This is one of my two A.gigas grown from seed distributed by J.Symon in the end of 1994 after his trip to Sumatra. The vigor of the plants is rather uneven; the smaller one (not shown here) is about the size of the smaller of the two larger leaves. Ever since the seed germination, there was no pronounced dormancy. Just like A.titanum and A.prainii, A.gigas keeps going and going.
A. gigas seems to be quite resistant to maltreatment. It has survived several nights with temepratures dropping to low 40s F, without losing the leaves. Later, it survived being flattened by a bicycle which fell on it, bending the main petiole so it became nearly parallel to the soil surface. Actually, I suspect that the entire tuber has rotated with the stem, perhaps severing some roots. After two weeks with a support for the petiole, the plant is standing up on its own as if nothing happened. The third stem got squished, though.
This species is very susceptible to aphid and spider mite infestations. The damage occurs very quickly. It also dislikes low humidity, with similar symptoms as A.odoratus: the leaflets curl down severely.
