Fleabane

[Twotimesrhymes]

I bought this in the past and it died in the Frost.. any tips ?
We live in a rural cooler climate / think of north Scotland (rocky ground)
I was going to put two out in a rockery area ? Sorry for Italics.

Which sort do you mean - I think there's quite a few things called 'fleabane' (Erigeron karvinskianus - 'Mexican' Erigeron glaucus 'beach asters' ... probably others ... common fleabane is Pulicaria dysenterica)

Hi thank you it’s this type

karvinskianus
small white pinkish daises

It's not hardy in Northern Scotland.

Mine self-seeds, often into pots. Perhaps if you plant some you can have some strategically placed pots which, if it colonises, you could overwinter somewhere frostproof?

It doesn't look the same, but I live in Scotland and I've used Campanula Poscharskyana (https://www.gardenersworld.com/plants/campanula-poscharskyana/) to a similar effect. Purpley-Blue and White varieties are available.

It is fully hardy even in N Scotland, is low growing and is bombproof. It is looking stunning at this time of year.

Unfortunately, Mexican Fleabane is unlikely to be perennial where you are.

Erigeron karvinskianus is a pest in my garden, I am forever pulling it up - but I live on the south coast. I didn't realise it wasn't hardy. It's survived the occasional snow and frost we get.
It self seeds very happily in crevices in our paving where there is very little soil or moisture, so maybe if you can plant it in a very well drained area it would survive your winters? (Pic below) I rarely find it self-seeding in flowerbeds so I assume it prefers very dry conditions.

I have Showy Fleabane. It goes -10 and (and often MUCH) colder where I am and i Fleabane survives ( hate the name Fleabane though 😂)

It certainly can survive some frost - I'm in Lancashire, the place I first noticed it growing in profusion was tumbling down the steps of sizergh castle in Cumbria.
But although I'm in 'the north' of England I'm right in the middle of Britain, the OP is presumably a lot further north!

You're right it doesn't seem to colonise flowerbeds, it probably does particularly dislike damp.
