vadub Posted August 27, 2013 Share Posted August 27, 2013 I've been interested in green roof technology for a while and have been thinking about introducing a species that would resist the nearby colonization of wind and bird-shit-bourne weed species.Is anyone familiar with hardy groundcover like sedum or other stonecrops that exhibit allelopathy or in general suppress the growth of other species?

EthnoGuy85 Posted August 27, 2013 Share Posted August 27, 2013 Sempervivum grow really thick here and choke weeds out. And they're very cold hardy here as well. 1 Quote Link to comment Share on other sites More sharing options...
vadub Posted August 27, 2013 Author Share Posted August 27, 2013 Thanks for the input. Whats great about various sedum species is they resist damage when walked on (during maintenance). Semp's fit the bill as well but I'm not sure how they would bounce back when intermittantly trampled upon. Quote Link to comment Share on other sites More sharing options...
EthnoGuy85 Posted August 28, 2013 Share Posted August 28, 2013 Mine get stepped on about once a week and seem to do fine. It tends to encourage them to spread or pup more. Quote Link to comment Share on other sites More sharing options...
