For monochromatic arrangements that use the highest-quality blooms, including Dutch hydrangeas, Japanese sweet peas, gloriosa lilies and Italian anemones, look no further than this Gowanus outpost. Also notable is the lack of filler flowers: You won’t find baby’s breath, ferns or gladioli here. If you’re in the market for a last-minute bouquet, Brazilian-born owner Mauro Gomes can bundle an arrangement containing lilacs, tulips, calla lilies and other nonrose flowers, as late as Valentine’s Day at noon. Arrangements start at $150, which is also the minimum for deliveries.
