Growing & using Giant Catmint

Giant Catmint in full bloom in the garden

This three-inch pot of Giant Catmint planted in early spring makes a striking display with its tall spikey purple stems by early summer. Giant Catmint is a much more prolific bloomer than the traditional Blue Wonder Catmint and is about a foot taller when in bloom.

Giant Catmint with Blue Statice and Purple Foxglove in May

Here is the same view in May, the following year. The darker purple flower is Midnight Blue Statice.

All catmints benefit from trimming around the middle of July. If they have not started to rebloom, they can be cut back to about two inches above the ground. If you are running late and they are blooming again, then just look for the old woody stalks and cut them all the way back to the main part of the plant. If you miss this pruning that is fine, just cut them back at the end of the season so the next spring they will be nice and clean.

Fragrant new leaves of Catmint

Reminescent of cinnamon, Giant Catmint leaves are both beautiful and fragrant. Humans are not the only ones who appreciate this fragrance, Catmint is related to the feline favorite Catnip. While most cats prefer Catnip, we have known cats to go wild over Catmint as well. In fact, there are many other plants that cats like.

Catmint is one of the six plants chosen to be in our English Cottage Herb Garden Six Pack and in our Zone 5-11 Fragrant Herb Garden Six Pack. It also makes a fun addition to our Edible Flower Garden Six Pack.

This plant is sometimes available in plug trays. These trays hold 128 of all the same plant. They are a great low cost way to fill a lot of space. Each cell is 3/4 of inch by an inch. Check here to see if Giant Catmint Plug Trays are available.
