Color Variation in Drosera adelae: Red vs Green Seedlings

A grower notices some D. adelae plantlets are deep red while others are green, despite identical conditions, and wants all red plants.

Natural Variation Explained

• Age differences: Older plantlets develop more red pigmentation
• Micro-light variation: Slight shading differences within a pot
• Genetic variability: D. adelae shows wide phenotypic plasticity
• Not a problem: Both colors indicate healthy plants

Encouraging Red Coloration

• Maximize light intensity (full sun or strong artificial)
• Ensure even light distribution across pot
• Accept that some individuals stay greener
• Red color = anthocyanin production under high light

Realistic Expectations

Uniform intense red across all plantlets is unlikely in a clump. Focus on overall health—dewy, actively growing leaves—rather than uniform color.
