Pycnanthemum Muticum ‘Mountain Mint’

Trial: Perennial

Years Trialed: 2000, 2001

Good Qualities:

Year 1:

Great foliage fragrance (4); Usable at many stages of development, vigorous; These looked dead when they arrived but we planted anyway. We had a terrible summer with no sign of any plants. This fall we’ve had a lot of moisture, cooler temps and when observed November 10th, 15% of the plants were alive. We expect next year they will take off and fill the bed. The 15% we have currently look very good. I think this will be a good plant; I like that it grows quickly and establishes itself even in less than perfect conditions; Very vigorous.

Year 2:

Very vigorous, nice fragrance, long harvest period; Nice minty fragrance, nice light green filler; This one came back to life, we have 5 plants alive and its 36; tall, we did not cut any of it so it would become better established but it will be nice; This one looks like it should work, smells good, tall strong stems, green color.

Problems:

Year 1:

Weak, sprawling stems; Prostate growth habit ‘ poor cut quality.

Year 2:

Flowers turn brown rapidly, never looks ready to cut.

Comments:

Year 1:

Several plants did not flower; Need to grow 1 more year, to see what to do with this plant; We used strictly as fresh and it makes an excellent filler.

Year 2:

Good new foliage/filler; Perhaps attempt to market as green without flower.
