, French tulips, and dahlias. He’ll deliver weekly, decorate for a party, or do an entire wedding. And because he buys from local growers and arranges them in his SoMa digs, his garden-fresh picks start at just $50. Which should keep both your mood and your bank balance up. Now just try being pessimistic about that. Paul Robertson (415-412-3374 or prfloraldesign.com).
