yes to question 2, unless you know the particular species clone. Some species have registered names. I have a species (of John's which has a number) so it was I. aphylla 87J X a bearded seedling. Any old species seed out of the wild would just say I. aphylla.
yes to question one as well. John's MTB Billie the Brownie X bee. We have a suspecion of the pollen parent so it is Blue Twinkle X unknown (possibly Spanish Coins.) The latter was in the same bed & the only yellow MTB we grew at that time. 'Billie' won the Williamson-White Medal.
