I always love to travel to my local botanical gardens in my city, i am lucky , i have two botanical gardens not very far from me, one is Toronto Botanical gardens and one is royal Botanical gardens in Burlington Ontario, the Toronto Botanical gardens is smaller compare to Royal Botanical gardens due to located in a Highly population city ( we have 3 million people) but still very cute and pretty in a river velly , the royal Botanical gardens has 6 major theme garden and occupied 2700 acres and , and that area has many swamp, marsh, nature conservation, river and forest area, in one of the area in a forest it design to restore many native plants and trees , which also a queit area because many tourists only like to go to rose garden/tulip/peonies garden, and don't find the so much attractive in native garden, there is a boardwalk through the garden and designed trail because they don't want people step in the forest because many native plants are fragile, and also all pets needed to be least .in here the garden keep most of the forest in the original look from the 1960th since they bought the land, and restore and planted some none native plants to attract tourists ( like over 200 different varieties of hostas and many varieties of ferns and perennial) , so for example in the spring time you would see Trillium and virginia bluebell(Mertensia Virginica) but also variety of perennial like bleeding heart blooming together, you see many woodland plants like hellbores , Japanese fern, European anemone grow together with May apple and Soloman seal and ostrich fern, i once a time express my concern of they are using lamium yellow archangel for ground covering plants and the gardener said they are under control and it is not considered invasive, and they are zigzag Goldenrod and wild strawberry and wild ginger too, what do you think ? Should it be all native in a so called native forest theme garden or it is okay to display some none native plants for business and season interest? I admit when you see a big patch of hellbores , purple ligularia , rodgersia or bleeding heart it is really beautiful, however in someway they are also occupy native plants like swamp milkweed, cardinal, great lobolia etc spaces. Well it is all about business and they try to balance both .
