Cardinal Climber vine in the backyard to attract hummingbirds and butterflies

This is an update on our annual Cardinal Climber vine that is now nicely flowering in the middle of September. The red trumpet flowers are timed so nicely for #Hummingbird #migration. The Cardinal Climber vine (Ipomoea x multifida) is a hybrid cross between the cypress vine (Ipomoea quamoclit) and the red morning glory (Ipomoea coccinea). We purchased a packet of seeds years ago, and now just harvest seeds each year for our next year's planting.

We live in the Houston Gulf Coast area in zone 9a and directly plant Cardinal Climber seed in late March to very early April. If you live in more northern areas, I recommend starting the seeds indoors 4-6 weeks before your final frost. We have success with soaking the seeds in warm water for 24 hours before we directly plant into the ground. If you soak your seeds they will germinate faster. The vines take around 12-14 weeks to start blooming, so time this for your particular area.

This vine is truly an annual and will die at the first frost. The seeds do not survive outdoors in freezing temperatures, so be sure to bring the seeds in for the winter if you want to plant again in the springtime.

It is also good to note that the Cardinal Climber seed is true to the seed, meaning it will not revert to either parent when planted. At least we have never had that happen with our seed.
