Below is a list of plants that began to bloom in my garden in Seattle in April  2011. I recorded the date when the 1st flower opened, not when they were in bud. I think this information is helpful in planning your garden. If you need more plants that bloom in April, you can choose some from the list.  This can help you to combine flower colors.  Nurseries in Seattle usually sell plants when they are in bloom. I have included dates from previous years. Weather conditions probably account for most of the difference in bloom times.  April 2011 set a record, at 52.2F/11.2C, for the lowest average-daily-high-temperature since record-keeping began in 1891.  The average average-daily-high-temperature for April is 58.2F/14.5C.  April 2011 was also more rainy that usual.  In marked contrast, April 2010 was quite warm.
