Monstera Albo (Monstera deliciosa 'Albo-Variegata') and Thai Constellation (Monstera deliciosa 'Thai Constellation') are two highly sought-after variegated cultivars of the Monstera deliciosa species. Both are prized for their striking foliage, but they exhibit distinct differences in appearance, growth habits, and care requirements. Understanding these differences is essential for plant enthusiasts looking to cultivate either variety successfully.
Monstera Albo: This cultivar is known for its dramatic white or cream variegation, which appears in large, irregular patches or sectors on the leaves. The variegation is unstable, meaning it can revert to green if not properly maintained. Leaves may also exhibit half-moon patterns, where one side is entirely white.
Thai Constellation: In contrast, Thai Constellation displays a more stable variegation pattern, with creamy-yellow or light green speckles and splashes resembling a starry sky. The variegation is distributed more evenly across the leaf, and the plant is less prone to reverting to solid green.
Monstera Albo: Due to its unstable variegation, Monstera Albo requires careful pruning to maintain its white patches. All-green shoots should be removed promptly to prevent reversion. Growth can be slower compared to non-variegated Monsteras, as the white portions lack chlorophyll and cannot photosynthesize efficiently.
Thai Constellation: This cultivar grows more consistently and is less likely to revert. The variegation is genetically stable, making it easier to maintain. Thai Constellation tends to grow faster than Monstera Albo, as its variegation still allows for sufficient chlorophyll production.
Monstera Albo: Bright, indirect light is crucial to sustain its variegation. Too little light can cause reversion, while direct sunlight may scorch the white portions. A north or east-facing window with filtered light is ideal.
Thai Constellation: This variety also thrives in bright, indirect light but is more tolerant of lower light conditions due to its stable variegation. However, insufficient light may reduce the intensity of the variegation over time.
Both Varieties: Monsteras prefer consistently moist but well-draining soil. Overwatering can lead to root rot, while underwatering may cause leaf browning. High humidity (60-80%) is beneficial for both cultivars, but Thai Constellation is slightly more adaptable to average household humidity levels.
Both Varieties: A well-aerated potting mix with perlite, orchid bark, and peat moss is recommended. Fertilize monthly during the growing season with a balanced, diluted fertilizer. Monstera Albo may require slightly less fertilizer due to its slower growth rate.
Monstera Albo: Propagation through stem cuttings is possible, but the variegation may not carry over reliably. Cuttings must include a node with visible variegation to increase the chances of producing variegated offspring.
Thai Constellation: Propagation is more straightforward, as the variegation is stable. Tissue culture is commonly used for mass production, ensuring consistent variegation in new plants.
Monstera Albo: Due to its unstable variegation and high demand, Monstera Albo is often more expensive and harder to find. Prices can vary significantly based on the level of variegation.
Thai Constellation: While still pricey, Thai Constellation is generally more affordable and widely available, especially as tissue-cultured plants become more common in the market.
Monstera Albo: Prone to browning on white variegation due to sunburn or low humidity. Maintain proper light and humidity levels to prevent this issue.
Thai Constellation: Less prone to browning but may develop yellow leaves if overwatered. Ensure proper drainage and avoid waterlogged soil.
