My university carried out a test, the've planted almost a hundred varieties
of tulips and daffodils in 1994, the arboretum is in Z5, but on a southern
slope of a hill.

Most daffodils do well in the clay soil of the Arboretum, exceptions are the
Tazetta group, like Ziva, Poetaz daffodils do well but they don't provide a
sensational color, example: Soleil D'or, others like Geranium, Cragford,
Silver Chimes are growing very well, altough they are plantd in grass under

From tulips mostly Kaufmanniana, Fosteriana, Greigii hibrids doing well, but
it is influenced by bulb size. They've planted Viridiflora, Parrot tulips in
half shade, 12/+ in 2007, they still doing well, 10/11 sizes had only a few
flowers. Lambada is a nice variety, susceptible to TBV but still flowering
well. Stresa, Fashion, Showwinner, Johann Strauss are performing well, Red
Riding Hood is not Cape Cod, Juan, Purissima, Orange Emperor are also good.
Darwin -hybrids need a sunny spot to perform well, so as Fringed
Lily-flowered and Parrot types. Botanicals are also good, T. tarda,
violacea, turkestanica flowering and propagating well.

Crocus: chrysanthus types are better, especially in rockg garden with Iris
reticulata. Crocus vernus in not performing well after a few years.
Galanthus, Muscari and Allims are naturalizing, while Erythroniums vanish
after 3 years or sooner. Scilla siberica, Chinodoxa, Scilla biflora,
Eranthis cilicica are also doing well.

Of course this is just what i remebered and saw in the garden, there  were
dissertations about perennializing bulbs.
