This is Dactylorhiza - terrestial orchid, perennial that belongs to the orchid family, under protection. Finding it growing in the backyard's wet meadow was so surprising. They grow up to 30 cm (12 in). I am not sure, but it seems to be Dactylorhiza maculata - have to turn back and take a closer look.
Have a closer look at the house. Can you see what I see? This house in fact is two houses joint together with and an open space. First house is on the left side, second on the right side. 2 old wooden houses brought from eastern part of Poland - they were disassambled there and constructed together bit by bit again.
This is the left side house - yes, it used to be one/full house. While on the right side you can see the part that joints both houses together.
Virginia creeper (Parthenocissus quinquefolia) covers partially the house from the western side.
Safe wood reserve for colder days...
