Not all whites are the same, nor are all reds. In my backyard I've aimed to have a white garden, but some of the flowers are more ivory/cream while others are white-white (more of a stark contrast). But that doesn't bother me, but if you were trying to go with the house trim or something, this might influence your decision. I got Ruby Vigorosa roses for my front yard thinking they were going to be red-red, veering toward the orangy red. Well, with the heat those suckers are dark pink (and in lots of heat, actually fade to pale pink). But in winter they're such a dark-dark pink that they go for pale red. Sometimes it really is better to see a rose in your local environment then having to trust pictures and people on the phone to describe a color. Just my two cents.

Yes crabapples can and are used to pollinate apple trees. The resulting fruit will always be the same variety as the mother tree and the seeds will actually be a hybrid of the two parents. Since we do not eat the seeds this works perfectly fine. Many large scale commercial orchards have used crabapples in the past to pollinate large fields of a single apple variety . Many commercial apple tree sources still grow and offer some ornamental crabs for this purpose. The home grower can use them too for pollination if needed assuming the crabapple bloom overlaps enough with the apple variety you are growing for good pollination (usually they do). Most crabs on the market are ornamental (have small fruit) but some really good larger fruited crabs do exist (Whitney, Centennial, Chestnut ect). My experience with large fruited crabapples is that they do not store well and get soft quickly. They can be excellent to eat fresh when picked at the peak of perfection. I canned many a jar of pickled whitney crabapples in my youth. The sweetest crab I have ever eaten is Trail which is yellow fruited. Very popular in the Dakotas and Northern Minnesota. Almost too sweet but definitely delicious.

It's not in the budget to update the other windows with black frames. I will go with a white frame for the folding door if that will look best. Another option is a wood frame around the folding door. That would actually match our front door. Would that option work? Or would a white frame still fit the best?

We are refinishing our shaker cabinets in a small lower level kitchen area. We'll be leaving the cabinet handles under the sink where they were (vertical placement), but we're adding this edge pull handle to the right side (garbage pull out), on the top edge of the door: Amazon.com: Richelieu Hardware BP989819230 Lincoln Collection 7 9/16-in (192 mm) Center, Contemporary Edge Pull, White : Everything Else
