Magnolia × soulangeana
- Position: full sun or partial shade
- Soil: moist, well-drained, acidic soil
- Rate of growth: average
- Flowering period: April to May
- Hardiness: fully hardy
One of the most popular magnolias, with large, dark green leaves that start to appear in mid spring, at about the same time as the huge, deep rose-pink or white, goblet-shaped flowers. This is a good magnolia for smaller gardens,as it remains a shapely shrub for many years, and even when it is mature, is a manageable small tree.
- Garden care: Requires minimal pruning. Remove any broken, diseased or crossing branches in midsummer. The best time to plant is in April, adding plenty of peat to the planting hole, in a sheltered spot. Mulch in spring with manure and leafmould, especially on dry soils.

I have a 8yo Magnolia. Can I plant crocuses under it?Asked on 30/4/2016 by Ava from US
Yes, crocus would look lovely beneath your Magnolia.Answered on 3/5/2016 by Helen from crocus
will you please let me know when you would expect the Magnolia Soulangeana to flower (after how many years) if purchased as 3 litre pot compared with 12 litre pot?
JudeAsked on 22/4/2016 by Jude from United Kingdom
These tend to be pretty free-flowering from an early age, so given the right conditions, you may get a few buds on the smaller size in their first year after planting.Answered on 25/4/2016 by Helen from crocus

Q:Will Magnolias survive really cold winters
Thank you for the information on Magnolias. However, we live 1000 ft above sea level in Mid-Wales and had temperatures in January 2010 down to Minus 16C. Can I really grow Magnolias in our situation? MargaretAsked on 14/4/2010 by DerekandMaggie Parker
A:Hello Margaret, The Magnolias we sell are fully hardy in most areas of the UK, however the best indication of what will grow in your area is to see what is already there. Alternatively if you really get blasted by wind or freezing temperatures and you want plants that usually won't tolerate these conditions, then perhaps you need to create a shelterbelt, which will produce a microclimate. I'm sorry not to be more help. Helen Plant DoctorAnswered on 15/4/2010 by Crocus Helpdesk
Q:Plant advice for 2 new beds please
Hello, I need some help to decide which plants to put into two new areas please:- 1: A semi-circle flash bed at the front of the house, size approx 2m x 0.80m and 0.80m deep. I thought about the 3 following options for a small tree/bush in the middle:- a) Magnolia soulangeana, but I was worried about the size that it could grow to and possible problems with roots etc . Will it stay small if the size of the container is used to restrict it? b) Witch Hazel (Hamamelis intermediana 'Diane'). Will it spread too much? I think this is very pretty. c) Corylus avellana 'contorta' Then I also need to think about ground cover plants to help suppress weeds. I am only interested in fully hardy, easy to look after plants, could be with some flowers or coloured leaves. 2:- A thin path between neighbours (approx 2m x 0.40). My idea is to plant bamboo. I would love a modern thin run of bamboo with ground cover. My worry is which bamboos to use. I love the yellow, like Phyllostychys aureocaulis (Golden Grove) but not sure if it is strong enough as it could be exposed to some wind. I bought from you a couple of years ago the Phyllostychys aureosulcata 'Spectabilis' which I planted in pots but it died this year. I see on your website some other bamboos but I don't like them as much as their canes seems less exposed and have a lot more foliage. But possibly these would be a better alternative... ...? For the ground cover I as thinking of Ophiopogen nigrescen. Do you think these plants will be suitable, or have you any other suggestions? Thank you for your help, GaliaAsked on 15/2/2010 by e moran
A:Hello Galia, All of the taller shrubs you mentioned for the semi-circular bed will get quite large, but their growth will be restricted (both in height and spread) if they are kept in a pot where their roots are restricted. For groundcover you could opt for any of the following:- Bergenia http://www.crocus.co.uk/search/_/search.bergenia/ Helleborus http://www.crocus.co.uk/search/_/search.helleborus/ Heuchera http://www.crocus.co.uk/search/_/search.heuchera/ Epimedium http://www.crocus.co.uk/search/_/search.epimedium/ Geranium http://www.crocus.co.uk/search/_/search.geranium/ Erica http://www.crocus.co.uk/search/_/search.erica/ As for the bamboos, even the most well behaved one (Fargesia murieliae) will spread to around 1.5m across so you should keep this in mind when planting it in such a confined space. Perhaps a better option would be one of our hedging plants, which can be cut back hard against the wall. Taxus http://www.crocus.co.uk/plants/_/shrubs/trees/hedging/conifer/bigger-trees/best-in-very-large-gardens-parks/taxus-baccata-/classid.6230/ or Ligustrum http://www.crocus.co.uk/plants/_/shrubs/hedging/ligustrum-ovalifolium-/classid.4093/ would be good options. I hope this helps. Helen Plant DoctorAnswered on 16/2/2010 by Crocus Helpdesk
Hi, I have just taken delivery of a Magnolia (Star Magnolia). At the moment it is outside, in the bottom half of the box. I have just checked on your website and it says it is best to plant in April. What should I do with it in the mean time, and how do I care for it? Regards LauraAsked on 10/12/2009 by Laura Steed
A:Hello Laura, These are fully hardy so, although the optimum time for planting is spring or autumn, they can be planted out at any time of the year as long as the ground is not frozen. Therefore I would recommend you get it into the ground as soon as you can. I hope this helps. Helen Plant DoctorAnswered on 10/12/2009 by Crocus Helpdesk
A:Hello Helen Thank you for your help - I will do as you suggest. LauraAnswered on 10/12/2009 by Laura Steed
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:Magnolia tree pruning
Greetings, We have a very mature Magnolia tree which grows from five thick stems (6 inches across) from ground level. The canopy starts from 4 feet and it has grown now 20 feet. It flowers well and often has a second flowering in September. It is a well known tree in our rural area. Can I prune the tree down to six feet in height with the hope it will send up sapling growth and then I would be able to control the height from ground level as now owing to heath problems I am not allowed to use step ladders. In anticipation --much appreciation.Asked on 20/9/2009 by Dick Brown
A:Hello There, It can be risky, but many Magnolias will slowly recover from being cut back hard, although it will take a few years to regain its composure. If you have a spring flowering type, then the best time to tackle this is in mid summer after the flowers have faded. It is important that you do not prune them from late winter to summer as they are prone to 'bleeding'. I hope this helps. Helen Plant DoctorAnswered on 21/9/2009 by Crocus Helpdesk
Q:Choosing the right plant
Hello, I'm trying to find a suitable plant for my back garden, its south facing and its a clay soil. We live in a new build house so are overlooked. The plants are for at the bottom of the garden away from the house so we want plants that will give us privacy. I have been looking on your website but can't choose what to have. I am thinking that a Magnolia would be nice but I am not sure which one to choose. As I have no other plants in my garden, this will be the focal point for a while! Any help would be appreciated. Thanks SamanthaAsked on 14/9/2009 by Samantha Walsh
A:Hello Samantha, I love all the Magnolias, but the ones with the cup-shaped flowers are my favourite. Magnolia Susan is relatively compact and has lovely dark coloured flowers - just click on the following link to go straight to it.
http://www.crocus.co.uk/plants/_/shrubs/magnolia-susan/classid.4143/ If your soil is not strongly acidic or alkaline (you can check this with a simple test kit which we sell) then I would check the information on our site and pick one of the Magnolias that you like the look of best. I hope this helps. Helen Plant DoctorAnswered on 14/9/2009 by Crocus Helpdesk
