Vegetative Growth
3-6 monthsPlant develops multiple stems and produces new leaves regularly. Variegation becomes more pronounced as plant matures.
Provide consistent bright indirect light to maintain variegation. Feed with balanced liquid fertilizer every 2-3 weeks during growing season. Rotate plant weekly for even growth.
Stem Development
6-12 monthsPlant grows taller with more pronounced woody stem structure. Lower leaves may naturally drop as plant develops height.

Fun Facts
- 🌱 The name 'Dieffenbachia' honors Joseph Friedrich Wilhelm Dieffenbach, a 19th-century German botanist, while 'Reflector' refers to the silvery, light-reflective quality of the variegated leaves.
- 🌱 Dieffenbachia contains calcium oxalate crystals that cause a numbing sensation if ingested, hence its common nickname 'Dumb Cane'—a historical name referring to the temporary loss of speech if sap is consumed.
- 🌱 The variegation in Dieffenbachia Reflector is not stable; chimeric tissue creates the pattern, and new leaves may occasionally revert to solid green or white, making each plant uniquely variable over time.
