Common Names:Cardinal Climber
Bloom PeriodStarts blooming in mid-summer and continues through Fall.
Both Cardinal Climber and Cypress Vine have similar flowers and are often mis-labeled, so look closely at the seeds you are ordering if you are really intent on growing a specific plant. Don't fret too much if you get the wrong seeds. They are both wonderful vines and very hardy growers.
Red Morning Glory has similar trumpet-shaped flowers, with the more traditional heart-shaped morning glory leaves.
The plants do very well in containers. Add a support in the container for even more height. They look wonderful growing around a tudor or obelisk, in the center of other flowers.
Soil: Cardinal Climber is not particular about soil pH, but something in the neutral range of 6.0 to 7.2 is best. It does not need a rich soil, although some organic matter will keep it growing and blooming without additional fertilizer.
Planting: The morning glory family does not like to be transplanted and most varieties are direct sown. Wait until after danger of frost to plant seeds outdoors.
The seeds of have a hard shell and germinate best is some type of scarification is done before planting. The easiest method is to soak them overnight. If you're really ambitious, you can rub them gently with some sand paper and then soak them over night. Seeds should germinate within 10 days.
Plant the seeds about 1/4 inch deep. Give the young plants a regular weekly watering of at least 1 - 2 inches, while getting established. Cardinal Vine doesn't like prolonged periods of dryness.
Maintenance:Cardinal Climber is pretty much maintenance free. It needs regular water, but shouldn't need fertilizer unless your soil is very poor. In that case, a side dressing of compost in mid-season, should be enogh. There is no need to deadhead the flowers or trim the vines.
In wamer climates, all members of the Morning Glory family (Ipomoea) can become aggressive self-seeders. So far, only the Arizona Department of Agriculture has banned their sale. Also, the seeds are poisonous, if ingested.
If Cardinal Climber is not a problem in your area, you can allow the seed pods to dry on the plants and then collect the seeds to plant next year.
