One big advantage of growing (especially hardy perennials) from seed is that you can find out what will flourish in the conditions of you own particular garden. It can be expensive to buy nursery-grown plants and shrubs only to find they struggle or die on you. At least two thirds of all the perennials in my garden were grown from seed. I had a lot of failures along the way but those which survive are healthy and perfectly established.
As others mention, growing from seed is exciting and the sense of achievement of watching tiny things you can hardly see turn into beautiful (and sometimes huge) plants, shrubs and trees is very rewarding.
