I agree with the last two posts.
My first cobra can stand any amount of heat my greenhouse can throw at it,and its only stood with the sarras(no special watering).
BUT "OTHELLO" is different.My first one grew to 6" easily,dinner time it was o.k-tea time it was dead,completely collapsed and shriveled and it was grown there all its short life.
My next othello is grown much cooler and is now sending out a stolon,so it must prefer the cooler conditions,something the last one never did.
you taking notice Fred!
