Plant ID and can they be relocated?

[Spikeyplants]

I'm well aware there are weeds and mess all over, but this is a house we rent out. We are planning an extension and I'd like to know what the spiky and purple plants are, and whether they'd have any chance if we planted them elsewhere? The larger spiky plant has a lovely flower spike coming up in Aug/Sep each year.

Photo?

Definitely need a photo - could be several things.

Oh dear- yes, a bloody photo would have helped a great deal!!!

They’re Cordylines and are pretty tough. The weeds are bindweed, really difficult to get rid of. I wouldn’t normally suggest this, but if it will be under the extension foundation you could put weed killer down first.

Someone I know tried to chop down a large Cordyline, but left a bit of root and it grew again. So even if they look dead after moving they will probably sprout again.

@Beebumble2- thanks. Do cordylines transplant well? DH is keen to rehome them if possible. The purple one is fairly soft and nice, but the others are like razors! I'm not even sure how we'd get them out without being cut to bits!?!?

I’ve only ever repotted them, but you’ve nothing to lose by replanting them, as long as they’ve got enough water.

I think the green one is a yucca - spiky leaves and can get huge. No idea about transplanting them though, sorry.
