Hemisphere is a really unexciting geometrical name for what is an exhilaratingly exciting tulip. There is no rhyme nor reason to whether a particular flower will emerge a solid, deep rose pink or white with Jackson Pollock style pink splatter or feathered delicately in calligraphic rose brushstrokes or just mottled slightly with an apple blossom pink hue. It is almost impossible to define the flowering behaviour of this tulip, not least because each bloom evolves and darkens from rose-pink to cerise over its lifetime. It is utterly fascinating, terribly pretty and sheer bliss to observe.
The playful nature of the Hemisphere tulip will be immediately apparent. A mass of these flowers is the floral equivalent of an orchestra with its deep tones of blazing brass to the tiny high pitched tinkles of the triangle. Grow it alone for full effect with planters full of its feminine frippery. If you must dilute it the pure monotone of White Dream would work well or the deep purple of Negrita. and set them all against the dark green background of clipped yew or box or holly.
It was using two hemispheres of copper in Magdeburg that scientists learnt about the effects of atmospheric pressure. Once the two halves were sealed tightly together, the air was pumped out of them to create a vacuum. Even horses were unable to pull them apart because atmospheric pressure held them together.
