Outdoor vs. Indoors: Can they be planted in a sunroom?

[abodelook]

I have a very bright, glass-enclosed sunroom and I'm dying to have a gladiolus flower display inside. I was window shopping at the abodelook under the Green Collection and this made me start to think about whether or not I can exude a vibe of an indoor garden that is luxurious. Will they be needed to pollinate them when I am only planting them to beautify or would they be okay in a contained room?
