Care Tips

Water Regularly: 

Amorphophallus Muelleri loves water during its active growing period. The plant can be kept in highly permeable soil with organic matter. Keep them evenly hydrated while they are growing, but allow them to dry out completely while they are dormant. If they are too wet while they are dormant they can rot. Water and fertilize regularly for best results. It is important to supply them with phosphorus. Phosphorus is what allows them to grow a larger tuber. Since they grow a new tuber each year, this is largely what determines the size of the plant in the following year.

Soil in Active Growth: 

Provide a well-draining chunky soil and keep it constantly slightly moist. It goes dormant in Winter or when it is cold. In this case, the tubers can be stored in a paper bag while in its resting period. 

*The goal for Amorphophallus Muelleri Care is to keep these tubers hydrated without being consistently immersed in a soggy moist medium. 


This species prefers light sun, while avoiding direct hot afternoon sun. It also likes a humid environment. In addition, it prefers a temperature above 20 degrees celsius (68 degrees fahrenheit).  


When a soft spot is detected, carve out the soft infected areas up until you see only fresh flesh of the corm. Then brush over Sulfur Fungicide Powder and leave in a sunny area so the wound(s) can dry and scarify quickly. Be sure to keep away from potential pest infestations.

If you find that some spots are taking longer to dry and have any concerns whether it may still be compromised, carve back that area as quickly as possible and repeat the treatment process in that area. Once the wounded areas are completely dry, the tuber can be returned to the soil.

Amorphophallus Muelleri 

Amorphophallus Muelleri if found in Java. It grows one leaf from it’s tuber annually. This leaf can reach up to 4′ tall and 3′ in diameter. Like Amorphophallus bulbifer, the leaves on Amorphophallus Muelleri grow bulbils from the leaf axis. Amorphophallus Muelleri reproduces asexually via bulbils that grow right in the middle of the top of the leaf. The larger the leaf, the larger the bulbil produced. An ideal time to harvest the bulbil off the leaf is when it has finished its growing cycle and drops its leaf.

The leaf is grown using carbohydrates stored in the tuber. The tuber is completely used up in this process. During the growing season, a new tuber begins to form below the plant. Meanwhile it stores resources obtained by the leaf and roots for use in growing the leaf or inflorescence in the following Spring. 


Amorphophallus Muelleri is apomictic. This allows the inflorescence the capacity to produce viable seeds without being pollinated. The seeds produced via apomixis are clones of the mother plant. When in bloom, do not interrupt the cycle. This may allow the inflorescence to grow fruit and seeds from its side. The seeds can be harvested in the spring and planted immediately.  Like other aroids, the flowers are not capable of pollinating themselves. Therefore, new plants will be clones of the mother plant. Otherwise, it would require 2 blooms to cross pollinate. 

From seed or bulbil to a bloomng size plant, it takes approximately five to six years. However, once it reaches blooming size they bloom approximately every two years with proper care.
The petiole of the leaf is mottled with attractive patterns of light green splotches. The purple spathe is 7″-8″ in diameter and has white polka dots. The spadix is pointy with a creamy white color.
