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:Hi, will a Viburnum Opulus attract wildlife and insects into my garden? If not, could you suggest another shrub that would be suitable at the back of a large banked border that would be good for wildlife?Asked on 8/26/2013 by Wikikki from Mid Wales
This is a beautiful shrub that will attract the butterflies and insects for the 'snowball' flowers, and it's lovely to look at too. There are lots of plants that will attract the wildlife and insects into the garden... if you click on the link below it will take you to shrubs that are particularly good at attracting the wildlife.

I'm thinking of buying a snowball tree to put in my front garden next to a magnolia. I understand that it attracts aphids. Will this affect my magnolia? Also if I buy one from crocus how long would it be before it flowers eg next year, 2 years etc? When would be the best time to plant it? Thank youAsked on 8/5/2013 by Bernie from Stourbridge
These plants tend to flower quite young, so given the right conditions, you may have flowers in the first year after planting.Answered on 8/12/2013 by Helen from Crocus
This is a beautiful shrub, but it can be prone to aphids which can spread to other plants. Best to keep the plant healthy, and try to encourage aphid predators like ladybirds, lacewings and hoverflies into your garden to eat them by planting nectar-rich flowering plants which attract them, such as buddleia, calendula, sedum, stocks, sweet William and wallflowers. Also you can buy lacewing and ladybird houses to encourage them into the garden.

Can you advise on garden care /pruning of a Snow ball tree. I have one in my garden it is roughly 6ft x 6ft in a border. I feel it is becoming too large for where it is. Can you confirm if I could prune it and when to reduce overall size please. Any suggestions would be appreciated.Asked on 2/9/2013 by Sooty 1
The best time to prune this is immediately after flowering in spring. Once the plant is established, you can remove one fifth of the stems (choosing the oldest or the weakest), cutting them right back to their base. If you want to reduce the height further, then you will risk not having flowers in the following year and ruin the overall shape of the bush. If you want to take more drastic action, then you can cut all the stems back to their bases in early spring.

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
