Tall Tetes

I got a bag of Tete-a-Tete at a big box sell out last fall, stuck them in a pot, put them behind a couch on the porch which had been too cold in the past, and forgot them.
The tall one is 17″. I wonder if eventually he would have peeked over the back of the couch, stretching for the sun.
No blooms outside yet.
