Eucalyptuses or Eucalypti?

I made this design just so I could say eucalypti! This one is a mixture of two different types of eucalyptus tree parts.

In the 1850s, Eucalyptus trees were introduced to California by Australians during the California Gold Rush and became America's Largest Weed.

Eucalyptus corymbia ficifolia or Red Flowering Gum makes up the center circle in the spectacularly colored buds, and the leaves and partially opened buds are like the clanger of the bell shape.

The quite common leaves and small blossoms of Eucalyptus Globulus or Blue Gum Tree grace the corner frames.
