I read somewhere that the
seeds were very small, too. The
plants I have are store-bought (from Lowe's, whose premium
plants have always done very well for me), so I haven't seen any of the
seeds yet. Next year I'm going to try and start them from
seeds.
The
flowers don't seem to be fragrant - it's hard to tell because they are next to my gardenias, which are in full bloom (yee-ha!) and a huge Confederate jasmine vine, also in full bloom, the whole yard is so heavy with scent it's almost intoxicating.
One negative thing about lisianthus is that they seem to be
very fragile. I made the mistake of using overhead irrigation and it beat down two of the
plants so bad they almost died, but they are making a comeback.
They sure do produce lots of long-lasting
flowers, though.
