Answer: Often a seed packet will tell you how long it takes from sowing seeds to first bloom. For instance, sweet alyssum averages 56-63 days. However, days to maturity are just a guideline, because so many factors can influence the growth rate. I recommend sowing several sets a week apart to make sure you aren't disappointed. Some wildflowers are challenging to germinate and grow, so I'd stick with the alyssum. If you have a greenhouse you can use, you may be able to persuade violas or ageratum to be in bloom in time for the wedding. And my final advice is to have a backup plan for favors in case the plants don't grow as expected. Best of luck!
