Is Mrs. Tendo's name never given in the series?

If not, does somebody who's good with Japanese and Flowers know,

a) A short lived, yet beautiful flower?

b) The Japanese name for the said flower?

I need to name her, and I'm not going to just randomly 
choose a name... So, if anybody can help me, please e-mail
me...

Sorry for the spam...
