1 -This plant appears to be the annual Balsam plant (Impatiens
balsamina). It grows easily from seed and may also
propagated by cuttings. It has many rose-like flowers that
grow close to the stem. It often branches in older plants.
The stem is quite succulent in nature. - Sherlock
2 - Not sure but is it Oleander?
3 - Impatiens balsamina, or old fashioned balsam. The
plant is also called "touch me nots" because of the way the
seeds are propelled from the pods when ripe. Hope this
helps. - Charlene Schneider
