Tulip Garden News & Data
"Our best Earth Day present came from our delightful Journey North tulip garden which bloomed for us today!"
wrote Mrs. Conroy on April 22nd. "Now we are waiting for the tulips to bloom in my garden up in Madoc, ON

Discussion of Challenge Question #7
Curious results were reported in our April 10th update, so we asked you to consider the cause.
Challenge Question # 7 asked, "Why do you think the Scotland garden (60.52 N) bloomed at roughly the same time that gardens in Fairlee, Vermont (43.91 ), White Bear Lake, Minnesota (45.09 ) and Winifred, Montana (47.63) were just emerging?"
Due to el Nino, we've heard a lot about ocean currents this year. However the Gulf Stream is probably the most well-known current in the oceans. As this map shows, warm water from the Caribbean Sea and the Gulf of Mexico are carried northward to Europe by the Gulf Stream--directly to our tulip garden in Scotland!
Despite the big difference in latitude, notice that ocean temperatures yesterday near Scotland are similar those in the mid-Atlantic States. Thanks to the Gulf Stream, Northern Europe's growing season is much longer than Canada's, even though both regions are found at the same latitudes and receive the same amount of sunlight.
Look carefuly at this map of the Gulf Stream. Can you find the region along the U.S. coast where the Gulf Stream veers off toward Europe? Next see if you can answer this question:
The WWW is full of information about the Gulf Stream, including great activities for students such as these:
Are Your RED Emperor Tulips YELLOW!?
Many people were surprised this spring when their tulips bloomed! We sent out an alert last September which many people seem to have missed.
Due to disease in Holland, there was evidently a shortage of RED Emperor tulips last fall. Therefore, our supplier
encouraged people to order early-- When their supply was exhausted, they explained they would have to substitute
By the way, we were told all colors of "Emperor" tulips should bloom at the same time, regardless of color. In our garden, yellow tulips bloomed 2 days earlier than the orange. We're curious to know:
