This is your official notice that Mother’s Day is in two weeks, and unless you want to be rushing deli flowers over on your bike, you better order a bouquet delivery today. If you want to splurge, Flowers of the World (you’ve seen their work at the Peninsula) will customize an arrangement with blooms like this rare Phalaenopsis orchid, above, for $450. For those not inclined to spend like a Master of the Universe, enchanting Spruce has a sweet-and-simple six-rose cube in for $50. Call it Mom-inalism.
