help with ID

Can anyone help with ID of those lovely plants?

 

Yucca!

 

Looks like Cordyline australis. Common name cabbage tree.

Going agree with both but say the front row looks like Yucca guatemalensis 'Variegata' and the back row Cordyline australis.

 

The cordylines are a purple form. The typical plant is green.

 

I think they are both cordylines. Used a lot here for dry garden plantings. I doubt they would have a yucca right on the edge. Too dangerous.

Hence the use of Y. guatemalensis(formerly Y. elephantipes,), the spineless Yucca.

 

Yes: there are many kinds of yucca.

 

I'm not too good with id'ing plants, but they look a lot like yucca's to me, similar to the ones I saw at a local nursery here.

 

Thanks All!
The Yucca (as on attached photo) has yellowish stripes on leaves.
Indeed leaves are very spiky.

 

Could be a variegated form of Y. aloifolia or Yucca gloriosa 'Variegata' which both have sharp spine tips.

 

Then it must be Yucca gloriosa 'Variegata' [It has spikes of white flowers](http://www.floridata.com/ref/Y/yucc_alo.cfm)
