Mine are all called Eric. It's much easier to remember.

I don't but I do give my ugly/sick plants nicknames like "Dying plant" or "One leaf". The nickname usually sticks after the plant is healthy again. Dying plant is now a 2 meter high tomato plant full of blossom and Oneleaf has 3 leaves now.

Only a few... now I feel bad for all the unnamed

My big alocasia zebrina is Stampy, and my little amazonicas are Thing 1 and Thing 2

Jack is my hatiora salicornioides, and Sally is the tradescantia that lives next to him

My beautiful old mess of coppertone sedum is Grampus

The reaching tradescantia under my office window is Medusa

Gollum jade is named Coral

And my peperomia graveolens is Ruby

Some are not overly creative, lol

I do! I’ve got Elphaba, Hawthorne, Sonic, and Phil among others lol

I used to, now I have so many that's it's enough work to remember the species names.

I have 12, each with its own name haha. It's usually just a play on their species name though, so it is easier to remember initially :)

Sometimes and sometimes not. Depends on how much shit they give me… the harder ones to take care of usually get a name

Some do, some don't. My Lithops was named something ridiculous like Sir Buttington III.... no wonder it decided to die on me
