Thanks so much, Tim.  Bert and I designed the garden ourselves.  It was all weeds and sand when we bought this property and we have worked hard to improve the soil.  We were fortunate to have a number of large trees which created the bones of the garden.  I am more of a landscaper than a collector, so we group some of the same when we can get enough of them.  Unfortunately, that doesn't happen often, because up here I can get only Mammey and Petra, so I'm limited to what I can get when I come down there for the sales or the auctions.  I haven't been into crotons long enough to have plants large enough to air layer, so it takes time, so I just keep collecting!  I love all plant groups, so I try to grow whatever I find that I like.  Again, I am limited by what I can find up here.  I would have a great time if I lived in South Florida!
