    Tetraploids have more chromosomes to cause thicker leaves and wider margins.

    I have six. Of those six, three are from Francee. Patriot, Minutemand, Fire & Ice. Yet I don't have Francee.

    Blue Mouse Ears, American Sweetheart, and Grand Tiara are my others.

    There's at least one not on those lists.

    Essence of Summer (Warwick Essence), a stunning fragrant hosta with flowers that almost match plantaginea flowers for size

    bobinfrance- Thank you for the list of possible additions. I'll research those on your list in an attempt to verify these are tetraploids. Do you have a source I may refer to?

    sugarman- 'Essence of Summer' is already on the list posted :)

    Here are links to two Internet articles about tetraploid hostas:

    "Tetraploid Hostas" article by Bridgewood Gardens

    A definition of "tetraploid" by Westside Hostas FAQ's including a link to a scientific study of tetraploidism

    One web site which posts a Glosaary of Hosta Terms defines "tetraploid" as follows: "Tetraploidy is the trait of having twice as many chromosomes as what is "normal." Normally, the pollen provides one set of chromosomes from the male plant (pollen parent), the ovary provides a set of chromosomes from the female plant (pod parent), so the seed has a complete set of chromosome pairs (and so is called diploid). Either by natural or biochemical manipulation of the cells in the plant, it is possible to have plants with two (identical) sets of chromosomes in each cell. In hostas, there is a species that is naturally tetraploid: H. ventricosa that has the rare capability to produce seed by apomixis, or asexual means without benefit of pollen. By treatment of tissue cultures, hostas can be "converted" to tetraploidy, but this hasn't been done in hostas as much as it has in daylilies. Tetraploid plants generally have more vigor, substance, larger blooms, etc. A drawback of tetraploid plants is that the pollen is significantly larger (to hold the extra chromosomes) and so is difficult to use in breeding new hostas. Triploid hostas result from crossing diploid with tetraploid plants, and are effectively sterile."

    Tetraploidism in hostas has been achieved by the application of certain herbicides. Some people are using Surflan and Treflan to do conversions. This is much safer for people than colchicines, but not as safe for the plants. I'm not sure of the concentrations or the best methods of applying it. Some of these were perhaps accidental conversions, but others appear to be applying these herbicides intentionally to encourage tetrapoidism in hostas.

    Are there any articles that someone could post that would provide good reading? Are there articles from previous Hosta Journals or other hosta and gardening books?

    Don

    PS I'll plan to post all of my hosta lists on the Hosta FAQ's Page in the next few days :)

    Don, the list was given to me by Tim Saville, the holder of the British National collection of tetraploid Hostas so it should be pretty acurate.
    My main aim this year was to add more Tets. to my general collection of Hostas and now have about 25 to date.
