The Russian River Rose Company in Healdsburg is again offering rose harvest tours this year from April 12 to May 29. I posted last year about my experience on the tour. It really is a lovely way to spend the day--up to your neck in fragrant fields watching fat bees gettin' busy on a smorgasbord of roses while you fill your basket with blooms. Then there are tea and goodies to sample, roses to buy, and as long as you're in the neighborhood, why not stop by a winery or two on the way home. If you're in the vicinity, I highly recommend the tour.
As an aside, the climbing rose I bought there last year (called Rachel's Smile) has established itself well and is in bud!
