I’ve had this plant for a few years. It has never flowered. The person who gave it to me called it a pickle plant.

Color change since I got it about 70 days ago!

I've been starting seeds every few weeks the past 2 years and now have over 1000 seedlings. I told myself I wasn't going to start more this year but hear I am trying to sell random shit and hustle aztekium ritteri seeds because in my head I can justify a super slow cactus seeds that will be in a pot that won't take up but only 2.7"×2.7".

Anyway. Happy growing!!!

I've never seen a cactus with this.

From order of appearance:
Strombocactus disciformis f. cristata
Espotoa Nana f. cristata
Gymnocalycium ochoterenae sp. vatteri 'single spine'

It has bloomed once in the winter with tiny white flowers and was neglected for a while after. Now it is a bit taller and lopsided so it's hard to identify. What is this?

This was labelled as dragonfruit but Seek says dogtail cactus. What is this?

I'm not sure if the shriveled flower is identifiable but it was a beautiful red flower. I have seen this thing flower twice. It was unlabeled at my local nursery, so I'm curious what it is and if it needs to be repotted.
