Most of them, it seems. Currently, nineteen out of twenty-one haven’t kicked the bucket.
Here’s what the roof looked like as planted, back in May.
Currently exploding are the carex secta, virgata, and fagillifera, at the top of the roof in the driest and windiest part. Down at the bottom of the slope, the pratia angulata/panekenake seems very happy. Somewhere in the middle is the leptinella, coprosma prostrata and acerosa, doing quite nicely, although the acerosa is pretty shaded by the trees to the north. The ferns in the darkest and wettest far corner are not dead yet. One of the muehlenbeckia complexa/puhuehue died straight away, the other is hanging in there, despite being in similar conditions. One of the hebe albicans got heavily shaded by a branch before I cut that back and looks like toast, the other is fine.
This suggests to me that the tussock will survive on the house roof, so I think we’ll plant some next winter. It’ll be good to see it standing proud over the low succulents and seddums. The only other tall stuff we have up there is hebe stricta, which I like, but grows everywhere and gets so big (above head height) that it’ll fall over in the thin soil on the house roof.
