Although I haven't ordered from this site, I've heard great things about the quality:

Diane's Flower Seeds

This will be my first year with hollyhocks, both perennial and biennial. Hoping to have much success.

Woops, guess I should have visited the site first. She only offers one type of hollyhock.

Here is my second try:

Swallowtail Seeds

I KNOW for sure they have tons of seeds!

I'm not sure what you mean by perennial hollyhocks...maybe some malva? I've grown them all, and the biennial kinds are by far the most enchanting, especially the old fashioned single type. In my garden the plants come back and flower for two seasons sometimes. The malvas and lavateras are lovely, but with shorter plants and smaller flowers...not as impressive, and some can be rangy looking and/or short-lived. Try them all and decide what you like.

I have grown various hollyhocks from seed, my problem seems to be getting rid of them - they reseed freely. Hollyhock "Antwerp" is supposed to be rust-resistant, I'm cultivating/planting those lately, because rust is the one problem I do have with these lovely, towering flowers.

I wintersowed Malvas and the regular hollyhocks. The down side for me was japanese beatles and runt. The rus didn't affect my malvas but they did affect the regulars. I finally gave up and am not going to fool with them anymore. They need an airy open area to grow with less chance of rust and I just don't have that kind of environment. My malvas were grown in clumps which gave the appearance of bushier plants. They also got about 5 ft. tall and loaded with blooms but once the Jap. beatles arrives I ended up pulling them out along with the regular hollyhocks.
