Ce qu'on demande souvent

Can I grow this in my garden?

No, it is impossible to cultivate outside of its highly specific wild ecosystem.

Why is it so rare?

It requires a very specific host shrub and soil fungus to survive.

D'où vient le nom

The name Rhizanthella comes from the Greek words for root and flower, describing its underground habit.

Bon à savoir

• It lacks chlorophyll entirely.
• It relies on a specific fungus to bridge nutrients from a host shrub.
• The flowers are pollinated by tiny gnats and beetles.
• It was only discovered by accident by a farmer plowing a field.
