I think it takes 80-95 days from seed to flower. Since winter sowing will let the seeds germinate as the soil warms , it may not allow the seeds to be ready by May 30. I would try starting them inside with grow lights and a warming pad under them to get them started right away. Good luck with the wedding.

I agree with other posters that you should paint the coach light and its pole black. You might consider adding matching, wall-mounted coach lights to flank your front door and the garage door. You also might add white-painted window boxes and add real or artificial greenery, pine cones, and weather-proof ornaments in colors appropriate for certain holidays. For the fall season, you might use the pole to support a scarecrow dressed in autumn colors and then place three or four large pumpkins along the sidewalk. For winter, add a wreath with a red and green plaid bow to each door, window, and the yard light to celebrate Christmas. Later, you could suspend a string of small red or pastel-painted wooden hearts from the wreath on the pole for Valentine's Day and change out this string for a string of small green-painted wooden shamrocks for St. Patrick's Day and the spring season. For a bit of "punch," paint the trim around the garage door the same beautiful red as your front door. I do not know what your budget it, but it seems the house would look better with double windows on the right rather than the single window. Other posters' suggestions for evergreen plants and color are great, but some colorful, seasonal decorations could help with the curb appeal as well.

This past spring I opted to go WILD due to the late spring. I purchased a bag of wild flowers, some of which were perennials. Does dead heading also apply to these splendid flowers? Will they bloom next year?? It seems that they also attract little yellow birds and a host of bees and butterflies. I would love to see them reappear next season.

Along with their growing habit, I much prefer the shinier leaves on ivy geranium. At our previous home we had a 9-foot window box across the front of the house. It was always full of white, pink and blue Blizzard ivy geranium...gorgeous. Our new home doesn't have window boxes, so I have them in urns and a brick planter in front.
