The Garden Girl – Nepeta Six Hills Giant

June 22, 2014 14:00 pm · 6 comments


Nepeta Six Hills Giant is a summer showstopper with its icy gray foliage and periwinkle flowers. It is heat hardy, sun loving and water-wise, making it a more than desirable selection for any Claycord landscape, container or garden. It is very predictable and is also recommended by the Contra Costa Water Department and East Bay Mud as a drought tolerant perennial.

Nepeta Six Hills Giant is one of the tallest in the Nepeta family. It can reach 30” tall and about half as wide. Other fabulous family members to Six Hill Giant is ‘Walker’s Low’, a former perennial of the year, ‘Blue Wonder’ and ‘Snow Flake’ with pure white flowers.

This plant is a herbaceous perennial. This means that this plant has a period growth, a period of bloom, and a period of rest. Nepeta reemerges from the ground in March, and begins to grow. Once spring starts to heat up, Nepeta begins to flower. The flowers cycle, and with deadheading, Nepeta can bloom off and on the entire growing season. That means your plants will bloom from May through early October.

Use Nepeta in the landscape to accent foundation plants like phormium, rose bushes, crape myrtle, agapantha, and lavender. It also can be used to accent hardscape. Install Nepeta along a retaining wall, or next to a decorative boulder.

Nepeta attracts honeybees and can be utilized if planted near a vegetable garden, or fruit trees.

Nepeta is commonly called Catmint. The aromatic foliage is very tempting to our feline friends, they love to rub and chew Nepeta’s leaves, so you may want to consider that when you pick the spot to install.

Nepeta thrives in our soil and climate. It is a wonderful consideration.

Happy gardening!

Sounded great til you got to the cat part. Say, are there any plants that will REPEL cats?

Fiddy…..funny thing was that NONE of the cats we ever had in our house paid one bit of attention to the freshly-cut catmint I brought inside. (The fragrance is faint and delightful) But all the cats LOVED it once I had hung clumps of it it upside down to air-dry and then crumbled it off the stems.

Dried catmint stores well if bagged and kept in the freezer. Also, after washing and drying the cats’ knitted fabric toys, you can store the toys inside a bag of dried catnip and bring one back out for a surprise.

The plant is truly lovely! Oh……and the catmint bush did not attract more feral cats into our back yard, either!
