Yucca species ?- Gangtok


A recent visit to Gangtok, Sikkim: this lily like plant noticed at one of the gardens.
Could not figure out what it is.
May be an Iris?
you have not provided the following:
height/length of the longest leaf
leaves pointed and sharp or not
leaves markedly succulent and not easily bendable or not
midrib vein thick or not...
these are pointers gardeners often can easily ascertain...

we have two obvious choices...
if its stiff and leathery leaf with perhaps a sharp pint its a YUCCA..
but relatively malleable, smoother to touch and thinner leaf blade its Coryline.
in yucca there are plants called 'yucca colorguard' in the nursery lingo.
and if its cordyline its most likely a a Cordyline australis which comes in various colors ...

This is why some details need to be to be noted when you are curious about a plant
