Garden Plants in Flower May - Trees, Shrubs and Bulbs | Flowers and Colour

May is the month in the garden when it all comes together. Shrubs are starting to be their best, the perennials are breaking cover and the yellows of the Daffodils give way to the more vibrant colours of the Tulips. Or have I got it wrong as I write this in January?

Certainly my own photographic and mental records would agree, but I am constantly being surprised at what happens in the garden.

This is where you all come in - PLEASE! I want to know what is flowering in your garden and when. Your input will take this Flowertime Project further than I could possibly do.

So what is in flower in the various parts of the country/world. Let us have your observations - either with botanical names - or common names with descriptions, and we will add it to this growing list of plants in flower, in the month of May. (This should be a big one! No matter we have plenty of pages waiting.)
