Flower of ther Month: Bouvardia
SAF - Flower and Plant Care
Botanical Name:
Bouvardia spp.
Ethylene Sensitivity:
Accelerated wilting and abscission result from exposure of Bouvardia flowers to ethylene.
Pretreatments
Because of their ethylene sensitivity, Bouvardia flowers should be pretreated with 1-MCP or STS. Research has shown STS to be the superior pre-treatment because it protects not only the open flowers but also the developing buds from the effects of ethylene.
Storage Conditions
Although previous recommendations have been to store Bouvardia at 45-50ºF, this species is not chilling sensitive, and therefore should be stored, like most temperate cut flowers, at 33-35ºF.
Vase Solution Requirements
Fresh flower foods prevent bacterial contamination of the stems, which is the cause of early wilting in Bouvardia, and provide sugar which improves bud opening and color of the flowers in this species.
Consumer Life
7–14 days
Purchasing Hints
Purchase when one or two flowers are open on each stem. Avoid flowers that have yellowed foliage, or are showing signs of wilting. If the flowers have been pretreated to prevent the effects of ethylene, there should be little shattering when the flower bunch is shaken.
Additional Information
Bouvardia exhibits leaf yellowing and is wilt sensitive. In some markets a special fresh flower food formulation is sold which can reduce leaf yellowing. Recut stems underwater and use good sanitation procedures to reduce the chances of wilted flowers. Postharvest performance differs greatly among the many cultivars marketed.
Bouvardia flowers are a relatively recent addition to the florist’s palette. Their bright salmon, red, and white color range and interesting flower form offer interesting design possibilities. The genus is named after Charles Bouvard, 1572-1658, who was physician to Louis XIII and superintendent of the Royal Garden in Paris
