Each note uses a different letter name (apart from the blue note, which shares a letter with the fifth), so the spelling follows the scale rather than the keyboard: A C D E♭ E G.

A Blues scale formula

The pattern of steps from one note to the next is W+H – W – H – H – W+H – W (W = whole step, H = half step, W+H = a step of three semitones). Compared with the major scale the degrees are 1 ♭3 4 ♭5 5 ♭7.
