Beautiful plant!
Where I live we have blazing hot humid summers and a lot of nights in winter that are at or below freezing. Even with two
two week long cold snaps of temps in the 20's these plants survived.
With some light covering the bushes did die back to the ground, but as of now (May 14) they are tall and lush and becoming covered in light purple flowers.

Great little plant which is easy to grow. Stays fairly contained, and a must have for bees, butterflies, and hummingbirds. Very nice licorice scent.

Seeds are very fine, and need to be sown close to the surface or on the surface of the soil where light can reach. Keep moist until germination occurs, then only average or little watering in necessary.

Cool plant. When I leave the house to go to work in the morning, there are at least 5 bumblebees on this flower. Same thing as I return 8 hours later. They love this plant and I enjoy the flowers attractiveness.

I live at 7500' in the Flatirons. Lowest recorded temperature was -7F last winter. Planted 1 plant 2004. It went from a few stalks to many this summer. It's now about 3' in diameter and 50" tall with dozens of flowers & many honey bees so I presume seeds are fertile. Added 8 more this Spring & all have done very well. Generally am plagued by animals- deer, rabbits, squirrels, chipmunks, gophers which eat everything but don't seem to bother mints. Have so far collected about 2 tbsp of seeds (smaller than poppy seeds) but don't know what to do to germinate them. Any tips will be greatly appreciated- plan to plant one large area of yard next spring. Seed collecting seems to be easy. Cut off dried blossoms and rap stem on edge of large soup bowl. Dozens fall out.

On our morning tours of the garden my wife and I often find this plant full of bees clinging to the blooms waiting for the heat to activate them. Then they go wild on the pretty purple blooms later in the day.

The blooms in the fall smell just like you've opened up a package of fresh black licorice.

An easy plant... It has done well in many different places, with regular watering or not. Makes a great back of border plant, with nice dark leaves and pretty purple blooms.

Taller than and with more crinkled leaves than A. foeniculum they are quite similar in appearance and flavor.
