Cherry plum (Prunus cerasifera). Purple-leaved forms and hybrids of this also abundant. Sometimes the white will be coming out from the bottom of the pink-and-purple purple-leaved plums. Elsewhere it may have gotten onto a site as rootstock for orchard fruits trees instead of ornamental, it may have been planted for its own fruits, or it may have come up from seed.

I've got cherry plum rootstock sprouts coming out from underneath Japanese apricot (P. mume) cultivars; I need to get these sawn off this year as they have gotten big enough to flower. Japanese apricot is the most choice ornamental stone fruit and it appears the unimpeded development of the cherry plum rootstock sprouts may be starting to affect the vigor of the Japanese apricot scions.

I frequently see pink-flowering cherries with branches of white flowers, from the rootstock sprouts that didnt' get pruned off.

Yoshino cherry is white flowered and early blooming, and pretty common here in Oly. The native wild cherries are white flowered also, but more like shrubs than trees, and rarely planted in gardens. Seedling cherries, so-called bird cherries, are white flowered but not quite blooming yet.

The locally prevalent native cherry is bitter cherry (Prunus emarginata). It produces inconspicuous tufted dull white flowers during May - often against the leaves. While some here are shrubby the common mode locally is a slender single-trunked tree. Like other cherries it is a sun-loving pioneer species and in our area often develops noticeable gummosis on the trunks after a time. Most die before without breaking out of the small tree size category. One in Seattle's Seward Park managed to get 100' tall before petering out.

The sweet cherry (P. avium) referred to above as bird cherry (also used for other species) is a quite common weed tree in this area. Many will assume it is a native tree as there are so many scattered about on undeveloped land in local communities. Interestingly, it crosses with the genuinely native bitter cherry to produce a not uncommon intermediate hybrid that has been named Puget cherry (P. x pugetensis) and described botanically by Seattleites A.L. Jacobson and P. Zika.

There's another possibility - the flowering pears are starting to bloom. Upright growth habit, white flowers, around here they're interplanted with flowering cherries and plums along many of the major streets. Early bloomers although usually a bit later than the earliest plums and Yoshino cherries.

The common ones are Callery pear cultivars with conical or nearly columnar crown outlines and the same malodorous flowers produced by orchard pear trees.

I also stand by the thought that they could be flowering pears. Down here in S. Oregon they bloom same time as the Thundercloud plums that are everywhere, with the maples immediately after. If you can, take a whiff. Flowering pears have an off-putting scent to them.

My flowering Cherry is not blooming yet but my six(6) Asian Pears are in full bloom. Now if the Mason Bees will wake up and exit their Tubes I'll be Happy.

Bought a little tiny Lapins cherry tree last spring at Portland Nursery, and it has grown so much! In 1 year the leader is higher than our roof. It has beautiful white blossoms now. So this weekend we went and bought a Stella to keep it company and help pollinate it. Both the Lapins and Stella are self-pollinating cherry trees but if they're near each other they produce a heavier crop. These are super dark sweet big luscious cherries.

The Stella is too small to have blossoms this year. Hoping it zooms up as fast as the Lapins.

We read from several sources that a bird's favorite tree, in general, is a cherry tree and since we have Mecca for Birds here we figured gotta have cherries!

These are semi-dwarves so we'll net portions off so we get some cherries too.

Lots of fruit trees in bloom now, very pretty. Seeing lots of busy winged pollinators.

Having a weeping crabapple about to blossom.
