Its a wide wonderful world out there and one of the neatest things about growing plants is that there are always surprises. The group of plants known as Aroids is a very diverse group. But one of the coolest things about them is that sometimes, the exact same species of plant can look different...and its just a natural variation. Sometimes if the variation is so markedly different that there are several things going on at once (different leaf form + different petiole size/shape+ different venation etc) a species might be given the designation 'subspecies' (ssp.) of '________ form) fill in the black...large vs small, etc.

But one of the coolest plants that just has a lot of natural morphological variation is Epipremnum pinnatum. Its fairly common, can be found on many sale platforms. There is even a super pricey variegated form. But the plain green one is great too! Here are two of my about 100 plants...this plant is rampant spreader and pops up everywhere. The first photo shows a form that is not only pinnate, but also fenestrated, like an older Monstera

While this one is simply pinnate.

Variety is the spice of the aroid world!

They're beautiful, both of them! I can see how sometimes making an ID can be difficult with so many variations out there.

I love Epipremnum pinnatum! Mine aren't nearly as mature as yours but I also have two very different forms. The one on the left is the more common smooth form with quite thin leaves, the one on the right is a form with bullate, rounder, thicker and almost waxy leaves. Both of these are new leaves of about the same size.

And the full plants; under the growing conditions in my room the one on the right stays much more compact with smaller leaves.

I love that shiny one! I was recently talking to an aroid grower in Columbia who grows a lot from seed, he said he frequently gets plants that look totally different in some ways from the same batch of seed.

That is fascinating to me, but I shouldn't be surprised. Nature does some crazy things. I'm still working on pollinating Ags over here, been quite a waiting game but it's interesting to hear that aroids can produce different looking plants from the same batch of seed. I knew this about Hoya, but for some reason I didn't expect it as much from Aroids.

I love this post - what are the street names of your plants? Some of these are also known as cebu blue? And the juvenile vs the mature form?
