Bottle brush? if it is its botanical name is Callistemon. as to which one - no idea.

Thanks Seaburngirl, the flowers do remind me of bottle brushes. Will have a search now to see if I can pin point it.

Possibly callistemon linearis

My first thought was Bottlebrush, too.

It looks like Lemon Bottlebrush (Callistemon citrinus), to me.

Thanks for your comments, sorry so long answering,but spent a large part of 2019/ 2020 in hospital nearly didnt make it out from last four week stay. Was on a ward where we had isolation rooms and for a while my visitors had to wear ppe,my heart goes out to those now in hospital due to corona virus, very frightening for them and relatives.
