I have for the first time this summer planted plenty of hyssop (loved by bees, scented and pretty in blue, white and lilac) but am at a loss regarding cutting down once flowering is over. My instinct tells me to cut down to the base in spring. Does anyone know how to keep this perennial going? Internet and books don't say about pruning.

Not sure I understand the 'thank you' process and hope you get this ... spritzhenry ... Yes, I did get a second flush too, going on instinct and dead-heading earlier, and following your advice will now trim my hyssop lightly in the spring as I like to leave the seed heads for the finches during the winter. Many thanks.

You did the 'thank you' bit exactly right, Avkg, and I got a message to say you had replied. :-) You're very welcome, by the way. Finches don't come into the area where my Hyssop's planted, I'm not sure why.

It's evergreen or semi-evergreen, and I just dead-head mine when the flowers go brown. Sometimes I have
to cut it back a little in the spring if the growing tips get frosted.
When I dead-head in the summer, I get another flush of flowers, by the way.
