Seems no one is chiming in from NY - specifically NYC - so I thought I'd add a note.
Up to three weeks ago we had nothing. Then witch hazel bloomed..then the croci and a few narcissus came out.
This week we've had the cherry, crabapple and apricot trees bloom, though it's been rainy and cold so I don't see much bee activity on them.
Flowers: we still with crocus, daffodils and hyacinths. A few dandelions are starting to push up leaves and in sunny, sheltered areas, I saw a few small blooms. No other blooming weeds. The city tends to be an ecological wasteland and monoculture of non-native plantings, so I've had to feed syrup for quite a while the last two springs before my garden got up and running.
Last week the maple trees were budding out and today, I see that their flowers have opened; the oaks and plane tree buds are just starting to swell. No holly, privet or anything else I can see.
We tend to be a bit cooler here on the south side of Brooklyn than perhaps inland because of our proximity to the ocean and steady harbor breezes, and this winter's weather was unbelieveably snowy, wet and variable. Last weekend it was in the mid-50's then it dropped to the 30's. Even though the weather service says it's 47 degrees today, I see that the girls are out of the hive and flying around in the sun, but it's nippy - definitely still coat weather.
