This is a great plant with those huge pink flowers that have just a hint of lavender. It's also called Diez en la Manana because its popular in the barrio areas of Mexico and the flowers close up about 10 am. Another name is Tree Morning Glory and as you might guess it grows pretty tall - here to about 8 - 10 feet - on woody stalks. Sometimes the shoots will die back as much as 2 -3 feet with cold weather but the plant grows back as soon as the weather warms again in the spring.

The seeds are fuzzy and look like kitten toes - hence the name you're familiar with.

Some nurseries carry this plant.

Just google Ipomea carnea
