Chinese Rowan - Sorbus aucuparia / Sorbus rehderiana


Browse all of our other Rowan trees, Whitebeam & Wild Service trees here.

An excellent variety, Joseph Rock has smaller, lighter coloured leaves than most other Rowans, giving the tree a more open look.
The flowers come in plain clumps of creamy white.
This tree really stands out in autumn, when its leaves take turns to flush with reds, coppers and purple-brown tones.
Amongst the leaves are the maturing fruit, which are much showier than the flowers that produced them. They change from milky yellow to a rich amber colour and continue to decorate the tree well after the last leaves have fallen.
We reckon that this is one of the best ornamental trees to bear orange-yellow fruit.


Although there is some uncertainty about its origins, it is probably one form of the variable species Sorbus rehderiana, taken from the mountainous forests of the Chinese province of Yunnan in the 1930's (because of its pinnate leaf stucture, it often is classed as an aucuparia).
Joseph Rock was an Austrian explorer, though made his home in Hawaii when he wasn't exploring China, and spent over 25 years recording and studying Chinese plants, geography and language.
Sorbus Jospeh Rock
will only reach about 9 metres, 30 feet high, with an upright growth habit.
Being small, fully hardy and tolerant of pollution, this is an ideal tree for a small garden, either in the city or an exposed inland area.

Planting Sorbus Joseph Rock

Sorbus aucuparia Joseph Rock will be happy in any well drained, acidic soil type.
It doesn't like chalk or more than partial shade.
We recommend it mulching it well in late spring and, if your soil is a bit dry, giving it a weekly soaking in a very hot summer.

Sadly, this tree is susceptible to fireblight and it is worth finding out if it is a problem in your area before choosing this tree.
Wales and South England are the most common places to find it, while colder areas north of Leeds should have nothing to worry about.

Please watch our tree planting video for full planting instructions.

How Standard Trees are Measured:
All the plants in the ornamental trees section are graded as standards, which means that they are measured by their girth in centimetres 1 metre above ground level (basically, their trunk's waist measurement). They aren't measured by their height, which will vary.

So, a 6/8 standard has a trunk with a circumference of 6-8 centimetres and an 8/10 standard has a trunk 8-10 centimetres around.

This measurement makes no difference to the tree's final height. Most standards are between 2 - 3.5 metres tall, but this is just an average. We cannot tell you how tall your trees will be before we deliver them.
