Blue phalaenopsis were on the paint drip
An azure blue orchid on the store shelf is mostly the result of intensive pre-treatment. A Dutch breeder managed the stroke of genius to turn white Phalaenopsis orchids into a blue wonder of flowers. Since the resourceful gardener had the technology patented, the exact procedure remains his secret for the time being.

The public has been informed that the butterfly orchid is connected to a drip via an infusion needle, through which the blue color gets into its ducts. Of course, the blue magic only lasts a heyday. If the Phalaenopsis sheds the colored flowers, the next buds unfold in innocent white.
Vanda Royal Blue - Blue flowers with white flecks
Various hybrids have emerged from the demanding Vanda coerulea, which - without any color drip - produce blue flowers. Anyone who is willing to accept small white speckles in a deep blue can look forward to the blaze of color at any time of bloom. Of course, the standard of care for a Vanda orchid is somewhat higher than for a frugal Phalaenopsis orchid. You can only make the blue Vanda bloom under the following conditions:
- In a continuously bright location, without blazing sun at noon and early afternoon
- Warm temperatures between 18 and 22 degrees in winter and 25 to 30 degrees in summer
- High humidity of ideal 80 percent, at least 60 percent
Since a Vanda thrives without a substrate, it is mainly cultivated hanging freely or in a lattice basket. To ensure the supply of moisture, soak the aerial roots in soft, room-temperature water for 30 minutes every few days. In the summer, add a liquid orchid fertilizer to the diving water every 2 weeks.
The news reached us from Japan that the first real blue butterfly orchid had been successfully grown there. Thanks to intensive genetic manipulation, the hybrid produces blue flowers with a diameter of up to 5 cm on 30 cm long flower stalks. However, it will be several years before we can buy this orchid in the garden center.
