Adrasta needs a dry winter rest to bloom. As in completely dry. Back in Oct you stop all watering. The leaves will slowly brown and drop, which they're supposed to. Come Feb when a new growth first appears you begin watering, and the buds will form at the bracts where the leaves were. Mine is just starting new growth and tiny bud formation. That's when you resume watering and fertilizing.
You may be off the cycle for a bloom this year. But try stopping all watering and see if it starts to lose leaves. It's tough to ignore it like that, you reall want to water it, but that's what it wants! I'll post a photo of mine here when I get a chance - don't have time now, though.
