Viburnum opulus 'Roseum'
snowball tree (syn. Sterile)
- Position: full sun or partial shade
- Soil: moderately fertile, moist, well-drained soil
- Rate of growth: fast-growing
- Flowering period: May and June
- Flower colour: white or green-tinted white flowers
- Hardiness: fully hardy
In May and June the branches of this vigorous deciduous shrub are smothered with large, snowball-like clusters of white or green-tinted white flowers - hence its common name. With maple-like, fresh green leaves that become purple-tinted in autumn it's an excellent ornamental plant for a sunny shrub or mixed border with fertile, moist, well-drained soil.
- Garden care: After flowering prune established specimens, removing up to one in five of the oldest and weakest branches to the base. Apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant.

Q:Please could you advise as to whether it would be suitable in a heavy clay type soil? Thanks AngelaAsked on 8/25/2014 by Wills from West Sussex
These plants generally do quite well on clay soils, provided it does not remain waterlogged for any length of time.Answered on 8/27/2014 by helen from crocus
Q:Hi - I bought a Viburnum Opulus from you in early Spring, and it has flowered beautifully (thank you!). I just wanted to know whether I should deadhead it conventionally, or just gently pull off the dead flowers in order to protect any new growth?Asked on 6/9/2014 by lily1 from South London
I would not dead-head at all and let nature take its course as attractive red berries will follow on.Answered on 6/12/2014 by helen from crocus
Q:Hi, my snowball tree gets badly eaten by caterpillars in may. I've tried a grease band as thought they may have been from beetles, but no sucess. Any idea what they are and how to tackle?Asked on 6/4/2014 by planty from nottingham
I suspect the culprits are the larvae of the Viburnum Beetle, which lay their eggs in the bark of the stems. Because of this, the grease band will not be very successful, however to keep them under control you need to be vigilant and at the first signs of attack from the caterpillars, spray with a suitable insecticide such as Bayer Sprayday Greenfly Killer, Westland Resolva Bug Killer or Bayer Provado Ultimate Bug Killer. An organic option would be a spray containing pyrethrum.Answered on 6/5/2014 by helen from crocus
Q:Is it possible to keep this smaller with regular pruning? I notice that in other answers you've mentioned that it can grow to 5x5 metres but I really wouldn't want it any taller than 3 metres high and a couple wide.
Also, if it did get too big, would it take a harsh pruning?
I'm really keen to have one of these in the garden so am trying to find a way to make it work!
Thanks.Asked on 5/1/2014 by Bex from South Coast
It would be possible to cut it back, however this would affect the plants ability to flower. Therefore I would not really recommend it.Answered on 5/2/2014 by helen from crocus
Q:What's the average growth rate per year please?Asked on 4/7/2014 by candygirl from yorkshire
Unfortunately it is really difficult to say how fast a particular plant will grow as this will be determined by a number of external factors such as the available water, light and nutrients as well as aspect and soil type, but Viburnum opulus 'Roseum' is classed as fast growing.Answered on 4/8/2014 by Anonymous from crocus
Q:Specimen Ceanothus or another large bushy shrub....
Good afternoon, When I was first looking for a Ceanothus to replace the one we have in our front garden, I looked on your website, but you only had small ones. Our once lovely Ceanothus has been pruned out of all recognition again this year, as I planted it a bit too near our boundary when it was a baby. I know it may come back, but it is getting ridiculous as every time it grows back it has to be cut back again severely and then ooks a mess for most of the year. Have you got a nice, tall, bushy Ceanothus to replace it? I love my Ceanothus but perhaps if you don't have a big one, do you have another large, flowering shrub as an alternative? Hope you can help Regards MargaretAsked on 12/5/2009 by D DRAKETT
A:Hello Margaret, it is rare to find larger sized Ceanothus as they are usually quite short-lived and don't normally live longer than 6 - 8 years. We do have a selection of larger shrubs on our site like Hamamelis, Hydrangeas, Magnolias, Acer, Cornus, Cotinus, Philadelphus, Syringa and Viburnum, so you may find something of interest. They will be listed in this section. http://www.crocus.co.uk/plants/ I hope this helps. Helen Plant DoctorAnswered on 12/8/2009 by Crocus Helpdesk
Q:Viburnum opulus 'Roseum' (Snowball tree) size?
Dear Crocus, Would a Viburnum opulus 'Roseum' the Snowball tree be OK in the back of a 6 ft by 7ft bed? Also when is the best time to move plants? I would ideally like to change the bed around in Sept/October. Many thanks ChrisAsked on 7/20/2009 by CHRISTINE JONES
A:Hello Chris, This plants will eventually grow to 5 x 5m, so it will eventually outgrow the space, but it will take several years to get that large. As for moving things, the best time is in autumn or early spring when the plants are dormant. I hope this helps. Helen Plant DoctorAnswered on 7/21/2009 by Crocus Helpdesk
Q:Viburnham opulus 'Roseum' (snowball)
Please can you advise me as to whether this Viburnum opulus 'Roseum' would do well at the back of a large bed. Many thanks ChrisAsked on 7/12/2009 by CHRISTINE JONES
A:Hello Chris, If you have the space, then this will look great at the back of a mixed border as it will grow to around 5 x 5m.Answered on 7/13/2009 by Crocus Helpdesk
Wildlife-friendly gardens are not only more interesting as you can watch all the comings and goings, but they are often more productive as many creatures will help increase pollination. Garden ponds act as a magnet to dragonflies and damsel flies, along wRead full article
Why is it that the majority of gardens look their best during spring only to turn dull and lifeless for the rest of the year? It’s partly because spring is when most gardeners buy new plants and partly because too few people consider what the plants willRead full article
Many late-spring and early summer flowering viburnums have scented pink and white flowers held on spreading branches and these often perform with the main flush of tulips, either in April or May. Their strawberry and vanilla ice cream colouring provides aRead full article
