Hi Joshua. Welcom to ATP and the addiction/obsession known as gardening.
I started ~ 1976 and grows tons of stuff from seed as well - 2 years ago I started over 2,000 plants in my basement.
Kudos on the Foxglove - very lovely. They can sometimes be hit or miss - looks like yours were hit. And they also can be so whacky - annual, biennial (usually), perennial. I love them and usually try to have a "tall" garden with them, hollyhocks, canterbury bells, et cetera.
On the Dahlias - I grow ~ 10 types and like the Kelvin Floodlight a lot. In 2014 I had one that turned out HUGE. Could see it from a block away and it really shined just at sundown.
And congrats on that Hibiscus - I know what it is like to wait that long. I have some Dierama and Dietes that I grew from seed 2 years ago and must over winter indoors. Hoping they bloom this year. And some Siberian Iris now in their 4th year. Growing bulbous plants from seed sometimes seems downright silly.
