Frequently asked
- Is lisianthus a rose?
- No, botanically unrelated. Lisianthus belongs to the gentian family. Visually, the double form strongly resembles a rose.
- How long does lisianthus last in a vase?
- With fresh A1 stems and clean water, lisianthus lasts 10 to 14 days. Because several buds per stem open in sequence, the bouquet stays lively throughout — new blooms open while older ones still hold.
- Is lisianthus toxic to cats and dogs?
- No. Lisianthus is listed as non-toxic to cats and dogs by the ASPCA. Nibbling larger amounts may cause mild stomach upset, but unlike lilies the plant is entirely safe.
