Any help would be absolutely appreciated! Would really like to know what they are so I can care for them better,
Here is a link that might be useful: Pictures.......
You may want to ask on the houseplant forum. Are you able to take closer pics of the leaves?
My guess is warneckii and marginata, respectively
Maybe massangeana and marginata.
I have one looks like yours --its warneckii or lemon/lime draceana-- just bought it last week of course it is much smaller than yours it was on the sale table at Lowe's and was very very pot bound--so it has a new home in a larger pot and I hope he grows up to be as big as yours--thanks and good luck
The second plant is D. marginata..Green. It needs a little more light.
The first plant would be a true beauty with proper light, soil and watering. I never saw a Dracaena such as yours. It's quite unusual. Toni
