Littlebin and Legalily, it really depends on the size of the root you planted and your specific growing conditions if you're talking about peonies. The really small roots that typically come from Walmart, Home Depot, etc can take 3-4 years to bloom most places, I've had some bloom after 2 and some that still haven't bloomed after 5. Roots with 3-5 eyes and a nice sized feeder root can sometimes put up at least 1 bloom first spring if you good luck--most of mine don't bloom until the 2nd spring. Fertilizing with an organic bulb fertilizer and Azomite has improved the odds for me a bit. If you're wondering about what a good root size looks like take a look over the last few pages of this thread, those peonies from Brooks, Adelmans, Hidden Springs, etc are the ones that'll bloom first spring in most places. That's assuming you're planting in the fall for the next spring, I've only had a spring planted bare root peony bloom that same spring once in all of the years that I've grown peonies.
