What is this? Yucca? Cordyline?

[Colin1110082]

Z6B Connecticut, there are these large trunking yucca looking things in pots and they’re out all year around. This area has gotten deep freezes and gotten into the mid 20s yet they are still standing. What could these be? I’ve also seen a large one in my town, which is 6A, I even first thought it was a potted yucca rostrata. If someone could ID it I’ll get one for my yard

Im not sure if that’s it, wouldn’t a Draceana be mush by now? They have gotten mid 20s and some freezes.

It's D. marginata,  Note how the base of the leaves attach to the stems / trunks a bit differently than the  Yucca sps below:


Y. gloriosa  cultivar..





Y.  pallida









Y. baccata










Y. rostrata








Y. elephantipes / gigantea






D. marginata can tolerate some cold, ..Grown outdoors across many areas in California  inc some areas of the state where it can dip below freezing.

If the pictured potted marginata is sitting under a covered porch, that may be how it has escaped damage..

It’s out in the open 🤔 It says hardiness zone 10 when I looked it up

Digging around a little more due to a nagging suspicion,  i'm also scratching my head a little on this one..  Thinner leaves scream Dracaena marginata  to my eye  ...compared to Cordyline australis  ( Leaves are typically wider ..Sold hundreds of each in the past so   ..you get used to the subtle differences some might not notice between them when you see them side by side every day, 345 days / year, lol  ) ..It is much hardier ( somewhere in the low 20s / teens )  compared to D. marginata..  ..And pretty common in landscapes in Cali.
 

So,  ..definitely can't rule out it being a C. australis  cultivar because i also wouldn't think the other would have survived outside when exposed to repeated episodes of the temps. you described,   ...even if D. marginata  can tolerate a little more cold  than what some internet - based sources might suggest.

A cordy line seems more realistic than D. marginata. It could be one of those

From my point of view Cordyline australis, looks like the one im my garden. It's freezing back when temps drop down to -8°C/18°F but recovers in spring.
