Title: Chimonanthus praecox
Post by: Hans J on January 08, 2014, 04:16:50 PM
Hi all ,

a friend of mine has suggest me Chimonanthus praecox ...he told me it has wonderful fragrance
but I have it never seen here in Germany  ( or maybe I have it seen and I was thinking it a Hamamelis  ???)

If anybody here knows this plant so I have some questions :
How hardy is it ? ( I live in Zone 8a)
Any advices for soil ?
Sun , semishade or shade ?

For all suggestions I would be glad
Hans

Han:   Uli Würth  ("Onion" in the Forum) works with shrubs - he will be the best man to advise on this plant  for your garden, I think.

It is grown in the UK, I know  - does quite well at Wisley, I believe.

I really don't know if it grows much here or not - when it comes to shrubs I am   rather blind when it is not a rhododendron  :-X :-\

I have one in our central Scotland garden.
In a mild winter such as this it is evergreen but it did tend to lose its leaves in the winters of old.

Our plant is rather open and leggy being partially shaded by an Ash tree. It produces very few flowers (? due to shade) and in our modest sized garden does not really pay its way.

Hans,

 I grow this plant and it is (was?) currently in flower. I brought a branch in for the fragrance which is sweet and musty somewhat like Musacari muscarimi. It is fully hardy down to -10 F as I have had it in my parents garden in Kansas for over a decade. It rarely flowered there though. Even in my current garden it does not remain evergreen and I don't think it is a real evergreen in the true sense. My plants lost all there leaves, or most of them before the first frosts this fall. Semishade and some moisture is good. It has a broad distribution in China and there are many forms of it.

 I've never gotten seed on mine, but cuttings are easy in early summer.

Aaron - Chimonanthus praecox from a very hardy form ex Hangx Houi B.G. Zhejiang, China (I presume they meant Hangzhou BG) was killed outright at +5-+10F.  I guess we do not get enough heat to ripen it properly.

johnw  - -3c, blazing sun

There is one at college (Worcs): South-facing wall/full sun. 12 ft high; flowers prolifically; can smell it from 100yds. Came through -20oC without damage.
Several cvs are available http://www.chris-pattison.co.uk/shrubs.html (http://www.chris-pattison.co.uk/shrubs.html)

This has a wonderful scent but it's not a good looker.  Best tucked away behind something else but near a path.

Hi Hans,
I had this shrub from a nursery in Gießen ( Engelhardt) about 1m high, but here in the Sauerland it didn't survive, but in your area it should.

Kind regards, Martina

True John, heat seems to be a requirement for hardiness to fully ripen the wood.

Chimonanthus praecox ("Wintersweet") is one of the various winter-scented plants grown on the famous "Winter Walk" at nearby Anglesey Abbey.  The scent is my favourite of all the scented plants there.  The various shrubs on the walk are quite densely-packed so I guess that gives it some shelter.  It never flowers prolifically; some years and some specimens are better than others.  But to my mind it is still worthwhile because the scent is so good.

Hans,
we grow this plant in the nursery. To your climate it is full hardy. The last winters damaged the large plants (2, 5 Meter), but they survived. The grow in Zone 6b (Forest Botanical Garden Goettingen). The problem is to get a plant that flowers good.
Plants propagate by seeds are often " bad  flower"-examples.
You need acid soil. Not like as for rhododendrons but pH 6,5 must enough.

This is Chimonanthus praecox flowering today here in Kent. Fully hardy and definitely deciduous. I wouldn't be without this shrub for its exotic scent in midwinter, so I grow it next to the path. Agreed, it is not a looker in summer with boring green foliage, but it puts on some good autumn colour, turning butter yellow.

Thanks to all plant lovers who have responded to my my question - the information is very useful for me ... I think I'll try such a plant in my garden.
This morning I had some phone calls with nurseries in my area ...one nursery had a plant ...so I can look !

A nice friend wants to send me some seeds ...

Thanks again for your help
Hans

Hi Dom,

Thank you for your advices  :D - your plant Looks very nice with those many flowers

Good news from me :
We have bought yesterday this shrub  ;D
It is a big plant with 1,5 m high

The fragrance was not so remarkable ( maybe because the flowers was since long time open)

Again thank you to all
Hans
