flower and plant genome questions

[Jon Greenberg]

For a high school biology text, can anyone please tell me...

1) some examples of common, easily available flowers with UV-fluorescent
"landing strips"?

2) Which plant gemome(s) are sequenced and available on-line.My
recollection was that either a Marchantia species (which one?) or
Arabidopsis thaliana had been completely sequenced.

Can anyone help with these questions?  Many thanks.
