My Tennosui pear has not bloomed yet and is going into it’s third year in the ground in my orchard. Note, it’s seed parent variety, Tennessee, is making its first really significant crop of pears this year, and it’s going into its seventh year. The marketing descriptions say that Tennosui starts to bear young, but those are marketing descriptions. Its sister variety, Southern King, which is the same age, put out one cluster of flowers last year but nun this year. Southern King leafs out way earlier than Tennosui and just generally looks different.
Given that mine has not bloomed yet, I can’t speak to its relative bloom time directly, but Tennosui is one of my later pears to leaf out. But it breaks dormancy with and is supposed to bloom with the later common pears such as Orient, Kiefer and Scarlet. This year mine broke dormancy about a week before Orient. Given when my young Korean Giant and grafts of other Asian pears broke dormancy, I doubt that Tennosui will reliably bloom with them here. The Hosui, the pollen parent, is supposedly a little earlier blooming than the other Asian pears, so their might be overlap with daddy.
Clark recently posted a thread about pear flowering times to which I posted a table showing when all my established pear varieties break dormancy, opened first bloom, began main bloom and ended main bloom. I don’t have a category for “last bloom” because low chill pears tend to bloom a flower here and their all through summer and up until frost.
For what it is worth, I absolutely do not think it’s likely that the photo at the top of this thread is a Tennosui pear given all the descriptions and photos I’ve seen of it. God bless.
