I have a Lewisia, Galaxy plant indoors that I grew from seed. It bloomed indoors but didn't set seed. Now it has a new flower stalk coming but the old one is still green. Should I cut it off? Is this normal for the plant? This is the first time I've ever gotten it to bloom (or even survive) so I'm completely at a loss. I hope to be able to plant it outdoors next year and want the biggest, healthiest plant possible. Should I even be letting it bloom?
