Yes Daniel, Two different plants of the same species found close together! Photographs no. 1-3 are the same plant. Photo no.4 was growing close by!
Looks like two different plants to me. Not close enough to to make out the details. The first reminds me of an overgrown balsam--Impatiens balsamina, but that's a wild guess. Number 4 looks like Ipomopsis, but too woody I think.
Thank you Mr. Eric. I should have numbered the small bush nos. 1-2,4 whilst the tall bush is numbered 3. Probably they are not spontaneus, probably escaped cultivars!
