In the nursery we grew this and other milkweed species in 15 gallon pots situated to get full morning sun and afternoon shade. Potting media was a shredded bark mix (pine fines) that we watered occasionally. Plants were started in the greenhouse from seed in early spring and by June they were already blooming. Unopened blooms are pink-tipped in color and open to brilliant white. We transplanted these seedlings into the 15G pots in later June and they sized up very well producing inflated pods filled with numerous seeds. Plants reached nearly 3′ before frost stopped all growth. We’ve stored this and all our 15G milkweeds in an unheated greenhouse to see how they come through winter. NOTE: they did come through winter in the unheated greenhouse and grew well their second year.
As the common name implies this plant likes it wet. In the 15G pot we figured it was deep enough to hold adequate water. We watered them occasionally but never saw any evidence of wilting or distress. It was a very easy to plant to grow for us. From germinating the seed to the finished plant we experienced no problems. Next year we’ll move these to an area where they get more sun just to see how they do.

In your home landscape this plant would make a great mid to background plant based on its final height planted in a moist to wet area. If you have a water feature in your landscape this plant would be a terrific addition. You could plant it right along the bank or edge of a pond or if you have an ornamental pond keep it potted and situate it in a shallow area. Even in something as small as a half wine barrel that is sometimes used as a decorative water feature this plant would be at home in a small pot. Bog gardens would also be enhanced with a potted Aquatic Milkweed or two. If your landscape does not have adequate soil moisture to support plants requiring moist to wet soil consider purchasing a drip irrigation system that can snake under the soil or mulch and water with a battery-operated valve timer. Water use is minimal and the water is delivered right to the plant so there is very little lost to evaporation or runoff. Another possibility is to create your own bog. To do this excavate a shallow depression, line it with heavy gauge plastic or roofing material, backfill with the original soil and water heavily. The “bog” will hold rainwater much longer than the surrounding soil and allow you to enjoy and entirely new palette of plants; those liking wet conditions.
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.
