Nepeta 'Six Hills Giant'

You can’t beat the vigor of Nepeta 'Six Hills Giant,' a workhorse catmint that produces sprays of purple blossoms over the long haul (June to September if deadheaded) and is loved by pollinators. It looks so much like Lavender that it will fool your neighbors into thinking they’re in Provence.

Most Nepetas are thrifty plants that prosper in average, well-drained soils, and the majority offer deliciously fragrant, gray-green foliage and numerous spikes of small flowers, generally in the blue to purple range. They are durable, hardy, and pest free. Like Catnip, the best-known member of the genus, Nepetas may send felines into a frenzy.

We want our customers to receive strong, healthy plants that are ready to thrive in their gardens and homes. Here's what we'd like you to know about our shipping practices.

Delivery Timing

We aim to deliver your plants at as close to the proper time for planting in your area as possible. To do so, we consider the USDA Hardiness Zone to which we're shipping, current and forecasted weather at the destination and along the shipping route, and whether your plants are ready for transplant.

In spring, we ship first to the warmest regions and move north as planting conditions improve. For fall deliveries, we begin with the coolest regions and work south. We frequently adjust shipping schedules when extreme weather could put plants at risk while in transit or soon after arrival.

Because different plants reach readiness at different rates and are weather-sensitive in varying degree, a single order may be delivered via multiple shipments. Plants sold as part of a collection, or that are otherwise meant to arrive together, will be shipped together. Please contact our customer service team with two weeks' advance notice if you anticipate being away at the expected time of delivery. 

Tracking information for each package is delivered via email. 

Plant & Container Sizes

We deliver plants in various sizes and stages of growth, and the product detail pages of our website indicate the form and/or pot size in which the plant will be delivered. Pot sizes range from 1 pint to 1 gallon and larger. Many perennials, roses, shrubs and vines are delivered bareroot - that is, not in a container at all. Bulbs and tubers are generally delivered bareroot and fully dormant. We choose container sizes and delivery methods based on how each plant grows best, how we can minimize transplant shock, and how to minimize unnecessary bulk/weight in shipment. 

Caring for Your Plants Upon Arrival

It is important to acclimate greenhouse-grown plants to life outdoors. All plant shipments include simple instructions for handling your plants upon arrival. Further how-to information, including planting instructions, is available on each plant's product page.

Latin Name Pronunciation: nep'eh-tuh

Plant Nepeta in full sun or partial shade, and in well-drained soil. Tolerates drought. Cut plants back hard—to just a few inches tall—after the first wave of flowers to keep plants compact and to encourage repeat bloom.

Cats are almost as enamored of Catmints as they are of Catnip (which belongs to the same genus). You may need to protect plants (especially the first season after planting) to prevent them from being mauled. The foliage of N. nervosa lacks the spicy scent produced by the leaves of the other Catmints and is probably less attractive to cats.
