Parthenocissus henryana: how much shade is too much?
| | |

| Hi. I have a young Parthenocissus henryana, currently with growth to about a foot, that I want to grow against the back wall of my house. The wall is north-west facing. The only area of ground that I can plant it into is in the corner of the house wall and a high, north-east facing fence, with additional overhead shade cast by a tall, deciduous shrub. It is only this corner that is very dark; once the vine climbs a few feet higher and starts to spread, it will get adequate light. What I’m concerned about is whether, in such conditions, it will actually put on enough growth to get it up the wall and into more favourable conditions. I don’t want to plant it permanently in a container, as it’s such a vigorous plant. I could possibly keep it in a pot until it’s bigger and train it to the wall then, but as it’s a self-clinging climber, I don’t know quite how that would work. Can anybody advise? Many thanks. |

| Can there be too much shade for this? I don't think so. If it is too dark, the first thing it will do is put forth long growth until it finds light. If think it is a win-win. The other thing I've found is they won't take off until the get their roots into the ground, then it will surprise you. |

| I planted two in the middle of four towering walls, of which the sun facing two were at least two stories high. That was ten years ago. They are all covered now by the plant. I think it climbed at least 12-15 meters to find sunlight. |

| Thanks to both of you for your encouraging replies. I feel confident now to go ahead and plant it out. |

| Mine reaches the top of my four storey house every year and has to be regularly trimmed. The pale colouring of the leaf veins in the growing season is better in the shade but the red Autumn colour is better in the sun. It is growing in a tiny hole beteen paving slabs on a N facing wall but reaches a W facing wall after one storey. Goodness knows where it gets its nourishment from. |
