Slimleaf or Narrowleaf Milkweed is a small, thin leaved species native to the Great Plains and westward. The Mississippi River makes an effective eastern border to the native range of A. stenophylla. To the west it continues into Montana, Wyoming, Colorado and New Mexico.
An interesting prairie species, it has long, narrow leaves that are useful for identification purposes. Alternately arranged leaves are up to 6″ long but only 1/4″ wide and are slightly folded along the midrib. Flower clusters of up to 15 greenish white flowers are produced in mid-Summer. In some states Slimleaf is listed as endangered.
Unlike most other milkweeds, Slimleaf can only reproduce by seeds; it does not produce underground rhizomes.

Slimleaf or Narrowleaf Milkweed requires full sun and dryer soil types for success.
We grew dozens of this species in 1G containers last year in the nursery. As the scientific name implies (stenophylla = narrow leaf) we found the whole plant to be rather narrow and spindly in its first year. The potting media we used was 100% shredded bark. In retrospect this media may have held too much water thus reducing growth. This year we’ll us a media blend containing a large amount of non-calcareous sand and/or perlite. This will increase the drainage and hopefully promote better growth. We think that this species holds great promise for growing as a patio plant in a large container.
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.
