Cardinal climber (Ipomoea × multifida) is one of those plants that fully lives up to its name. The blossoms of this hybrid plant are a true cardinal red, and the vine reaches for whatever it can grab. This is a very graceful, airy annual vine, related to morning glory (one of the parent plants of this hybrid). It blooms profusely throughout the summer and the red, trumpet-shaped flowers are big favorites of hummingbirds and other pollinators. The bright green leaves are triangular, with deep, narrow lobes that give them a lacy appearance resembling that of small palm leaves. The tubular flowers are red, with white or yellow throats. Five petals overlap to form a swept-back pentagon at the opening.
Cardinal climber is often planted near a trellis or other structure that it can climb; it can also be used as a dense ground-cover. The delicate, lacy leaves form a peek-a-boo screen rather than blocking the view entirely. This makes them great for training over an arbor or trellis. They are also a good choice for softening a wall and adding an airy feeling.
Cardinal climber can also be grown in containers. Add support in the container for even more height. The plant looks wonderful growing around an obelisk, in the center of other flowers.
Hey garden lovers! Today I’m super excited to share everything you need to know about the gorgeous Cardinal Climber (Ipomoea sloteri). As someone who’s been growing these beauties for years I can tell ya straight up – it’s an annual vine, not a perennial. Let’s dive into all the juicy details!
What Exactly is a Cardinal Climber?
The Cardinal Climber is actually a pretty cool hybrid plant with an interesting backstory. Back in 1897 this guy named Logan Sloter from Columbus, Ohio, decided to play plant matchmaker. He crossed two plants
- Red morning glory (Ipomoea coccinea)
- Cypress vine (Ipomoea quamoclit)
Fun fact: It took him 11 whole years before he got a single seed that worked! Talk about patience, right?
Key Features of Cardinal Climber
Let me break down what makes this plant so special

- It completes its lifecycle in one growing season
- Dies after frost hits
- Needs to be replanted each year in cold climates
- Might reseed itself in warmer areas (but don’t count on it!)

Fertilizer
Cardinal climber rarely needs feeding unless the soil is very poor and infertile.
How to Grow Cardinal Climber From Seed
You can sow seeds directly into the garden after danger of frost has passed to a depth of 1/4 inch. Or, start seeds indoors four to six weeks before the average last frost date of spring.
The seeds have a hard shell and germinate best if scarification is done before planting. The easiest method is to soak them in water overnight. If youre really ambitious, you can rub them gently with sandpaper and then soak them overnight. Seeds should germinate within ten days. Give the young plants a regular weekly watering of at least one to two inches while they become established.
