Cornus alba 'Sibirica'
- Position: full sun to part shade
- Soil: any moderately fertile soil
- Rate of growth: fast-growing
- Flowering period: May and June
- Hardiness: fully hardy
This deciduous shrub has oval, dark green leaves and produces small, creamy-white flowers in May and June. But it's really grown for the bright, coral-red stems that are revealed when the leaves fall. This lovely dogwood looks stunning planted in groups, beside water, or in a winter border. Best in full sun, it works particularly well with orange or purple-stemmed varieties of dogwood.
- Garden care: For best stem colour, cut new growth back hard to within 5-7cm (2-3in) from the ground in March and apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or horse manure around the base of the plant.

Q:I love the colour of Cornus Alba Sibirica and I want to know if I can plant it in the part of my garden that has little sun and in winter can become very wet also if it is suitable for my garden can I plant it in September? Thank you, Juie.Asked on 8/28/2013 by Julie, Cardiff from Cardiff
Cornus alba 'Siberica' will tolerate most soils but it won't like it if it is water logged. Also varieties like this that are grown for the spectacular stems colour best in full sun, so if there is little sun you won't get the best stem colour.

Q:Creating a Winter Garden
Dear Crocus I am wanting to create a " winter garden " area and fancy an Acer griseum as the central feature. I had thought of planting a Cornus Midwinter Fire and Bergenia 'Bressingham Ruby' to complement the scheme but I would welcome any other suggestions please. Many thanks ClaireAsked on 2/26/2010 by CLAIRE LAWTON
A:Hello Claire, If you click on the following link it will take you to all our winter flowering plants. I would definitely recommend hellebores and snowdrops, perhaps some Cyclamen and and Euonymus fortunei for foliage colour. http://www.crocus.co.uk/plants/_/vid.204/ I hope this helps.

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:Plant help with Camellia pruning, bugs on our Acer, Cornus not growing and our Philadelphus still not flowering!
I have some queries regarding a few plants purchased from Crocus which I'm hoping you can help me with. This year we purchased "Camellia ?? williamsii 'Debbie'" and it seems to be growing nicely already, however it's very straggly, it arrived with two stems tied to a cane. The stems have continues to grow, and it's now tied to a longer cane, but it's showing no signs of bushing out. Will it do this with more time or do we need to start pruning to encourage it? We also bought "Cornus alba 'Sibirica'(red-barked dogwood)" and have it in a nice sunny position. It's lost its leaves for the winter and the stems are lovely, but it hasn't grown at all since we bought it (in June). Is this normal or do I need to do anything specific to help it along? We bought a Japanese Maple "(Acer palmatum var. dissectum Atropurpureum Group)" a few years ago but has recently become infested with some kind of beetle. We didn't notice anything, until we were moving the tub at the weekend and found the tree, soil and side of the pot coated in little grey/brown beetles slightly bigger than aphids. I've sprayed it with a pesticide which seems to have killed them, but I'm wondering what they were and what if anything can be done to ensure they don't come back, preferably without having to keep coating it with pesticides. Finally, we also bought a Mock Orange (Philadelphus Manteau d'Hermine). We originally had it in a tub, where it grew at an enormous rate, but it had no flowers. This year it seemed to be pot-bound, so we transplanted it into the garden, in a nice sunny position. It has continued to grow in both width and height, but to date has still had no flowers. Any suggestions? Thanks MarkAsked on 10/21/2009 by Anonymous
A:Hello Mark, Young Camellias can be very variable in shape, and some pruning is often needed to encourage a balanced, bushy shape. If yours is long and thin, then you can encourage it to bush out by pinching out the growing tips and shorten over-long stems. Ideally this should be done in spring, after it has finished flowering but before the leaf buds break. As for the Cornus, it may simply be concentrating on putting on new root growth rather than top growth, or perhaps you have very heavy soil, which will slow growth down. You should not really be feeding many plants at this time of the year as you can do more harm than good by encouraging new growth at this time of the year. I would however expect to see some signs of growth in spring next year, at which point you can start feeding again. I am not really sure what insects you found on your Acer, but it may have been woodlice. These are completely harmless, but they do eat decaying organic matter such as leaves etc and they do like cool, damp spots to hide out in. Finally, 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. 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 during the growing season. I hope this helps.

Q:Which plants are Deer proof?
I want a list of Deer proof plants please. It`s either a change in habitat or environment, but I get total devastation now and in the last two years they come up the drive.Asked on 2/3/2006 by david
A:Deer can be a real problem and deer proof plants are usually thorny, poisonous or simply taste awful, but it is hard to give a definitive list as you might get the odd deer with unusual tastes which might like the bitter taste! Below is a list of good plants that generally are quite successful though. Cornus varieties, Rhus, Sophora, Solanum, Berberis, Rosemary, Buxus, Cotoneaster, Ilex, Pyracantha, Garrya, Juniperus, Nandina, Elaeagnus, Aralia, Aucuba, Cortaderia, Yucca, Santolina, Hypericum, Myrtle, Vinca, Achillea, Digitalis, Echinacea and Dryopteris. Finally, fencing is one method to protect garden crops from deer. Since deer jump, you need an 8-foot fence for best results or stout chicken-wire fencing securely around smaller garden plots. Alternatively, fence the area with a thorny shrub, preferably something that will grow to at least 6 feet. Deer eat roses and some thorns but hawthorn, boxwood and holly will exclude them. Deer are also deterred by dogs, hanging aluminum foil, mirrors, wood that hits objects in the wind and other noise-makers. Some old-fashioned repellents are human hair and blood and bonemeal. Hanging bars of fragrant deodorant soap from branches may work. Other well-known deer repellents are mothballs or moth flakes spread on the ground or put in mesh bags for hanging in a tree. Unfortunately though, no repellent is 100 percent effective, especially if the deer population is high and deer are starving.Answered on 2/6/2006 by Crocus

Q:Can I prune my dogwood now?
I have a small Cornus florida that was planted in the Autumn. It is bushier than I would like as I want a tree rather than shrub. Its starting to bud now and I probably should have pruned it in the winter, but is it too late now?Asked on 3/17/2005 by Richard Stanaro
A:Ideally you should prune this Cornus in late winter or early spring. However you may still get away with it if you do it very soon. Just cut back the branches you don't want by pruning to an outward facing bud.Answered on 3/21/2005 by Crocus
