HI all,
Question 1 - in basic 101 for student like moi:
What's the difference and/or relations between Dracaena and Cordyline ?

I salvaged from a nursery what we call here in Israel Red Dracaena australis, and which is called in several sites - Red Cordyline - hence the above confusion - in Question 1.
The tall trunk (about 5 feet tall) is damaged - the "tip", the "heart" broke !
From the base there is a new healthy baby stem growing. - see in first picture
Question 2 - If i will cut the trunk just under the crown - see in second picture (at finger point) - will it yield/grow a split of trunks at the top (just under the cut) ? (the way Dracaena tricolor or red margins Draceena do) !
Thanks,
Ronnie
