That has a wonderful caudex Karyn. Very nice as you say for HD. We would never see any Adeniums here, atleast I never have. They would only come in here as a house plant and not a HH or H plant.
Almost looks like some kind of Coconut fibres in mix. Most peat moss used for retail purposes does not have long thread fibres.
Either way enjoy and what a wonderful find.
Will be nice to see when you have grafts on it.

Rick I haven't seen any at the HD's in the DC area either. As a matter of fact I've rarely seen anything remotely interesting at the local big box stores. That's why I was so surprised at how many nice plants they had at the HD in FL. Interestingly though the HD in West Palm had nice plants where the HD in Port St Lucie which is just an hour north of WP didn't. It's definitely not in coir. The fibers really aren't very long but might look that way because it's very dry.

Karyn, that was a steal....great buy.

Rick those stringy light colored things in the soil have me puzzled. Not sure what they are but they are very brittle, even when wet, almost like straw.

You know Karyn. It reminds me of a similar thing I have seen used, but as a mat of coarse fibres around bases of plants. Almost like the fibre wire basket liners I see here in spring for people to use for their annual basket.
In replacement of moss.
Anyhow, you had better make some more trips to that HD when you are there next time.
Like maybe the end of this month???
Hope you have a marvelous time at the horticulture show in Florida.

Karyn, you will just have to refrain from posting pics like this! I am amazed at the plants you all keep on finding, it's just not fair, so stoppit!!
Seriously, it's a great looking find and I will be very surprised if there is not more caudex going on down below. Let us see it when you re-pot please? What am I saying?!
