Botanical Name: Ornithogalum umbellatum (or-ni-THOG-a-lum um-bel-LA-tum)
Decorative Life: Up to 2 weeks in water alone.
Post Harvest Care:
  • Recut stems under water and place into a fresh flower food solution or plain tap water containing bleach (6-8 drops per quart) as fresh flower foods are not necessary, buds continue to open in water alone.
  • Flower stem bending when placed horizontal (geotropism) is a problem with all members of this genus. Applying calcium chelators such as EDTA and/or using one of the anti-ethylene action products (MCP of STS) can reduce this bending. To the contrary, ethylene synthesis inhibitors such as AOA or AVG had no effect on bending.
