First introduced to the UK in the early 90,s by error when it was mistaken as Trachycarpus takil. Its superior stature to regular fortunei was mistaken as characteristics of Trachycarpus takil. The palms were introduced to that part of India in the late 1800,s by British colonials trading tea with China, confusing it with the native Trachycarpus takil. Wonderful seed bearing examples can be found in the himalayan hill town Naini Tal. It is also sold under the name of Trachycarpus khumoan, referring to the region from which it comes.
Hardy in most parts of the UK, it is an easy and trouble free plant, and can be used to form the backbone of any tropical garden. It seems hardier , more vigorous and larger in all parts than regular Trachycarpus fortunei.
Best planted in the ground in a well drained spot , they are not fussy although will not appreciate poor drainage. Dig them into the ground with a mix of garden soil and organic matter , and make sure they are watered regularly during the first year. A common mistake is to not water them , they will need regular watering until the roots go down into the ground.
It is not recommended as a pot plant long term, they dont like long term pot culture without regular repots.
You should also avoid planting them in exposed locations as the wind leaves them looking tatty. Trachcyarpus wagnerianus would be a better option.
Once planted , 2 or 3 dressings a year with a good Slow Release palm fertiliser is all thats needed to keep them healthy.
