I want to order some seeds for some unusual container groupings for this summer. So many of the seeds shown are the average plants. What seed company could I order from that wouldn't cost me an arm an a leg--for instance $3.95 for about 15 seeds. I like plants that have unusual foliage and that stay nice all summer. I do some in-between plantings==for instance when the wave petunias get nasty looking--to keep them looking nice. I would like to winter sow them a little later. Thanks for your help - Barb
