An unusually cold winter contributed to a late spring with most flowers blooming at least 2 weeks behind normal schedule. In 2013 provincially rare Harbinger of Spring (
Erigenia bulbosa) began blooming on April 9th. This year it bloomed on April 18th. Moreover, this is the first time that I have observed blooming on May 1st. Surveys of this population of
E. bulbosa exhibited a marked increase in the total number of plants by 2.5 x with 288 plants counted. Of these 198 were 2 leaved plants and 2 were seedlings. No seedlings were found in 2014.
A field training course at Cawthra Woods, Mississauga, Ontario for the
Association for Canadian Education Resources/Climate's Sake (ACER) staff contributed three new flowering date records for Peel region - all of which were cultivated or introduced species; Siberian squill (
Scilla siberica), Croccus (
Croccus longiflorus) and Grape hyacinth (
Muscari botyroides). We also discovered a new record for Witch hazel (
Hamamelis virginiana) and European spindletree (
Euonymus europaea), but these shrubs were not flowering. I would like to thank ACER for hosting a great day with their staff.
