A Propagating Master
There is a reason why they call this houseplant the Friendship Plant. Its because it's the gift that keeps on giving. It's a self-propagating master. I mean the reason why this plant became so widespread in Europe and America, is because of that reason.
This plant is probably one of the easiest plants to propagate, because..well..they do it on their own! Pilea shoot out pups or new plant babies from the mother plant or stem. You can easily snip them and place them in their own pot to grow roots, or leave them there to grow and thrive (aesthetically, this is up to you).
Quick Tip: These plant buddies make wonderful gifts to friends and family. Since this plant grows so fast, you will always have new plant babies. I would honestly recommend giving away a lot the pups or your own plant jungle might just end up being all Pilea (nothing wrong with that, but I think you catch my drift)!
