Anyone grow this? And any info on pruning would be very useful.

    I had this plant for 5 years.   Tough, very hardy, needed no pruning nor irrigation, untroubled by wind or freezing weather.  It stayed a dwarfish shrub, about 3 foot tall perhaps a little more.... flowers all over the bush, those little daisy like flowers for about 3 weeks in August.   I used to prune off the old flowers when they went brown but there's no need really, it was just being fussy.

    A dwarf shapely bush, perhaps a little unexciting?... I wanted something else eventually... but if I had room I'd still have it for it's fresh silvery leafage...

    I've never heard of this so looked it up.   Various sites suggest it's a good hedging plant in mild and coastal areas so no good to me in this garden then.

    It can be hard pruned or lightly pruned in April, according to need.

    I like the look of it so it's going on my wishlist for if/when I get a more sheltered garden.    Another gem Berghill.

    Not bad for £1-00. Good sized plant too, about as big as the one described by Salino.

    Slight error on my part as the one I wanted to know about pruning, is Olearia phlogopappa 'Comber's Blue'  It is very leggy now and I wondered about cutting it back to encourage shoots from the base.

    Neither of these will survive here outside, we are just too too cold, so I have grown the latter as a pot plant and it goes into the poly-tunnel for winter.

    ..you can't grow Olearia x haastii outside?   it had survived unscathed here for 5 winters down to -12 or -15 even and with full exposure.. and associated freezing conditions.... it's also planted around B and Q car park areas as landscaping... at least where I am in East Anglia....where it's left to grow unattended and somewhat unloved...  here it didn't survive my whims unfortunately...

    We have had those temps inside the greenhouse the last few winters.

    Not sure why some of these plants do not survive here. Hydrangea macrophyllas never flower and Dahlias get frosted off before they flower most years. We tend not to buy things which say 'needs a warm sheltered position.  Sadly we do not have any South facing walls either.

    Same here Berghill.   I don't buy anything that says it's nesh but Bishop's Children dahlias do OK in pots and this year i've had a couple in the borders as they got going so early after the exceptionally mild winter.

    I can't get flowers on hydrangea macrophylla either but I have recently discovered the paniculatas which are a joy and now I have several.     I bought and planted a new HP Diamant Rouge at a plant fair a few weeks ago and it has turned a fabulous deep, rich red in both flower and foliage.   Luscious.
