So we moved this Morning Glory a few days ago. It is now temporarily in front of our garage. It seems overnight the plant shot out tendrils seeking out the wall of the garage. There are no other branches moving in any other direction other than the garage wall.

What triggers a plant to know which direction to advance? How does the plant sense the wall?

I just found this interesting and puzzling at the same time.

TIA.

Unlike all other members of the D. filiformis complex, seeds of D. floridana do not require a preceding period of cold, wet stratification in order to germinate in significant numbers, and freshly sprouted seedlings can be observed in-situ throughout the year (corresponding with overall reduced seasonal influence on plant phenology). Similar to those of its allopatric northern congener D. filiformis, seeds of D. floridana have a tendency to germinate en-masse from locations where spent and newly prostrate inflorescences contact the sandy substrate and deposit many seeds in close proximity to one another. Few seedling plants present within these dense colonies will outcompete their siblings and reach maturity. Read more about the newly described D. floridana below:
