This is the bloom of Medicago arborea which according to Wikepedia is called moon trefoil and, I think, μηδική δενδρώδης in Greek.  I grew mine from several cuttings clipped four or five years ago, potted and then planted the following year in the experimental bed near the garden gate.  It blooms from February to May.

It's probably obvious that I'm starting this blog by concentrating on individual plants not describing the garden and its design overall which might seem like the more obvious place to start.  I'm doing this for several reasons.  

The first is that this is the season of most intense activity in terms of the plants themselves many of which only bloom for a short time in spring and I want to record them before it's too late (or, in the case of gardening, waiting until next year).  I also spend a tremendous amount of time working in the garden at this time of year for the same reason, weeding, weed whacking, planting and transplanting, pruning, etc. which leaves me little opportunity to conceptualize the blog!

Second, I'm new to blogging and to photographing plants and it is easier to concentrate on individual plants on both levels.  I find the blog templates and formats inflexible, inconsistent and unpredictable and I hope that with use and familiarity I'll be able to develop an overall organization for the blog.

Lastly, the organization of the blog reflects my approach to the garden in general.  As a person who lived in apartments until I moved here, I started working on the garden, timidly, on a plant by plant basis rather than with an overall plan.  I made several major mistakes as a result (more on those later) but it is certain that the current state of things reflects this approach and that I am only now starting to proceed with an overall idea of where I'd like to see the garden go.

That being said, the photo below shows a more general view of the experimental bed (I'll explain why I call it that later) with the moon trefoil in the foreground and extending to the large myrtle bush in the upper right hand corner of the photo.  i recently planted a row of mulberry trees extending the full 20 meter length of the bed and some of the plants described previously can also be seen.  

One of my favorite plants in the experimental bed is another that is referred to locally as a βιολέτα (Nodding Stock in English no less and Malcomia flexuosa scientifically) which i started importing from the shore near the town of Thermi where it grows in abundance in many cases in the dry seaweed and blooms in March and April.  

In this case it's worth showing how it appears in its natural environment since it's my hope that at some point it will reproduce the effect here.
