[Plant-education] Dried flowers for Botany class

Hi....You may want to try freezing flowers for class use.  I collect floral material, place it in Chinese food take-away containers (purchased inexpensively from a local restaurant supply house) and then simply stick them in the freezer until needed.  The flowers are a little mushy when they thaw but they have the advantage of retaining color and much of their form.  I'm sure any container will work but one advantage of the food containers I use is that they are not air/water tight so the flowers will freeze-dry if left long enough; which is especially nice because they maintain shape and color AND structure, and they can be dissected though are a trifle brittle.  All the best, Steve

Does anyone know of a company that sells good flowering material (fresh
or dried) that is appropriate for use in a plant systematics lab? 

Currently, I collect my own flowers and press them for use in class, but
wonder whether there is a vendor out there that supplies them to college
teachers.  I realize that florist shops can supply some of these
flowers.....but what about things like catkins from spring-blooming
trees?   Or grass flowers (of a particular species)?  Or cactus flowers?
Etc?

Is there a vendor for these kind of floral specimens (fresh or dried)?

Thanks for any help.

Beverly,
I would recommend Environmental Growth Chambers (EGC) in Chagrin Falls,
OH  http://www.egc.com/  I have had experience with a variety of
different EGC controlled environment chambers when I worked with the
USDA-Agricultural Research Service.   Currently we have eight of their
Sunbrellas in our plant growth room.

Blessings,
John Silvius

We're going to purchase an environmental chamber to facilitate our
interdisciplinary teams' work with germination and sprouting seeds.
We
would ideally like one large unit that can be set to two different
conditions.  I haven't been able to locate such a beast yet.

Does anyone have suggestions for chambers that have worked well for
them?
Questions to make sure to ask? We're thinking we would like it to vary
lighting, heat above room temp, cool below room temp, and humidify.

Thanks in advance for your help!
