Perhaps the most well-known component and certainly the biggest display area is the rock garden. It can be divided into two sections: the old and the new. The old part, constructed in 1972, is in the traditional style: a sloped bank, located in full sun, with a series of rocks and terraces to represent a mountainside. The rocks are fairly small and were placed by hand. The area was filled with a well-drained soil mix of screened topsoil, leafmold, and coarse sand (1:1:1), the whole area was then mulched with a two inch thickness of crushed rock. The new rock garden’s main feature is the mountain gully. An obvious difference between the mountain gully, opened in 1993, and our other rock garden is the size of the rocks. Some are the size of small cars! Over 200 tons of rock and more than 80 tons of mixed soil were used to create the mountain gully. A small pool, stream and a series of waterfalls were added in 1995.
The new rock garden also has a limestone garden and scree built in 1989 with limestone donated form a quarry in Corner Brook on the west coast of Newfoundland. In this bed are lime-loving alpines including our native yellow lady's slipper (Cypripedium parviflorum) as well as pinks (Dianthus), primroses and pasqueflower (Pulsatilla vulgaris). The limestone scree is a representation of the limestone barrens of northern Newfoundland. This garden is truly a garden on rocks and features an assortment of small native Newfoundland arctic-alpine species such as saxifrages, pussy-toes (Antennnaria), roseroot (Rhodiola rosea) and dwarf goldenrod.
