What is the difference between calla lily and Alocasia macrorrhizos?

I. Calla lily

It belongs to the Araceae family and likes soil rich in nutritious humus. It is a herbaceous plant that can survive for many years and can grow to a height of 70-100 cm. Its stem is very plump and fleshy. The leaves are very emerald green, arrow-shaped, very large, and look very beautiful when spread out. The leaf stalks are very thick and large, and the flowers are very large and pure white.

II. Alocasia macrorrhizos

It belongs to the genus Alocasia in the Araceae family. The stem is very thick and sturdy and can grow up to three meters tall. The leaves cluster at the top of the stem. It grows in the south of our country and likes warm, well-watered, and cool areas. The suitable temperature is 20 to 25 degrees. It is relatively large in size and needs to be planted in a very large pot or barrel. It is suitable for placement in halls and looks very spectacular.

III. Differences

1. Actually, the simplest way to distinguish them is to add more water to the potting soil. If after a while water droplets drip down along the edges of the leaves, then it is the latter; if there is no dripping, then it is the former.

2. In addition, we can also distinguish them by their appearance. The former's roots are bulbous, its rhizome is very plump, its leaf stalks are very long, and its leaf shape is like an inverted heart. The latter's leaf stalks are relatively thicker and fleshier. The former's flowers are very similar to those of the peace lily; the center of the flower is an inflorescence made up of many small flowers, and its shape is very much like an inverted horseshoe, while the latter's flower looks like Guanyin draped in a layer of white gauze.
