I was just thinking the same Poly. I am waiting for the RBWH to come into flower in the next couple of weeks. When it did last year my bees capped honey like it was going out of fashion. It was very tasty stuff too!!
I saw the first rosebay willowherb flowers open at the weekend Busybee. The pollen is the colour of snooker chalk.
I also saw the first lime tree flowers open today and if we get hot and humid weather that can be a major nectar flow.
My girls are loving my New Zealand flax at the moment and bringing in lots of beautiful bright orange pollen from it. If you live near gardens John it maybe this yours are bringing in? (Sorry, don't know how to do the quote thingy...!)
