Aglaonema bidadari...Very Beautiful specimens!
Care: A bright position would be ideal, but he will also tolerate low light. Keep the soil moist. When I water my plants I always check the soil first by sticking my finger about 3 cm down to check if it still feels damp if so I hold off until next time.
Size: Pot Diameter 12cm - Total height is approximately 25-30cm
Toxicity: Considered poisonous. Keep out of reach children and animals.
Difficulty: Easy - Just don't over-water :)
Air-purifying: Yes the Aglaonema family are great air purifiers.
Feeding: General, the majority of houseplants should be fed every 2nd watering during the growing season (Spring and Summer), for me, it's about which every 14 days. In autumn and winter, I feed less, as indoor plants will require fewer nutrients.
