Why did some of the hollyhocks I grew from seed last produce only leaves and about 1/2 the plants I grew from seed only produced flowers? The ones I planted in my garden produced lots of leaves.

If the ones you planted in the garden were the only ones that did not bloom, then either the location you planted it did not have enough light or the soil was too high in nitrogen or too low in phosphorous. All of these things can affect blooming.
