You should see at least the beginning of leaf buds. Mine are already out of dormancy and pushing new growth but I'm in a bit milder climate :-) And it is much too early to see anything that looks like a flower bud. It is also my experience that oakleafs need a little time for establishment before they start blooming freely - like a couple of seasons. You might see flowers this season but I wouldn't count on it.

You are going to have to wait some more time. Leaf out seems to be starting on those pics but they still have ways to go. Even more later on to open flower buds.

Leaf out and opening of flower buds happens first in the southernmost areas of the country (usually) and it is too early for me to see open flower buds here on the oakleafs so you should be in the same league too. Maybe 2-4 weeks later than mine start doing the broccoli thing. Mine started to open the leaves buds about 2 weeks ago and are still working on fully opening the leaves. On a normal year not influenced by El Nino, they would have waited until April to open those leaf buds.Flower buds would open "several weeks" later; maybe a month??? I have not timed them..

Now, one of my lacecaps is in the broccoli stage now even though its leaves are about still unfurling and about 1-2" long only. The mopheads are just opening leaf buds now; no open flower buds. PS - do not forget to start watching out for soil moisture issues.
