Q.Round Rock, TX Zone 8b Will Starfish Iris Grow Here In The Ground?
Would starfish iris grow outside in the ground in zone 8b or would they need to be in a container that would be brought inside in winter? (I am thinking of sending as a gift)

Starfish iris cannot take a freeze and are hardy in zones 9 to 11. You are right on the edge, so if you want to try to plant them in the ground, be sure they are mulched well and sited in a protected area, preferably on the south side.
They can easily be planted in pots and grown inside. No need to summer them outside because they are dormant in summer. Here is more:
