Clematis armandii 'Snowdrift'
clematis (group 1)
This spider-flowered, starry white clematis has cool-green anthers which pick up the colour of the narrow high-gloss leaves
- Position: full sun or partial shade
- Soil: fertile, well-drained soil
- Rate of growth: fast-growing
- Flowering period: March to April
- Flower colour: white
- Other features: evergreen
- Hardiness: frost hardy (needs winter protection)
This vigorous, evergreen clematis produces a profusion of sweetly scented, star-shaped pure white flowers from March to April. It is perfect for a sunny west or south-facing site, sheltered from cold winds. The glossy mid-green leaves are retained throughout the year, making it an excellent climber for clothing an unsightly wall. Please be aware that this plant is toxic to dogs if eaten.
- Garden care: No routine pruning is necessary. If the spread of the plant needs to be restricted prune immediately after flowering, cutting back overlong shoots to healthy buds. Apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the base of the plant in early spring.

Q:Is it possible to grow Clematis armandii in a pot, if so what size pot do you recommend?
I want to cover a small trellis (3ft x 6ft) that has a concrete base under it.Asked on 31/1/2015 by del from Cheltenham
This isn't the best clematis for a container as it can grow quite large and your trellis won't be large enough for it. However there are some compact climbers that could be grown in a container. I have attached a few links below.
Hope this helps.Answered on 2/2/2015 by Anonymous from crocus
Q:I have a clematis armandii climbing over one side of a wooden rose arch could you recommend a rose that would go well with for the other side pleaseAsked on 15/4/2013 by Tot from Ewhurst surrey
Unless you have a particularly large rose arch, I would be reluctant to put anything on the other side as the Clematis alone will grow to 3m in height.
If however you are confident that you have enough room, then I would be tempted to grow something with a later flowering period as this will help extend the period of interest.
Clemnatis Alba Luxuriens has a long flowering period and will continue with the white-flowered theme. Please click on the following link to go straight to it.

Q:Advice on climbers please
Hi, I need to find climbing plants for the length of a 2m high wood panel fence with concrete posts. I haven't measured the entire length but I would estimate around 15m. It is South facing and on a side of the garden that gets a lot of sun in the summer, the soil is clay and tends to dry out. I have no idea how many plants I would need to cover the entire fence (I am notoriously bad at judging the spread of a plant and always end up with an overcrowding problem). I am looking for something to deter anyone from climbing over the fence, yet ideally something that won't be treacherous to deal with myself (if such a plant exists!). Climbing roses are the first to spring to mind and if I were to go down that route I would definitely opt for white or cream flowers. I have had a look at the white climbing roses on your site but am unsure whether they will be happy in our soil, as you specify 'moist, well-drained' humus rich soil. I would also like to get an evergreen climber for the rear fence (+/- 5m long). I am not concerned whether this flowers or not, and I am less concerned about this being a 'thief-deterrent'. The soil is the same,- lots of clay, which plants seem to like, but it is very hard to work with and dries out easily in the summer. Any advice gratefully accepted! Best regards, HeatherAsked on 12/3/2010 by Thuli
A:Hello Heather, Unfortunately there are no plants that will deter intruders without being difficult to deal with, and the best plants are those with thorns like the roses. It sounds like roses will certainly grow in your soil, but ideally you should dig in lots of composted organic matter and then make sure they are kept well watered in summer. It can be difficult to see a small plant and imagine how big it will grow to eventually, however we do give all this information on each plant card, which hopefully should help. You will find it just to the right of the pictures at the top of the pages. If you click on the following rose, you will see it has an eventual height and spread of 10 x 6 m http://www.crocus.co.uk/plants/_/roses/climber-rose/rambling-roses/climbers/rosa-filipes-kiftsgate/classid.1280/ while this one will only grow to 3 x 2m http://www.crocus.co.uk/plants/_/roses/climber-rose/climbers/climbing-roses/rosa-climbing-iceberg/classid.1181/ I would pick the one you like the look of and then you will be able to establish how many you need to fill your fence. As for the evergreens, if you click on the following link it will take you to our full range of evergreen or semi-evergreen climbers that will grow in clay soils, but the same rules apply re preparing the soil and watering. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.9/vid.228/ I hope this helps.

Q:Climber for South facing wall
Dear Sir/ Madam, I wanted to order a couple of climbers for a south facing wall. I already have a Virginia Creeper growing but the wall is concrete and looks terrible in the in winter. Have you got any recommendations for an evergreen climber that would grow well on a south facing wall, and also grow with a Virginia Creeper? Kind regards, RolandAsked on 10/12/2009 by s8films
A:Hello Roland, The best will be the Hederas, which are self-clinging like the Parthenocissus - just click on the link below to go straight to them. http://www.crocus.co.uk/search/_/search.hedera/ If however you can put up a network of wires or trellis, then you can choose from any of the following. http://www.crocus.co.uk/plants/_/climbers/plcid.15/vid.228/ I hope this helps.

Hi, Just a quick query regards Clematis montana var. rubens 'Pink Perfection', is this an evergreen species or is there a variant that is? Many thanks, Regards, ShaunAsked on 20/11/2009 by Anonymous

Q:Clematis armandii toxicity
I understand that all the varieties of Clematis armandii are toxic to dogs. Does this mean toxic if eaten, if touched, or if smelled, and how severe is the toxicity? I have a dog and would not wish to endanger his health. DavidAsked on 10/7/2009 by D M
A:Hello David, It is difficult to determine exactly how toxic a particular plant is as some animals will have a different reaction to others. I would have thought that it would be poisonous if it was eaten, but I'm afraid all the toxicity information on our site refers to how it affects humans. I do not have information on plants which are toxic to dogs, but perhaps this is something your vet could help you with. I'm really sorry not to be more help.Answered on 13/7/2009 by Crocus Helpdesk
Q:Should I trim my Clematis armandii?
I've recently planted a Clematis armandii and while one shoot is doing splendidly and clambering up the trellis, the others are sort of just sitting there and staring in wonder at it. My instinct is to pinch off the top of the growing shoot in the hope that the others will then leap forward, but am a bit worried this will simply stop all growth. Could you please advise? Also if you are feeling particularly helpful could you tell me whether it has a scented flower?Asked on 27/4/2005 by Annie W-Noble
A:Trimming back the vigorous shoot will encourage the plant to produce side shoots, so yes I would recommend doing this. Also the Clematis armandii do have almond-scented flowers.Answered on 28/4/2005 by Crocus
