In order to color Anthurium flowers blue, a European business created a patented procedure in 2011 of injecting blue dye into the roots as the flower buds are growing. It’s a difficult procedure, but the results are fantastic. Princess Alexia Blue is a blue anthurium from the Dutch business Rijnplant. They also offer a yellow one called Princess Alexia Yellow. “The plant is as natural as possible; the color is absorbed by the leaves via root pressure.”
Care tips:
- Like to be warm, with a minimum temperature of 60°F in winter.
- Easily propagated by plant division.
- Bright light but no direct sun.
- Yellow leaves indicate over watering – Brown leaf tips indicate too little water.
- High humidity.
Fertilizer
Throughout the growing seasons, phosphorus-rich fertilizer should be gently fed to plants on a regular basis to promote growth and color.
