Foxglove and Delphinium

Is it too late to grow these from seed in Columbus Ohio (zone 5)? If not, will they be ready for fall? And why am I confused by the "biennial" label the seed packets have on them?

You can grow the foxglove from seed but it won't flower this year. It will flower next year, on a 2-year cycle, which is what makes it a biennial. The delphinium you speak of: is it larkspur? That's an annual that has been called delphinium in the past. Its Latin name is Consolida ajacis. The seeds need a cold treatment (such as overwintering) to induce flowering.
