Asteraceae – Aster family, Endangered

Pink coreopsis is listed as endangered both provincially and federally. We have created a sandy area on the shore along our stream especially for this plant in the outdoor collections of the Gardens. The plants were successfully transplanted outside in the summer of 2003 from research materials being used by the Faculty of Science. As pink coreopsis doesn’t do well with competition, the Gardeners hand pull encroaching weeds to allow for this ex situ population to flourish. Pink Coreopsis can also be found in our Coastal Plain section of the Conservatory, an area specially designed to allow for automatic flooding and draining on a daily basis to mimic the shoreline habitat where the plants naturally occur. The coreopsis is doing well in this sheltered location and allows for the up close study and observation of the species.

 

Water-pennywort (Hydrocotyle umbellata)

tl_files/sites/kcirvingcentre/resources/images/pennywort.jpgApiaceae – Carrot Family, Endangered

Water-pennywort is listed as threatened in Canada and endangered in Nova Scotia. This species in known to occur only in 2 lakes in South Western Nova Scotia; Kejimkujik and Wilson’s Lakes. This scarcely seen pennywort can be found in the Coastal Plain display of our Conservatory. The display floods and drains once a day to mimic the natural environment that these species are found in. So depending on the time of day that you visit you may find the water-pennywort underwater. If you’re lucky you will see it in bloom. You have to look very closely as the blooms are very small and delicate. We have this plant’s common relative Hydrocotyle americana growing outside in our stream at the foot of the Coreopsis planting. We have not introduced the endangered umbellata for fear that it would not survive in this unnatural stream setting.

Thread-leaved Sundew (Drosera filiformis)


 Droseraceae – sundew family, Endangered

 

Thread-leaved Sundew is listed as endangered across Canada. The only known location for this species north of Massachusetts is in Nova Scotia, in a select few bogs in Shelburne County. This remarkable little plant is a member of the Sundew family and is one of our native carnivorous plants, deriving its nourishment from the insect world rather than the nutrient-poor soil of the bog. The leaf blades are covered in long hairs that are coated in a sticky substance. Insects land on the leaves and are caught by sticking to the substance, then the plant creates enzymes that slowly break down the insect carcass so that its nutrients are available to the plant.
