Plant identity

Could anyone please identify this plant, it's got to this size from being taken all the way to the ground in less than a year.

Kerria japonica

 

Fantastic thank you, don't suppose you would know if it's safe to trim it back now or should I wait till after it flowers?

If you prune it now you are in effect removing any flowers that would open next year.
The time to do it is after it has flowered.
Quote from RHS..."Pruning: Remove flowered shoots back to vigorous side shoots. Cut back one in three stems to ground level each year."

I don't cut mine back, but I'm fairly certain it flowers on last year's stems, the only 'pruning' I do is cutting stems for cut flowers whilst blooming.

 

Never knew they would grow at the Equator

 

Definitely leave it now as it will be forming flowers now. Mine usually starts towards the end of January although you can get them intermittently throughout the year.

 

Just my opinion but I would remove it as I've found K.japonica to be somewhat a invasive shrub that spreads by suckers. I thought that I could control it but the more I cut it the more it seemed to sucker.
