Ina, To be honest I never measured Hippeastrum flower size, as far as i can remember, but I know that for sure bulb size has influence on flower size, at least for tulips, lilies, and sometimes in Hippeastrum. I had the common red Hippeastrum (Red Lion, most likely), and the offsets have smaller flowers than the mother bulb. One time i managed to get only one 46/+ sized orange and it had huge flowers, bigger than 20 cm, 3 stems, 4-5 buds/stem. Bulb size also has influence on bud count, and on stem count. But next time if i'll have a flowering sized Hippeastrum i'll measure the bulb and the flower size. Regards, Janos Z5a, Hungary
