The Thai Constellation (Monstera deliciosa 'Thai Constellation') is a stunning, variegated variety of the well-known Monstera deliciosa. It is famous for its striking, irregular white or cream-colored marbling on dark green, fenestrated (split) leaves. This plant has become a highly sought-after houseplant due to its unique appearance and rarity in the plant market. However, because of its beauty, the Thai Constellation can also be a bit more challenging to care for compared to the standard Monstera deliciosa.

Sunlight:

The Thai Constellation thrives in bright, indirect light, which helps it maintain its stunning variegation. The white and cream areas of the leaves need plenty of light to stay vibrant and not revert to green. If the plant doesn't get enough light, the variegation can diminish over time, and the plant may develop more green foliage with fewer creamy spots.

Avoid Direct Sunlight: While it needs a lot of light, direct sunlight can scorch the leaves, especially the variegated areas. Prolonged exposure to direct sunlight may also cause the plant to lose its variegation, leading to a more green appearance. Use sheer curtains if placing it near a window that receives direct sun.

Water:

Moderate Watering: Like other Monsteras, the Thai Constellation prefers to dry out a bit between waterings. Water it when the top 1–2 inches of soil are dry. During the growing season (spring and summer), it may need water more frequently, but in the winter, its water requirements decrease.

Avoid Overwatering: The Thai Constellation is susceptible to root rot, so it’s important not to let the soil stay waterlogged. Make sure the pot has proper drainage and that the water drains freely.

Temperature:

Warm Temperatures: The ideal temperature range for the Thai Constellation is 60°F to 85°F (16°C to 29°C). It is sensitive to cold temperatures and should be kept away from drafts, cold windows, and air conditioning vents.

Avoid Cold: Temperatures below 50°F (10°C) should be avoided, as the plant may experience stunted growth or damage.
