Here in southern California our traditional safe tomato planting date is March 15. Some years we have no frost at all, but I have known really killing frosts as late as April 22. Do you have a greenhouse? Go ahead and plant the start from David. If that doesn't survive, let me know in May and I'll replace it then. But remember, this is a tropical plant. It is not likely to survive your zone 7 Baltimore winters outdoors--even if they are considerably warmer than this year. John C. MacGregor South Pasadena, CA USDA Zone 9 Sunset Zones 21/23
