In the middle of April this year I planted a couple of Virginia Creepers to climb over the large stump left when the Leylandii was cut down. You might just be able to make out the dead looking stems in this blurry cropped photo taken just after they were planted. The arrows point to the top of each plant.
I wondered how long it would take for them to get established, maybe years.
I needn't have worried. Here they are this month.
I kept them well watered as they started to grow and the ground they are in is rich in a deep layer of decaying needles dropped over decades by the Leylandii. They are positioned so the base of the plants are sheltered from cold northerly or east winds. At this rate of growth by Autumn next year I should be able to watch a lovely display as the leaves turn from green to red.
