Q.how long does anthurium take from seed to flowering
I plan to cultivate Anthuriums and would like to find out how long it takes for them to flower and get to about 30 cm? Basically, I would like to know the period from planting (seeds) to flowering/selling.

Commercially grown Anthurium are generally propagated from cuttings and grafts.
It is possible to grow from seeds but they do need greenhouse production or be grown in tropical zones.
Grown from seed, it will take 2 to 3 years for flowers to form.
