This has been one late rose growing season in Western Washington. Last year my first bloom was April 20, 2016 and this year we are at least three weeks past that date and my garden is seeing a lot of very tight buds and blind shoots. I went out during a brief dry period to capture a few images to help you understand. Paul Zimmerman wrote the following for Fine Gardening magazine: A blind shoot is a stem that grows and grows but a flower never appears at the end of it. There are a few reasons why this happens. The most common one is a late frost in spring that kills the tiny rose buds before they can fully form. Other causes can be lack of nutrients, shortage of light and tiny midges.
In my garden It could have been late frost or shortage of light this spring. We have broken many records for excess rainfall/lack of sunshine. The rose variety in the photos is ‘Whirlaway’.
