Can't see your pictures. Can you do screen grab and post it in your message?

But Pelargoniums will grow over 6 feet tall in climates where they don't get killed off by the winter. You often see them growing against walls of houses.

Thanks. These were growing against a wall. (No picture as I no longer have the disk.)

Not looked at the clip but pelargoniums are perennial shrubs whose stems become lignified with age (bark on trees is formed from lignin) so in a suitable climate I can imagine them getting quite big.
