- This week on The Horti-Culturalists we take a look at another of Stephen's national collections for Plant Trust, the flowering dogwoods, or Cornus. We're looking exclusively at the North American species in this video as they're all in bloom at the moment but we'll look at dogwoods from other regions when they are in bloom later in the season. In this video we cover basic care and talk about Dogwood anthracnose disease which has found it's way into Australia.
The plants we're looking at in this video are:
Cornus nuttallii - the Pacific dogwood
Cornus 'Eddie's White Wonder'
Cornus florida - the flowering dogwood
Cornus florida 'Rubra'
Cornus florida 'Pluribracteata'

Stephen's other national collections are Sambucus and you can see our video about them here: • Sambucus genus profile...
And Acanthus and we look at one particularly rare one here: • Plant Profile: Acanthu...

Never stop making videos guys. We watch you both every week and love all your content.
Thank you very much!
I have not learned this much about a type of plant in ages! Thank you so much. You've essentially given us a crash course; whereas other programming just never offer enough to satisfy all our questions. And you've made it fun - I think the banter between 2 enthusiasts is what makes it work. Thank you. Your youtube endeavors are greatly appreciated.
Thank you very much - that was our aim!
I am looking out at my dogwoods in the PNW USA in their glorious fall color! Growing up in Portland, OR these were a set and let it go plant. Since I moved into glacial tithe, mine struggled because we have such sandy, silty, rock soil a layer of compost about 6 inches deep making a new flowerbed at their dripline has really helped! I don't worry about anthracnose either. Lose a few branches, but it grows more.
This was so on point for me as i am planning to put in a dogwood next year and have been doing some research. Dogwood being the provincial flower of British Columbia.
Thanks for watching - glad it was useful!
Great information and sumptuous blooms. Thank you.
Thanks Rachel!
Now I'll have to go down to VanDusen to compare your dogwood to theirs! Pacific Dogwood is the provincial flower of my home province, British Columbia. In the spring, it's quite amazing to see them in the forest. Anthracnose is a real concern here. It's part of the reason why I chose a Japanese dogwood for my garden instead of the native variety. I look forward to your other dogwood videos!
Thanks for watching - do report back on the comparison!
@@thehorti-culturalists I'd best wait until our spring for a fair flight.
The double one is beautiful. How does it propagate naturally since it has no actual flower ? We have the single white dogwoods all over our area. We've moved a few from the hedgerow to our yard.
It doesn’t propagate and can only be grown by cuttings so wouldn’t survive in the wild, Regards Stephen
Hello and nice to see you two. I want to know if you ever deal with oleander gall disease?
Also some umbellifers trees shape hardiness to zone 7 and a lot more.
BTW cornus mas fruit are very healthy
Sorry but I don’t grow Oleander and have no first hand experience of the gall. I assume you are looking for spreading shade trees. Can I suggest that local nurseries would be the best bet as it’s not just about what will work but also what is available. Regards Stephen
Thank you for the reply. Regarding the trees I've noticed some cedrus atlantica, mature ones having the shape that makes you imagine something like savanas, or those geologic periods depicted in atlas. I like the shape of the design, not really looking for the shade
This is such a great channel!
Thanks for finding us!
Love all of your videos.
I have a pink Floracion de cornejo Pink that I want to put in my landscape near my house.
how far should I plant from the house?
Ticket say it does gets 25' H x 15' W so do I plant it about 12 feet from the house?
Please, I need your help! Thanks
it has a completely non invasive root system so you can plant as close as you like. Regards Stephen
Have you seen cornus wilsoniana...??? I grew these I have from seed but the bark is gorgeous....kind of modeled of grey, green, tan colors...I should send you one of these...of course I'll probably be dead before it gets interesting...
I have indeed got Cornus willsoniana in my national collection and in fact have a number of young plants for sale at my nursery. Regards Stephen
great,,,, it was truly pretty when i saw it in Savannah GA and Raleigh NC.... perhaps i can live long enough to see it in it's prime....
💞✨Thank you both.
Well, that was very interesting to observe. I’ve always liked the look of Cornus, but, yet to place one in my garden.
I may have missed it, what’s the general spread of a mature Cornus?
