Hi Zen,
The first 3 pics look like Dracaena plants to me. The first one maybe Dracaena deremensis compacta. I don't know about the last one.

Hope that helps.

Elsie

Thanks Elsie. I'm wondering if maybe the tree-like one is a corn plant?

Zen, the bottom pic is Dracaeana compacta, 'Pineapple.' As it matures, you'll see the resemblance to a pineapple. The tree-like is Dracaena Deremensis, 'Janet Craig.'

Zen, no Corn Plants in the group. Toni

Thanks Toni :)

Zen, you're welcome.
Your friend gave you a nice plant collection.

One thing I feel I must add..lol. Although the succulent in the glass is very, very pretty, be careful when watering. Since the glass hasn't any drainage, 'succulents will rot if soil is kept constantly wet,' be certain it's completely dry before adding more water.

I apologize if you've already given this thought and have a solution. Toni

Thanks for the advice, Toni. I have rocks in the bottom for drainage but I think I'm going to have bf drill a hole in the bottom for me. We've been able to repurpose many containers now that we have a diamond-tip drill bit. Best purchase we've made in a long time :)
