16 Planted rosaceous shrub around Ulster? Talent once needed (8)

The letters I have look very odd, so am wondering if I've gone wrong elsewhere.

Thank you

Either Ingenium or ingonium ?

I am also stuck on this one
Is 22 Grillone

[Toorak]

Ingenium I think - geum is a rosaceous plant

[JJ109]

Thanks, jj and Toorak.

JJ109 re 22 - kind of, but the first letter is the N.

My last clue to get, though I've some slotting in still to do...

Body left by us returned stirring, formerly prone (8) My current letters are not certain, but involve IVE.

[Spoffy]

A six-letter word for a body, having US removed ('left by us') and then being reversed ('returned'), followed by a four-letter word for 'stirring', which involves your three letters. The whole is an archaic word meaning 'prone'.

Thanks, Spoffy.
