High Park is the best remaining natural area on the City of Toronto’s Iroquois Sand Plain... The flora of High Park is outstanding for its 102 extant significant species (4 provincially rare, 9 regionally rare and 89 locally rare plant species), many with southern/western and prairie/savannah affinities. A number of the rare species, particularly those in the cool ravines, also have northern affinities.

Find Your Plants by Feel and Smell

A plant with silica crystals (sand) in its leaves making it shed water? Yes, and you can find it growing where water trickles down the steep hillsides that run up from Spring Rd. It’s known as Scouring Rush or Horse Tails (Equisetum hyemale) and is designated as a menace in Australia, very invasive in the U.S. and a joy to modern flower arrangers here in Canada.

AVOID POISON IVY

Learn to recognize three leaves of poison ivy (Rhus radicans), notice how the middle leaf stalk is always elongated. Leaf arrangement is your main clue as this plant can take many forms and sizes: from a small ground plant to a shrub or a vine.

All parts of the poison ivy plant contain urushiol, allergenic oil mixture that causes itchiness, irritation, and sometimes painful rash in most people who touch it. Your clothes and pets can transfer the substance to your skin even after you leave the park.

Macrophytes – Wetland Workhorses

Macrophytes are plants that grow in or near water. They may be emergent (growing out of the water), submergent (growing under the water), or floating. Along the shallow edges of ponds and lakes, macrophytes provide cover for fish and habitat for aquatic invertebrates and other wildlife. They also produce oxygen and act as food for some fish and wildlife.
