Decora shooting like crazy... plants had two small culms each last year and are 1-1/2 years old. One plant has 17 shoots, 14 with good upsizing. They have run about three feet.
Congesta just starting to shoot... Only a few shoots. These were large field digs last fall so no running yet. Bamboo is the most exciting plant to watch!! Best of luck - John

Im envious its only gotten above 70 a couple of times and none of my outside running bamboo is shooting yet.......im a little worried but I know it will shoot most likely in late May

That's pretty much the same for me. The bamboos that we have in common such as f nitida, atrovaginata, parvifolia, nigra, and rubromarginata still aren't shooting for me yet. I put an olive colored plastic mulch around some of them to heat up the soil to speed up the process and I might leave it on throughout summer/fall to speed up rhizome growth too.

The only thing that has come up so far in the ground is:
F-Rufa-After middle of March
P Aureosulcata April 19th
P Edulis April 27th-Right when I was getting worried about it.

Potted bamboos almost always shoot earlier so those don't count.

Yea the running Bamboo that is shooting outside for be is my newest one Qiongzhuea tumidissinoda which I have planted in a 4'x4' cedar planter and its shooting well, my wife thinks im crazy I go out to my yard everyday and inspect all the bamboo to see if theres any shoots!

The Sasa veitchii is shooting, as are some of the Pleioblastus, but my big 'boos are playing it cool. The Phyllostachys nuda will likely send up a gazillion shoots this year as we had a mild winter, lots of snow cover and a warm and wet spring. Ka-BOING! Hoping the P. rubromarginata gets frisky too.
