Bracts turning pink with age, as those of Cornus kousa often do.

Do you have these blooming? Please supply more details.

When the pictures were taken, the bracts were this color but a lot of new flowers were just opening near these bracts.

There are two white ones at Quarryhill. They bloomed at a much younger age than anyone had expected.

You might have missed the discussion point between Jujujojo and Bboy. Bboy believes that the white flowers on "white ones" will eventually turn pink and purple as they age. Jujujojo observes that newly developed bracts show pink color on the "pink ones". The question is: are the "pink ones" different from the "white ones", or are they the same in terms of cultivars?

How tall are their two trees at Quarryhill? Are they consistently blooming every year? If not, on average, out of how many years do they have one good blooming year? Do you think certain chemicals in the soil might promote blooming?

floral_uk and campanula might share some thoughts since they have some high profile bloomings recent years.

The ones at Quarryhill never turn pink. They stay white. They have started blooming relatively recently and seem to bloom with regularity. The soil pH is about 6.5. These trees are straight species henryi, grown from seed.

Do you know for how long do they stay in bloom each year?

Sara Malone Zone 9b , thank you so much. Are they blooming this year?
