We all have our preferences, Trish. I take cuttings from mine in fall, start new plants to over winter inside under lights. In spring I take cuttings from those... and I add a few new ones each year.
Re: seeds: Coleus are slow growing from seeds, but easy to do. I've not found them to be very tolerant of sun, even here in Ohio. The Versa series are supposed to be sun tolerant but for me they fried in sun. Beautiful in shade, though.
The vegetatively propagated ones a far better for me. They're very slow to bloom or set seed. Many are sun tolerant. Rosy Dawn has wonderful plants and a great website, a good source for information on which are sun tolerant.

Note, Vegetative ones are solely propagated from cuttings- i.e. it doesn't mean cuttings from seed grown plants, they are different strains altogether.
