The plant of the week this week is a widely planted shrub that’s really starting to look great at this time of the year. And it rightly deserves this wide planting for its a tough plant
Garrya elliptica ‘James Roof’ is a evergreen shrub that sometimes is called Silk tassel bush or Quinine bush. It is a native of USA where it grows in a couple of different areas, the first one is on the coast of South Oregon and into California very near the coast well within 20miles of it. The other place it can be found growing on the mountains around the Pacific coastline in areas like Montana and San Bruno mountain ranges. It tends to grow 200m above sea level in the more damper spots along the coast.
It was first discovered by one of the greatest plant collectors of all America, David Douglas in 1828. Garrya was named after Garry Nichols. Garry Nichols was the deputy governor of the Hudson Bay company and managed the merger between them and North West Company. Hudson Bay Company controlled the fur trade throughout North America and is still going as a trading company selling anything from clothes to digital space. The cultivar James Roof was named after the director of Tilden botanical gardens, California where this form was found growing in amongst some seedlings.
Garrya elliptica ‘James Roof’ is an evergreen shrub with a sea green foliage. It makes a shrub that will reach 4m in height and width and makes both a great free standing shrub as well as a wall Plant. Garrya elliptica ‘James Roof’ makes a Great Wall shrub thriving on a north facing wall. It’s grown for its very beautiful greenish/grey catkins at start showing early winter and then open up around now to their full length of 20-35cm in the case of the male form James Roof. These catkins are really what this stunning shrub is grown for. Once they have finished flowering, they can stay on the shrubs for months after they have finished. It is pretty tough shrub, Hardy down to -15c but it will suffer a bit of browning on the leaves and some dieback at these temperatures. It prefers a soil that is pretty damp but is free draining, it will survive in drier soils but never does as well. It will quite take slightly acidic and alkaline soils, ideally in the PH range of 6-8. I have grown it on shallow soils over chalk without too many problems. It’s prefect for poor soils and coastal areas. Pruning wise it just needs a little shaping in April cutting the growth from last year down to a couple of buds on established plants and trim new growth on plants in training, down by half. Feeding is down using a compost mulch and vitax Q4 in around March time. Propagation is best done by semi-ripe cuttings taken in late summer. It is pretty disease and pest free, rabbits and deer don’t really like eating them!
Garrya elliptica ‘James Roof’ is available in most good garden centres and can be seen in most public gardens and in a lot of private gardens as well
