Dublinbay,Star Trek Hostas
The other thread got so long, I decided to answer you here. YES! Dark Star is fine in a Star Trek Garden. I planted one a few years ago, supposedly for my husband, but I gave me a chance to buy more hostas!
If you really want to go crazy, there is also Enterprise, First Mate, Lunar Orbit, Little Aurora, Moongate Flying Saucer, Starboard Light, Stardust, Starship, Planet X.
Some Star Trek purists might disagree, but I got anything available at the time that had to do with space. There are probably more now.
