The Tudor garden was of a good logical shape which stayed in fashion for some hundred and fifty years. It was a square enclosure held in by walls or hedges, sited in front of the house so that house and garden were in friendly unity and the garden could be admired from the front windows or the terrace. Inside the square there were usually two main alleys crossing in the centre (as in the old monastery gardens) where there would be an ornament such as a flower-bed or a fountain. There were other parallel alleys, some open and flanked by trained fruit-trees, others covered in by pleached trees to make shady tunnels. ('Pleached' means interlaced or intertwined.) Fruit-trees were widely used in the pleasure garden, for the range of flowering shrubs was still small. Vegetables and herbs were frequently to be found planted in these beds among the flowers. The alleys were gravelled, sanded, turfed or carpeted with scented herbs, and in the spaces between, there were square or oblong flower-beds.