Much appreciated. 🌿
The spread can be dictated by the space allowed but usually about half the mature height remembering that they aren’t all that fast growing so you may never need to worry about it! Regards Stephen
A question for one of your Q&As that came to mind during your fascinating Dogwood discussion: Do Northern Hemisphere plant species remain on the same flowering and dormancy schedule when grown in the Southern Hemisphere and vice versa or do they adapt to the local seasons?
A friend imported peonies from NZ to the USA, it took about a year for them to get on the USA schedule. A nursery importer said trees take a little longer. So yes, they change.
Thanks Theos - we'll add it to the list!
I grew dogwood seedlings from the red seeds. How old do they need to be before you can plant then along a woods
It depends on what competition they might get and if you can protect them from herbivores. Small is usually best. Regards Stephen
Hello Stephen and Matthew, I have just seen C. Greenvale in a Christchurch NZ garden with apricot coloured bracts. The owner advised: It colours like that at this stage of the year, starting off cream with a greeny tinge. Would this variety grow in Balgowlah Heights (and do its apricot tingeing) or are we better off with Eddie's White Wonder as I gather it copes better with warm climates? Cheers, Helen
We don't think we have Greenvale in Australia but its parentage would suggest it is a hardy one and should cope with some heat. As far as keeping the apricot colour I would assume aspect would be as important as climate so it would be worth a try. I do however love ' Eddies White Wonder' Regards Stephen
@@thehorti-culturalists Thanks Stephen
Dont forget cornus alternifolia , cornus sericea and the groundcover cornus canadensis! These are very cold tolerant and common in Canada. Completely different flowers, but berries follow as well as beautiful bare branches!
Probably yet another story! Regards Stephen
How would you propergate the cornus Florida from the wild so I can have one in my garden?
collecting seed when ripe would be an obvious way to start off young plants. Digging up young plants would also work but this may be frowned on by conservation bodies. You get them however from private property with permission of the owner. Regards Stephen
Thank you
Can you plant flower dogwood in the ground
Certainly. Regards Stephen
My soil is 8 alkaline can i grow dogwood and what if i can is the variety?
As long as your soil is fertile and rich in humus most dogwoods would be possible. keeping in mind the sheltered moist aspect they prefer. Regards Stephen
@@thehorti-culturalists thanks for that
Will loping of the top harm the tree as I don’t want extremely tall trees as I am on a handkerchief garden in my village in Eltham with Diamond Creek flowing behind the community grounds, where a tall dogwood and ginkgo would be seen but only when I come outside. Your friend Peter from Post Office Farm Nursery should be dropping of a huge package for me anytime soon. Had no idea you are doing something I should have begun many many years ago. I did follow the old saying when should I plant a tree TODAY! But moving after planting 18 times in 23 years I can only go and drive around looking for those trees!
Not happening.
I am designing my small backyard garden myself with a cross with a water feature in the centre and a path where I can use my walker safely! I watched your fastitgi trees and 2 ginkgos on opposite corners and 2 other trees like the old ballerinas on the two other corners may work and then lots of hellebores, bulbs, 😮 annuals on the edges, cyclamens popping up here and there (love that) hydrangeas, hostas, those little plants that look like little pipes or fly traps? Colour pink white green and purple.
I turn 72 next month and love gardens and visited so many in the many States I stayed in home and pet sitting as well as Canada, England the Netherlands (I was born there and we arrived on Melbourne Cup Day 1958 and not allowed to disembark due to a horse race I was 7 and I have vivid memories of the ship’s journey through the Suez Canal.
Thank you for sharing your story, experiences and love of plants, trees and gardens.
You must be in Heaven living in Macedon I actually sat in Woodend looking after dogs and tiny ponies. I also lived in Kyneton and then on a farm just near the mineral springs. 3 homes in 8 months???? I must have had rocks in my head at the time???
I don’t want to seem rude but no matter what you plant in the way of fastigiate trees as none are likely to get too big in the next 20 years. But if needs be they could be lopped but do it with some flare and not hack them down. Regards Stephen
Who’s the annoying fruit in the hat?
He is Matthew Lucas and he does introduce himself at the beginning of each video, and he is the only reason that the videos exist in the first place as he does the filming , editing and posting of our content every week. So without Matthew there would be no me! Regards Stephen
@@thehorti-culturalistswhy tolerate this homophobic comment? People like this should be ignored and shamed off the internet!
