Aroids

Aroids belong to the Araceae family, which includes climbing forest plants, ground-growing herbs and species that root on trees. Some form roots along their stems, while others grow from thick underground structures.

Their flowers are arranged on a fleshy spike called a spadix, often accompanied by a leaf-like spathe. These structures can be inconspicuous on foliage plants and brightly coloured in flowering aroids such as Anthurium.

Monstera deliciosa develops broad, divided foliage on climbing stems. Philodendron gloriosum carries velvety heart-shaped leaves along a creeping stem, and Anthurium crystallinum has striking pale veins. Aglaonema adds colourful upright clumps, while Alocasia includes compact, textured varieties and tall elephant-ear forms.

Growth habit is particularly useful when choosing an aroid. A climbing vine can extend up a pole or plank, a crawling stem needs room across the growing medium, and a mature leafy crown may spread beyond its nursery pot. The actual variety determines its eventual size and leaf shape.

Many tropical aroids grow well in indirect daylight and an open potting mix. Their moisture and light requirements vary by species, so the individual plant's care information matters. Many familiar aroids contain calcium oxalate crystals that irritate the mouth if their foliage is chewed.
