this shrub fills huge areas in Crete. It is very thorny, impermeable by any animal - and very hard to prune, as I find. It is full of lovely yellow flowers in April. Do you agree with this ID?? Yes, No, Maybe??
I can get seeds this month if anyone wants to give it a try.
Your photo is amazingly like the plate #60 of Flowers of the Mediterranean (by Oleg Polunin and Anthony Huxley.) So your identification is correct but you should first discover if this particular Broom is listed as an undesireable alien in the US and other countries. In California we already have weed problems with Cytisus spp., especially C. scoparius, Scottish Broom. We are also plagued along the shoreline with Gorse, Ulex europaeus, which is so thorny as to be impenetrable by man or animal -- but lovely yellow pea flowers like in your photo.
As a matter of fact, it could be ulex as well...
It is really impenetrable, and very difficult to "train"
As for the USA, my intension is without target to a specific country - I know most people in DG are in the USA but not necessarily all, that's why I put the proposition for seeds so mildly..
Finally, several plants have been declared or are known as several things in several places, but still the seed trade continues, (like datura and ipomoea) so here I am.
Best wishes to you all.
If interested in more pictures of the same plant, just say it, I have taken several because the particular yellow is very bright.
Dimitri, is it a clear yellow or a bit muddy? The flower form does remind me of the Brooms here but they are not thorny. It sounds like it might be perfect along the far back fenceline to keep the cattle from pushing on the fence!
It will keep anything away from the fence. It is not the Brooms (I think you mean spartium - check in google). As marshseed mentioned, I am not aware of restrictions for plants in the USA, so if you check it you will make us both happier. I will work on a few other images I have tonight, and post them in plantID forum.
The yellow is light, uniform and very bright.
