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!
