How to make cut flowers last long

If you’ve ever bought a bouquet of Alstroemeria, you’ve probably been amazed by how long these cut flowers last. While roses and other popular florist offerings wither after just several days, Alstroemeria have been known to thrive in a vase of water for three weeks!
That’s just part of the appeal of this plant, also known as Peruvian Lily or Lily of the Incas.

Alstroemeria flowers, which resemble clusters of miniature lilies, bloom in late spring and early summer in an array of colors – orange, pink, purple, rose, red, yellow and white – many of them with striped petals. Many hybrids and about 200 cultivars have been developed over the years, making them a florist’s staple for bouquets

here’s a fun article on test done to see what carrier is best to keep your cut flowers thriving in (from aspirin, sugar, to bleach, and listerine lol)

HOW TO HELP CUT FLOWERS LAST

Keeping cut flowers fresh for weddings is especially demanding; they have to look good through a couple of hours of photography, as well as the wedding and reception. The key is proper hydration,

  • Harvest flowers two days before the event, and choose blooms that are about three-quarters open. Do it early in the day while the air is still cool; plunge the stems immediately into a bucket of cool water.
  • Recut stem ends under water, then keep stems immersed in a bucket of water for 24 hours in a cool, shaded place. Use water alone or add a drop of bleach to keep it clean longer. If you’re working with hollow-stemmed flowers such as dahlias or mignonette, invert them one at a time, fill the stem with water, stop up the end with your finger, then plunge the stem upright back into the bucket.
  • Arrange flowers in a water-filled vase for maximum life. Or arrange them in floral foam, which provides more design control but sacrifices some vase life.
