Answers From The Tulip Expert
Mary Hockenberry MeyerExtension Horticulturist and Assistant Professor University of Minnesota
From: MINNESOTA Q. Last week we had some very unseasonably cold weather. A number of our tulips froze. The short leaves are yellow and look dead. Some of the plant is still green. The big question echoing around our school is will the tulips bloom? Thank You
A. Maybe ! It depends if the flower buds were frozen. Plants that had not
emerged will be ok, others may have yellow or white leaves and still
flower, still others may be nothing but white thin foliage. Tulips are ok
at 25 or even 20 degrees, but not at 8 degrees which was what the Twin
Cities had ! the plants that look the worst this year will not recover and
will not be here next year, the food reserves from the bulbs are gone and
with no green leaves the bulb cannot form again.
From: MINNESOTA
A. Temperatures below 20 degrees can be fatal to tulips. Any part that is
frozen will turn white and not be able to make sugars for the bulb for next
year, or for the flower to continue to form this year. I expect you will
see a few small flowers, or deformed plants but not many flowers.
From: MINNESOTA A. Yes, they will still grow if more of the plant is below ground that what was above when it froze. Tulips do not like temperatures below 20 degrees, but because much of their stored food is in the bulb below ground you may still see some flowers. Q. Were do tulip bulbs come From? Leif Anderson, grade 4 A. Tulips come from the Mediterranian region of the world, Turkey and Persia Iraq) were the countries where people first collected tulips. Today many tulips are grown in Holland and the Netherlands and imported into the US and the rest of the world. Q. How do the bulbs turn into tulips? Ellyn Wukmir, grade 6
A. Inside each bulb are small leaves and a flower bud. If you cut a tulip open
you will see these, but they are tiny and white and look like the rings or
circles we see inside of onions. Onions and tulips are actually very
similar. Temperatures and moisture are signals for the bulbs to begin to
grow and cause the cells in the rings to elongate and grow into the leaves
and flowers we recognize. The bulbs must be planted in the fall, them have
many hours of chilling or cold temperatures, (this is our winter) and then
the flower bud will enlogate and grow. Without the moist fall and cold
winter the bulb will not gorw, it needs the cold temperatures and moisture
to signal the flower bud to grow.

From: FLORIDA A. tulips form seeds, if you leave the flowers on the plant you willsee a swelling on the stem where the flower was. When the stem is brown and dry you can cut this open and find the seeds. Q. What colors can tulips be naturally found in? A. Many colors, especially reds, oranges and yellows. Q. What parts of the world are they naturally found in?
