Tropical ground cover

Please I need some suggestion with some fast growing tropical looking ground cover for this summer .
I`ve tried corsican mint , but very slow grower , pennyroyal mint doing fine but not the look i want , tradescantia turned to be really invasive , but impressive adapting plant any suggestion?

 

Lotus berthelotii maybe...............

 

here are a few:

not sure if it is the sort of look you are after though

black mondo grass could be an option .... hardy, evergreen, grows in full sun and deep shade .... pricey though and a bit slow growing

 

Lotus berthelotii look more like a must have for basket , btw is it a full frost hardy?
Dim , black mondo is great but I have to admit that is one of the most slow grow plants I`ve got , any other idea?
this is what I`m using at the moment , but will not cover the dry side and realise that corsican mint is not really frost hardy (so far ).
Corsican mint


and pennyroyal mint.

 

What look are you after Sal? if you want the jungle look, then easy hardy plants to cover the ground are ferns, hostas, heuceras all can be made to give an exotic impression and also are fairly inexpensive. Then you have things like mind your own business - soleirolia soleirolii easy and hardy but needs water to look its best.

 

soleirolia soleirolii!!!
that`s almost the look I`m after , is it the same one is growing around your small pond?don`t really want to use fern , hostas or heuceras as ground cover i want something around them something that grow fast .

 

Yes that's the one, you can get them in small pots which divide easily and as long as kept watered they grow fast.

 

will be hard to keep it watered with the hosepipe ban , but the plant look good , actually they are sold even in different shade of green , nice one Gaz .

 

Maybe a form of Oxalis (not the rampant kind), or some ground cover type of Lysimachia such as L. lysii? Lysimachia plants are generally fairly hardy but not sure if they are evergreen.
