Description: These plants have a basal rosette of dark green foliage out of which grow thick, leafy stems forming a spike of scarlet, lipped flowers. The lower flowers will form seed pods while the upper flowers continue to grow and bloom. Plants self sow often. Cardinal flower grows native along streambeds all over the Southern United States and is a real treasure in the garden by providing one of the truest reds available. Is thrives in areas where other perennials would rot and adds bold color to shady corners of the garden.

Hardy: Zone 3

Bloom Time: Mid summer - early fall

Height: 24'' - 36''

Spacing: 15'' - 18''

Sun Needs: Part shade

Water Needs: Low but the soil needs to be consistently moist to almost wet, do not let soil dry out between watering.

Outstanding Features: Attacks butterflies and humming birds

Uses: Cardinal flowers are fantastic near water features, so consider using around ponds, pools, stream beds or boggy areas. They also do well in shade borders, woodland areas, hummingbird gardens, for a cut flower border or native, naturalized areas.

Tips: To collect seeds allow pods to dry on plant; break open to collect seeds.


  1. Such great information!! Thanks for sharing and I am a new follower! Hope you have a great rest of your week!

  2. I can't wait to plant cardinal flower in my butterfly garden. I like that it's a taller part shade plant. Most of what I planted in part shade is pretty low.


Thanks for your thoughts! I read each and every comment :)
