Green Roof-[possible wildflower miniature meadow]

[teta]

Does anyone have any experience of this?.Any tips or suggestions or 'how to' sites?.Its for a garden store so maybe the not exactly the same construction values as thet for a house roof.

ooh it sounds lovely

Yep - DH did a gorgeous one last year - for a home office of a landscape gardener. I know he got sedum (came on the roll, planted up in an egg box style structure.) and after that took hold the landscape gardener planted up more grasses, alpines and meadow flowers...looked gorgeous!! If I remember correctly it wasn't as much of a pain that DH thought it would be! I'll ask him to give you some tips or where he sourced some info from

Apparently DH has admitted to googling 'green roofs' and then picking bits from each one that suited his project!

Most important thing is to make sure the roof is strong enough to hold it up - standard shed roof isn't enough.

If you go for sedum (which was excellent) it comes in rolls and you need to think about how you're going to get it up there....it's heavy

Me too Jeanjeannie!.Thank-you for asking your DH [he must be very patient at answering all these queries from MN].I was thinking about doing the wild flower turf - i think comes in 1.2 metre strips.Luckily we will be turfing at chest height and the roof will be long and thin.I think it will look really good though.Thank-you Lala et.al. for the idea!.

MissBehiving has her entire house covered in a green roof.

Apparently the wild flower turf looks stunning in flower, but very unimpressive out of season, whereas the sedums look reliably okay all year round. Presumably the landscape gardener was trying to balance out the two by taking a sedum background and planting up with additional wildflowers, but you're then moving towards a semi-extensive roof, and it would need additional soil, which means more weight, etc.
