Our plants are grown all over the country and lead time on items may be different because of this. Once your order is placed, you will also receive the specific shipment time-frame information as part of your order confirmation. Once an item ships, you will receive shipment notification and tracking numbers, so you can follow along while your plant travels to your doorstep. We use FedEx, UPS, or USPS at our discretion.
Due to winter weather we have put a hold on shipping to the areas shown below in grey. You can still order now and we will ship the plant to you during an appropriate time for your zone.

- Container Plants: Grown in pots with soil, sized by container volume and plant age

Power up your butterfly garden design with a charge from a bright red, native flower. The big and bold Cardinal Flower (Lobelia cardinalis) draws your eye and adds a tremendous vertical accent to the garden!
In the wild, these natives grow near water, in ravines, stream banks, swamps, and low pastures. So you know they will do wonders in your landscape! The leafy green clumps form more and more spires with each passing year! Snip a few stems for your bouquets to add a vertical focal point indoors too!
Fabulous red flowers climb along a long spire from the bottom up, and act as beacons for jewel-toned hummingbirds and local butterflies! The long bloom time and rich nectar are quite showy! These wetland natives grow throughout USDA zones 3 to 9 and spread into 2-foot wide clumps of lush greenery with their tall spires full of long green foliage.
Planting and Application:
Outstanding back-of-the-border plants in the moist Cottage garden border or Rain Garden. Add another dimension to your garden by using them around your ponds and bogs adds another special dimension, where you can see the long red spears reflected in the water!
For the most powerful impact, we'd advise dedicating enough space to plant several of these in a gentle zig-zag or row, since groupings attract the attention! These are truly effective when massed together! Hummingbirds and pollinators love it, the bold red color pops and the strong vertical accent draws your eye. Win, win, win!

#ProPlantTips for Care:
This is one of the showiest of all of our beloved North American prairie plants, and it tolerates moist soils. You don't even have to worry about the drainage of your soil as it tolerates moist living conditions beautifully. Plant in full sun for the strongest stems. These cold-hardy perennials will die back in the fall and need a good trim in the spring before new growth emerges. You can deadhead your plant to encourage new blooms all summer.
- Full Sun
- Grows Well in Moist Soils
- Moderate Moisture Needs
- Clean Mounds in Spring
- Hardy Native Wetlands
Order the big bold blooms of the native Cardinal Flower and impress your pollinators and hummingbirds. Find these and other perennial showoffs at Nature Hills Nursery!
Because it's a native plant, it does a little "too well" in certain areas. Please know that Nature Hills uses Plant Sentry™ to ensure we follow all local, state and federal regulations for plants that can become invasive in your area. We've got you covered!
