Grevillea banksii
Not being a hybrid I though they would last longer than eight and a half years
Does anyone know.
I have searched on line and cannot find a answer and as I have three in the same area, and if they are going to only last around that time I think we will dig them out.
Cannot have any more of them falling on other precious plants..

| I have grown many Grevillea and have 2 living at present that are 3 years old and doing well but all the others Ive grown never lived past 6 years , but that may only be the case in the tropics, they are not a long lived plant and are used as a filler till slower trees grow.Pitta. |

Hi Pitta and Thanks... Yes I am surprised that they lasted that long they were the first plants I planted after we bought the block and cleaned it up, I thought I would plant some toughies as when we first started building the house and waiting to get the town water connected we had to bring water over in containers every day for the many cuppa's and washing hands while we were building so did not have the room for extra water for plants only did that once a week, so only planted Grevillea and Syzygium sadly those eight died as did the Grevillea ground covers
In that case we will dig the other two out as well...

They don't live long but their life can be extended by regular pruning by a few years. Ours would be about 9yrs old now and no sign of dying yet. Every year we cut them back by at least half (can't reach any higher - they are on top of the bank) and they come back better than ever. It isn't a light pruning - often use the chainsaw  It probably goes against all the pruning grevillea rules but it isn't hurting them.
Yours was probably weakened by the rain and the strong winds today wouldn't help, they don't have deep roots. The others could last for another few years yet.
I just found a pic of one of ours dated Nov 07 that was pruned middle of 2007. This was a little harder than usual one as that is when we cleaned up the whole top of the bank.
This was Aug this year

I prune them once sometimes twice a year Gail those taller ones I have so many.
The smaller more silver leafed Gb get the seedpods cut off all the time so probably trim them about five times a year, those love it they are not even as high as me so I am able to reach all over those two shrubs, I hope they don't die soon as they would be around seven years old..
Yes that is right too much rain no wonder it came tumbling down..
No I don't let mind get to that stage of your top pic..
But all mine look like your bottom pic except the two smaller ones they get flowers all over the rounded shaped bush and not up in the air
