Expect shoots all summer where kept moist.

My potted S.f. has been shooting continuously since the spring.

My planted Ph. vivax, also.

Normal? I dunno, but that's my experience, this year.

I kept waiting for my spring delivered bamboo to stop shooting before I planted it. I finally gave up and planted the first 5 pots of Koi today, new shoots and all. Im going to do my 15 S.f tomorrow, new shoots and all. And all the rest in the coming week. I solemnly swear- I will NOT be overwintering any bamboo in pots this year!

Here in southern Alabama, mine has been shooting since spring. It is over an underground spring and seems to love it there. The later culms do get shorter compared to the first spring shoots but they are great for transplanting to pots or other places in your yard. I find it the most prolific and the best for privacy of all my many boos.

Around here, fastuosa shoots from late May to Nov. One year, I had a shoot come up so late that it stopped growing at 12 feet in height in late Nov, then continued its growth in Mar to full height, leaving a section of shortened internodes at its point of dormancy on the culm.
