There's a few plants that have these kind of "widnows" on top of their leaves (google "leaf window"). They are adapted to very harsh, hot climates. The windows allow them to remain mostly buried in the soil and keep the photosynthesizing part of the leaf protected from the harsh conditions while still being able to collect light.

Again, looking very much like their namesake.

Is this how they harvest hops?

Bonsai Tree's final form.

Perfect for Medusa!

Curly Q's.

They look like brains but also like candy and now I feel a little like a zombie...

That's just one type of echeveria, they come in many beautiful colours

Lots of love.

Love the colours on this one.

I honestly thought this was a beaded pincushion upon first glance. I had to Google it, and supposedly it is called "euphorbia obesa" and it does indeed look like the photo above. Pretty amazing!

Cake icing.

Now those are some huge potato crisps/chips

Looks like a flower.;.A very hairy one, though!

Fun fact: A group of dolphins is called a pod. Now I know why!

Like waves ... mesmerizing.

Just wanted to mention that the top part is a planter and the bottom is the plant itself. Still cool tho, since they grow upside-down.

This is not a succulent at all. It’s an air plant glued to a seashell.

Those are air plants in a type of sea shells for display that is not a part of those plants.

this is an air plant not a succulent

They look like the kind of monsters that would attack you in a humid cave, or something like this.

This looks like a jellyfish

I just love this idea to hang them upside down. Awesome😅🤣😁

Not a succulent but an air plant!

An Air plant, majic. Really cool

They look like jellyfish in this picture.

LOVE.THIS.

Triffids!

jellyfish succulent

Look like sea-urchin shells!

Now this one is an epiphyte, it's not a succulent (Tillandsia bulbosa)

Still really cool to grow upside down, the planter just adds to the plant making it look unique

I have one, I thought it was called an "air plant". don't plant in dirt.

Pretty neat

Unique.

looks like War of the Worlds...

War of the Worlds!

Look like alien life forms!

Those are air plants. Tillandsia C. Medusae, to be specific. I have three.

Not actually a succulent, a member of the bromeliad family.

Dr. Seuss?

Why is this not called a Lovecraft succulent???

Tillandsia Bulbosa , Air Plant

Look like UFO's..love these.

The 'planters look like sea urchin shells.

Now, this one is truly bizarre.

The fronds look like they're waving about in the air.
