Plant of the Week: Tulip Tree

Liriodendron tulipifera or Tulip Tree, also known as Tulip Magnolia, Yellow Poplar, and Whitewood, is member of the family Magnoliaceae, the Magnolia family. Liriodendron is a small genus, which includes the Tulip Tree. Its naming comes from the Greek leiron ‘lily’ and dendron ‘tree’. This pioneer species in North America originally had its inner bark used medicinally as a worming medicine, anti-arthritic, cough syrup and cholera remedy. Its wood is fine grained and stable, making it useful for the construction of canoes, cabinet making, and furniture framing. Read More

Nature Sanctuaries

The fragrant white water lilies are blooming in the Hendrie Valley ponds.

Don’t forget to stop and smell the roses! RBG has several native species of roses which are now flowering in the nature sanctuaries.

The large white umbels of flowers have appeared on the cow parsnip, remember to look but not touch! Cow parsnip has toxic sap that reacts when sunlight hits affected skin.

The weird and wonderful ghost plant is now flowering! Keep your eyes peeled along the trails on the south shore and in Hendrie Valley, and don’t mistake this plant for a fungus!

Bloom Times

Bloom time is often influenced by many natural events including temperature and climate. As these can vary from year to year bloom times are influenced by these factors. Below you will find ‘average’ bloom times for a number of RBG’s collections but please bear in mind that if we experience an early or late spring, bloom times could shift up to 10 days earlier or 10 days later.
