I haven't tried these myself, but perhaps Rosalind (Illyria, Dew-covered berries and fresh green grasses with a faint breath of spring flowers) or Squirting Cucumber (Rappaccini's Garden, A spurt of wet, grassy greenness) would be what you're looking for.
As for how to order from the UK, we have to use PayPal! There's a helpful thread on it here.
