Hi Nancy,
if you are using the herbs, then I would pinch off the blooms-seems they change when going to seed...
I think they will seed later in the season too if you want to save seed..
just my opinion..

the little aspargus fern you gave me at the Lou swap is doing good! It's putting out a 'bloom'???? --a little thin, tall thing-very cool indeed! It's on my Mom's front porch (for shade) and we are enjoying watching it..

have a great day!
