RIGHT. We need house names, and I think we got the go-ahead for our two houses, Foxglove and Wisteria.

Griffyndor House suggestions: Borage, Fennel, Elderflower, Gladiolus, Oak.
Slytherin House suggestions: Begonia, Witch-hazel, Camellia, Cypress, Laurel. (Fungus or Wormwood, whilst having meanings that aren't tied with the house, are also options.
Foxglove...I think the multi-tailed fox is a given, now. So running with the theme of mythical creatures,
Wisteria (Hufflepuff): something hardworking and patient. Perhaps a winged horse, or a hippogriff, as they seem to be methods of transport and the horses actually pull carriages?
Griffyndor house: a phoenix seems like the best idea so far, but there's also a dragon that would work.
Slytherin house: An augery could work (their song was rumoured to predict death), or a Thestral.
If you could pick the best names for each house and the best mascots, we should be able to decide, but if you really despise all of them then feel free to make up your own.
