My agastache foeniculum disappears every winter and reappears as a few
chance seedlings only in the immediate vicinity. It grows quickly in the
heat of the summer and flowers from about mid-July on here - (zone 5/6,
inland Northwest). I would not describe it as invasive - and self-sows much
less abundantly than, say, cosmos, california poppies. or alyssum.

I see this a member of the mint family....if I even hear the word
mint.....I
think of an invasive plant.

Is it?

A: as bad as mint?
B: not nearly?
C: not at all?


Mine hasn't been invasive. It tends to form slowly growing clumps rather
than aggressive root runners like spearmint. The only issue is that it
produces lots of seeds and they tend to germinate at a rather high rate.
That said, the seedlings are very easy to kill by simply cultivating the
soil when you see them sprout. I started some from seed about 5 years ago
and they did really well. Unfortunately, they seem to have died off this
winter. I only have a few left, so I am letting the seedling mature and
will thin them later. I always leave the seed heads alone for winter
interest and wildlife food. If you removed the flowers before they set
seed, you would eliminate the issue.
