Fantastic Evergreen Climber


This is a great evergreen climber that has lovely flat white flowers. It self clings to a wall or fence but may need support to start with. Great fro semi shade.




Bought for a London walled garden


Excellent for a shaded side of a city walled garden. Takes time to grow as all shrubs do but will look really good.

Would this be suitable for growing in a container up a wall? If so what pot dimensions would be best?


This climber is really too large for a pot, so it will be much happier if planted in the ground.


Hi, is this a true evergreen as I've seen various articles saying they are deciduous whilst some say they are evergreen. I would be planting in a shaded corner against a NW facing wall. Thanks James


Hello, These are mainly evergreen, but they can sometimes lose some of their leaves in the winter if they are badly scorched by a frost (they are not fully hardy), or occasionally younger plants may shed some of their leaves in winter.


Hi, will this plant do OK in a large pot? Will I need to give it any extra care? The spot I want to give it is a sheltered corner and only gets diret sun from late afternoon. Many thanks


Hello there I wouldn't recommend this large climber for a container, really it would be better grown in the ground.

I planted two of these about 3 years ago. They didn't look very healthy to begin with and I nearly dug them up but this year they have really taken off. They have flowered for the past 2 years but now that we are in mid-September naturally the flowers have died back on the stem. Do I need to deadhead them and if so do I take off the whole stem or just the flower head? I can't remember what I did last year !!! Many thanks.

Always trying

Hello there No you wouldn't normally deadhead this large climbing plant.

Hi, planted Hydrangea seemanii last autumn, in a raised bed against fence, sunny but with partial shade. It has survived the winter however any growth on the original wood stems appears to be dying off now. There is however a lot of new shoots/growth coming up from the ground. Will this new growth eventually produce a climbing plant and if so how long will it take. Is there anything I can do to encourage it? Would be grateful for any advice. Thank you.


Hello, It sounds as though the plant has just about survived the winter, and yes these new shoots should go on to clamber upwards. Unfortunately though, these are not fast growing plants, particularly when they are young, so they can take a few years to get established. The only thing you can do is make sure they are kept well fed and watered, and apply a generous, insulating mulch around the roots in autumn.


what size pot would you recommend to form a permanent home for this type of shrub , please, say at the back of a flower border, against a 7feet wooden south facing fence which may , very occasionally, have to be maintained in good order.


Hello, This is a large climbing plant, so I would not recommend growing it in a pot for any length of time - it will be much happier planted out into the border.


Hello I'm looking for an evergreen climbing plant, that is hardy. We live in central Scotland on an exposed site. I was hoping to grow a plant up a west facing wall. Do you have any other options apart from the Hyrdrangea Seemanii? Thank you


Hello, The best option for you would be one of the Hederas as they are much tougher than this hydrangea - please click on the following link to go straight to them. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.4/vid.1616/


Hi there, If I grow this on the front of my house wll I need to provide wires for it to climb up initially, and will it cause damage to the brickwork? Thanks.


Hello there No this climber doesn't need support as it will attach itself by aerial roots. It is not as damaging to brick work as say an ivy can be, but it will stick to your brickwork and get under guttering over time if not controlled. Hope this helps

Hello, I have a relatively newly planted Hydrangea Semanii growing in my garden; I probably planted it early March. It has been fine and perfectly happy until the last few days when I have started to notice the leaves starting to wilt and getting worse. I can't see any signs of blight; it is growing next to a fence in the dappled shade of a cherry tree. What's going wrong? Could it be too much or too little water? I'd be grateful for any thoughts. Many thanks


Hello, I'm afraid I cannot say for sure what the cause is from your description, however it is possible that the wilting has been caused by either too much or too little water. As hydrangeas are quite thirsty plants, the most likely cause is a lack of water as the area at the base of a fence always tends to be dry. Hydrangeas are prone to several diseases though - some of them quite serious - so do keep a eye out for any signs.


Hydrangea seemani not flowering? I have a Hydrangea seemani which has grown over the last 3 years and looks healthy but has never flowered? Any ideas? Thanks Ellie

Hello, The most likely cause would be either not enough sun or a lack of nutrients. You can often give them a push by feeding with a high potash fertiliser like Tomorite. I hope this helps.


Hello Ellie, There are a number of reasons why plants don't flower including too much shade, not enough water or nutrients, or pruning at the wrong time of the year. It can also be caused by the plant putting on new root growth instead of focusing its energies on producing flowers. I am not really sure why yours has not produced buds, but you can often give them a bit of a push by feeding with a high potash fertiliser. I hope this helps. Helen Plant Doctor

Hydrangeas - which one to choose?

Hydrangeas come in many guises, but the blue and pink mopheads and lacecaps that flower in summer are generally forms of Hydrangea macrophylla, an Asian species that prefers lots of summer rainfall and drier winters. This can be tricky in drier gardens, b
