First time flowerer for me...Pediocactus knowltonii, grafted on Pereskiopsis....Haven't seen plants here in Oz, anyone else growing it ?

Thats a beauty I have a nice crest growing on Hylocereus. I will get a photo for ya.

That's really nice Navajoa. The body kind of reminds me of reminds me of a Mamm. I really like it.
Is this one a particularly slow grower?

Here we go my Knowltonii Crest>

Wow Hellonasty, that's certainly pumped it up ! Looks totally different... thanks for showing us it...

Kanje, they're not what I'd call very slow, but they can be quite touchy on their own roots and the seed can be hard to germinate. I have plants on their own roots that are about 4 years old that are budding up, so probably the same speed as a lot of other stuff...
Knowltonii is probably the "easiest" and one of the best of the Pedio's though, should you ever want to give it a go...

thats a beauty navajoa! and that crest is awesome nasty!
