those late frosts and/or freezes????

The only thing I can imagine is lack of adequate sunlight?

They're in full sun, so that wouldn't be it. Maybe the May freezes like Ken mentioned.

Mine did bloom but had a greatly reduced number of flowers. We did have the most bizarre winter weather (and spring weather, for that matter), so I'm going to chalk it up to that.

Ditto, bizarre weather here too.

didnt you mention that you noticed lilac lack of bloom this year ...

be interesting.. to see if the two ever dont bloom again in the same season ...

oh well.. the farmers lament.. there is always next year ...

btw ... in all my years.. i never grew baptista ... why ... are you zone pushing??? .. i mean. before i got addicted to hosta.. i used to buy everything .. and give it a try .. why didnt i ever run across this???

Baptisia australis is hardy to Zone 3.

I had blooms, but much less than usual. Must have been that late frost?
