I bought 4 types from Thymegarden this year and they have really grown. They were planted around 3/30.
Nugget- about 16 ft. Grew 6"/day and was first to put on cones. Lots of them.
Willamette- about 11 ft. slowed down and bushed out. No cones yet.
Cascade- planted late- about 10 ft. but growing 6" a day. Lots of buds, no cones visible. Expect it to grow lots more. 2 big bines.
Centennial- Very poor growth because I put it in a bad place. Need to transplant.
I live in south Texas and these plants take lots of water. I give them a gallon of rain water a day at least. I got them going on Greenlight root stimulator and starter solution from HomeD.
