Trollhaugen Grape
Trollhaugen Grape
Species: Hybrid, contains Vitis labrusca and Vitis riparia
History: Trollhaugen is one of several varieties created by grape breeder Elmer Swenson in Wisconsin as part of an effort to create more grape varieties that can be grown in our cooler North American climates. It was developed by Swenson in 1985 and released in 2000, although the variety was named by David McGregor, the first winemaker to market wine in Minnesota. Trollhaugen translates from Norwegian as 'troll mound' but it is possibly named for the Trollhaugen ski resort in Wisconsin.
Why We Grow It: These Concord-like grapes have a mild, sweet flavour and are seedless. The vine is very vigorous and cold hardy, and produces medium clusters of small to medium grapes. Excellent for the home orchard!

Shipping vs. Pick Up

CLICK HERE to see how shipping compares to pick up.
Shipping: Every year we ship thousands of trees across Canada (except BC due to CFIA regulations). We carefully bag roots in damp sawdust, then box them and send them out via courrier. CLICK HERE to see our shipping policy.
Pick-up: We also have thousands of trees picked up from our nursery each year. The pick-up options is free, though you must wait until you have been emailed a confirmation that your order is ready to pick up, which will have further information such as hours, locations, etc. We really appreciate if you can make an appointment to pick up, then we can be as organized as possible during our busy season.

Grapes are divided into the following grades:
- 1 year plant - pruned to ~20cm, well-rooted
- 2 year plant - pruned to ~30cm, extensive root system
There is some overlap in size since we are also taking the age of the plants into account. Some older plants may not have put on quite as much vegetative growth but will have larger root systems.
Unless specified, heights exclude the roots since seedlings and some berries will often have a lot of root growth but relatively little vegetative growth (ex. our Shagbark Hickories seedlings are often 5-15cm above the soil but will have roots that reach 20cm+ in length).
Not all of our berries and seedlings will be available in all of these grades since growth rate can vary significantly across species and even varieties. While we remain competitive in our plant size, it's also worth noting we don't use synthetic chemicals to push vegetative growth, therefore you may find conventional nursery stock larger in some instances comparatively.
