I have grown Dragon King and it just sat there and dwindled and died after about 3 years.
I have ordered from Keast several times over the past 5 years and had good results. They send healthy plants -I have not lost any I got from them. Communication, ship date, packaging, identity ect was all fine. You should take recommendations from the Green Pages w a grain of salt, of course it all says nice things about companies because no negative comments are allowed, only recommendations.
