Which tree species root over rock?

[leatherback]

Earlier in the year I got a case of Seiryu rocks to start root over rock compositions. Considering the number of rocks I have I am wondering whether there are species that would make great root over rock, but are not seen that often.

Right now, I am mainly contemplating trident maple, Ittoigawa juniper and corkbark elms, as I have seedlings/cuttings standing around. But.. Who knows. Maybe I am overlooking the obvious. So here goes, I need some inspiration and would love to see your root over rocks, and hear suggestions for species to use!

Chinese Elms go well. Big Ficus. Piracanthas. Some Boxwood.

Your local maple.

Field maple? Or sycamore maple?

No way I am growing Mugo from seed. I only have 60 more years of life left!

That plenty!

Those pieces are problem too small for the sycamore maple?
But they been saying feild maple is a fast grower too.
I really think an excellent root priming basket and done soil does a great job of freezing roots, so I'd definitely have it in a basket between the point where the roots grip and "Refinement", to keep the rock from getting swallowed, that way you can use a bit faster of a grower.

Then even, constructing a basket the same shape as your show pot, so it can be easily moved, can keep it from swallowing the rock even longer.

A little sad to see politics everywhere

I’m excited to see what you end up with - I hope you continue to update!
But also my vote is for Ficus benjamina.

Hmm. Is it political? Or is it referring to the fact that most hot water knobs are on the left, therefore a lefty would gravitate towards turning the hot instead of the cold.....Either way in my short time on the forum Sorce has proven to have an OPEN mind, so in my book...if its political, it is welcome.

 

[Wires_Guy_wires]

Prunus cerasifiera or whatever that red/purple leaved prunus is called.
If you're more into crevases extravaganza, consider a cork oak.

Not gonna happen at my latitude!

cork oak

I happen to have 2 seedlings of cork oak. Might be an idea!
Are they winter hardy though?

It’s true but it’s sorce. He’s probably going for reactions. Lol

This actually screams @sorce!

They go up to the north of France native. A little care and you probably could.

So they take -20c?

 

[Dav4]

JBP look great on a rock, so I'd imagine Scots pine would look good too.

That I’m not sure of lol. Let me translate to °F and see what I can find.
