Late fall colours are still in full bloom at the TBG, thanks to our wonderful autumn weather!All these selections are featured in the Entry Garden:


Tricyrtis formosana Samurai (Toad Lily); Samurai is the most popular cultivar of toad lily, growing best in shady areas; this selection has purple flowers with darker spotting held above green foliage edged with gold – perfect for the autumn garden as is a later flowering perennial

Sedum Autumn Fire (Stonecrop) ; similar to S. Autumn Joy but with a tighter growth habit so it is less prone to flopping over. Autumn Fire was developed in Quebec and also displays brighter rose-coloured flowers than Autumn Joy. It is shown here with a touch of frost

Eragrostis spectabilis (Purple love grass); hardy to zone 5, this tufted grass is short at 10″ with plumes reaching up to 2′; an underused perennial very unique! it prefers a sandy situation.

Geranium phaeum Album (Mourning widow cranesbill) ; this geranium is mound-forming with deeply lobed foliage and delicate white flowers, a very hardy selection tolerating dry shade better than most, excellent for woodland gardens. Here the leaves are touched with the first fall frost.

Cotinus obovatus (American smoketree) ; Native to the southeastern United States, this small tree is hardy to zone 4 with autumn foliage in a variety of colours from yellow and orange to reddish purple,making it one of the best fall colour small trees. With its interesting bark, it makes a great specimen!

Viburnum nudum (Northern Wild Raisin or Witherod); this native shrub belonging to the honeysuckle family, is definitely underused in home gardens. It has edible fruit and its glossy leaves turn a rich burgundy in autumn.
