Robust minty-scented foliage along sturdy stems offset an explosion of lavender-purple plumes that appear in late April. Whispurr™ Blue Catmint, Nepeta x faassenii Whispurr™️, is a vigorous long-season bloomer, putting on a colorful show from late spring through early September.
Whispurr™ Blue Catmint is quite frost tolerant and hardy in Zones 4-9. It maintains a compact form and grows up to 28 inches tall with a spread of 22 inches. The densely packed foliage has a lovely mint fragrance. This is a much-loved magnet for butterflies and other pollinating insects. Its mounding habit and long blooming season make a vibrant colorful impression when planted en masse along paths and walkways.
Whispurr™ Blue Catmint Care
Find an area in your garden where Whispurr™ Blue Catmint will receive full to partial sun, at least 5-8 hours per day. Whispurr™ Blue Catmint will benefit from being planted in a location that has afternoon shade in very hot regions. It thrives in average, well-drained soils. Water regularly and deeply during the first growing season to get the plant off to a great start. Once Whispurr™ Blue Catmint is mature, reduce watering frequency, and allow the soil to dry slightly before watering again.
Whispurr™ Blue can easily be grown in containers; be sure the container has ample drainage holes and well-draining potting soil. Whispurr™ Blue Catmint needs little care other than removing spent flowers to promote extended blooming throughout the season. Propagation can be done by division every few years or spreading the dried seeds around the base of your plant to encourage wider spread in the following years. Whispurr™ Blue Catmint is cold hardy down to Zone 4; in colder regions apply a few inches of natural mulch around the root area for added protection.
Whispurr™ Blue Catmint Spacing
Whispurr™ Blue Catmint is a wonderful addition to pollinator gardens and perennial beds, works very well as an edging along walkways, and can easily be grown in containers. To avoid crowding, space Whispurr™ Blue Catmint 22-24 inches apart on center from other plants to account for its mature spread.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
