Invasive Yellow Clematis
25 Jul 2018 |
|
Some of you will be familiar with this rather beautiful flower and its silvery seedheads. Unfortunately, despite its beauty, it is an invasive species and widespread. This is one of three species of Clematis that occur in the wild in Alberta, the other two being the native Western Clematis and the Purple Clematis/Blue Clematis. This yellow species was introduced from Japan as an ornamental garden plant, but has now spread to natural areas where it chokes out and kills native plants, shrubs and trees.
This photo was taken at the Erlton/Roxboro Natural Area, not far from downtown Calgary, yesterday afternoon, 24 July 2018. It is the richest botanical area, for its size, within the city. Over 385 species have been recorded in an area of about three hectares. (All of Fish Creek Provincial Park has only about 460 species). Eighty species, however, are aliens, now occupying 90+% of the Erlton/Roxboro Natural Area. It is such a shame to see how the area is being devastated by plants that include Baby's Breath, Creeping Thistle, Yellow Clematis and other invasive species.
The weather forecast for yesterday afternoon called for a risk of a thunderstorm. The sky was dark and gloomy, but we were very lucky that the rain stayed away. Our temperature at 9:00 this morning, 25 July 2018, is only 12C, which feels really good. This afternoon, it is supposed to get up to 23C.
Misleading beauty

Taken at Erlton/Roxboro Natural Area on 27 July 2011.
The Erlton/Roxboro Natural Area is located on the east side of the Elbow River above the southwest community of Roxborough. It was completed in 1996. This is one of the richest areas in Calgary for wildlowers, but unfortunately, many non-native plants and shrubs have taken over much of the area - such as Caragana, Goat's-beard, Baby's Breath and Yellow Clematis.
