Blue Sage is an elegant native perennial known for its tall spikes of soft sky-blue flowers that bloom from midsummer into early fall. The two-lipped blossoms cluster along square stems, creating a vertical accent that stands out beautifully in prairies, meadows, and sunny garden borders. Its aromatic foliage and upright form give it a refined, airy presence in native plantings. Long-blooming, drought-tolerant, and highly attractive to pollinators, Blue Sage brings color and movement to open landscapes.
Overall height at 2–4 feet.
Blue Sage serves as a host plant for several native moth larvae and is occasionally used by butterfly species that rely on members of the mint family. While no butterfly species are confirmed to use Blue Sage as a primary caterpillar host, butterflies such as the Eastern Tailed-Blue, Cupido comyntas and the Gray Hairstreak, Strymon melinus may be found in habitats where it grows. Its nectar-rich flowers attract bumblebees, long-tongued bees, skippers, and small butterflies throughout the summer, and its stems and foliage provide shelter for beneficial insects.
Historical accounts note that plants like Smooth Blue Sage were used by Indigenous peoples in traditional herbal preparations, including teas and poultices for minor ailments. These uses reflect cultural tradition rather than modern medical guidance and should be understood as historical context rather than recommendation.
Blue Sage provides strong wildlife value by supporting pollinators, offering habitat structure for insects, and enriching the ecological diversity of prairies and meadows. Its drought tolerance, long bloom period, and graceful form make it an important species for sustaining beneficial insects in sunny native landscapes.

Blue Sage grows best in full sun and prefers dry to medium, well-drained soils, thriving especially in sandy, gravelly, or loamy prairie sites. It tolerates heat, drought, and lean soils once established, making it ideal for restoration projects and low-maintenance gardens. The plant forms tidy clumps that remain upright throughout the growing season and spreads modestly by seed without becoming aggressive.
Please note that Riverside Native Perennials (RNP) only ships our potted “35” product via USPS. We generally can have your plants boxed up and ready to go within two or three days. All other products including our flat of plugs, 1-gallon and 3-gallon containers are only available for nursery pick up in Delaware, OH. For large orders of any of our products we can arrange shipping at an extra cost. Please contact the nursery for additional information.
It’s important to note that when we send plants to you, presentation is everything! We recognize that you’re expecting healthy plants to arrive safely on your doorstep ready to be planted and that is what we’re selling. Further, we want you to know that while we are a fully licensed and inspected perennial nursery in the state of Ohio…we are in Ohio! That means we are subject to Ohio weather. The average frost-free date for our area is May 15. So even though you may live in Florida or California your plants are growing under Ohio conditions and we do not heat our greenhouses due to the expense. Our plants may be slightly delayed but again it’s because we’re in a Zone 5 area. Because we ship nationwide, we ship plants at all times of the year. If it’s winter in Ohio, you’ll be getting dormant plants. If it’s spring or summer in Ohio, you’ll be getting plants of various sizes that are actively growing. Plants shipped during fall in Ohio may be dormant or may be heading towards dormancy. This is all natural and we do not try to modify or prolong the growing season other than to grow them in an unheated greenhouse. Even in an unheated greenhouse our plants are much further along and growing well early in the spring than if they were planted outside in Zone 5. If you would like additional information about sizes for a particular species, please contact us via email.
In 2021 RNP partnered with a shipping professional to design and develop a shipping system that could reasonably be expected to survive the USPS mail room and transportation process. After several design sessions and going back to the drawing board on more than a couple of occasions we created a shipping box system that, to us, is bulletproof. It is strong, lightweight and, to date, has not failed in shipping nearly 150 packages of plants to all corners of the country.
Once selected from our greenhouse benches, your plants are placed into a small plastic bag to maintain moisture during shipping. To keep the soil in the pot we created a cardboard insert that perfectly fits into the top of our 35 containers. The insert has a cutout that surrounds to plant stem without damaging it. The plastic bag and insert are secured by two rubber bands. Each bagged plant is then placed into an individual corrugated cardboard box which perfectly fits the 35 container, and which locks it in place so that it will not move during transit. Four individual boxes are then placed into another, even heavier duty corrugated cardboard master shipping box. The whole effect is that of double boxing your plants. They are safe and secure for the long trip to your home landscape!
The system only works with 4 individual boxes being packed into a single master shipping box so we encourage you to buy four plants or a multiple of four plants. You can buy less than four plants but we will need to send all the cardboard for four plants in order for the shipping system to succeed as designed.
