Cornus Venus ('Kn30-8') (PBR)
- Position: full sun
- Soil: fertile, humus-rich, well-drained, neutral to acid soil
- Rate of growth: average
- Flowering period: May to June
- Hardiness: fully hardy
Recently hybridised in the US by Dr. E Orton, this new dogwood is the result of crossing Cornus nuttallii and Cornus kousa var. chinensis. The result is a beautiful small tree that is very tough and undemanding, has good drought tolerance and a high resistance to diseases. Its most striking feature however is the size of its creamy white bracts, which appear for several weeks from mid to late May. These are extremely large and can grow up to 15cm across, which creates a spectacular show, especially as they are usually produced in large numbers once the plant has become established. On more mature plants, these 'flowers' may be followed by large, strawberry-like fruits. This tree has the added bonus of providing spectacular autumn colour, when the large, glossy green leaves take on rich shades of yellow, orange and purple. Its compact habit and many interesting features make it a stunning focal point in a smaller garden.
- Garden care: Incorporate a good amount of well-rotted leafmould when planting. Requires minimal pruning.

Q:Cornus kousa - my soil is not acidic, I would love to grow this (or Amelanchier) I assume that autumn leaf colour wouldn't be as good, but what about chlorosis?Asked on 27/4/2014 by Suzanne from Lincolnshire
These plants will grow in neutral to acidic soil, so as long as the pH is not alkaline you should be fine. As for the autumn colour, this is largely determined by the amount of sun the leaves have, so it should not be adversely affected by the soils pH.Answered on 30/4/2014 by helen from crocus
Q:I am looking for a small tree as a central feature in a courtyard and came across this cornus.
The photo on the website only shows the flower and leaves and not the overall shape of the plant.
Is this a multi stemmed shrub or can it be gorwn/ pruned to be single stemmed "tree"?
If you have a photo of the whole plant can you please send it to me?Asked on 5/2/2013 by Cheley from Bucks
These trees are naturally shrubby and often come with several stems or low branches. It is usually possible however to train them to have a short, clear stem by removing the lower branches as the tree grows.
I'm afraid we do not have more pictures of the plant, but if you do a search on google images it will show you the different ways it can be grown.
I hope this helps,Answered on 6/2/2013 by Helen from Crocus
Q:Cornus Kousa - when will it start to grow in the Spring?
I bought a Cornus Kousa from you last year. It is March now and at the moment it isn't showing much signs of life. Have the severe frosts etc. slowed down the growing process, and when can I expect it to start budding etc? Thank youAsked on 9/3/2010 by dorothy law
A:Hello There, It is still too early for most plants to be showing any signs of life and as we have had such a severe winter, everything is even slower than usual. I would not expect to see any signs of life on your Cornus for at least 6 - 8 weeks. I hope this helps. Helen Plant DoctorAnswered on 10/3/2010 by Crocus Helpdesk
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 5/12/2009 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 8/12/2009 by Crocus Helpdesk
Q:My Cornus has not flowered?
I have a dogwood - Cornus 'Eddies White Wonder' and it has not flowered. Can you tell me why?Asked on 8/7/2009 by B Homer
A:Hello There, It is not unusual for these plants to take a few years to settle in before they start to produce flowers so you may need a little patience - but once they start they are well worth the wait. You can help them along by making sure they get lots of sun, and feed them with a good general purpose fertilise during the growing season.Answered on 9/7/2009 by Crocus Helpdesk
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 17/3/2005 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 21/3/2005 by Crocus
