No. Search orange flowers and marigolds, daylilies and poppies come back. Run the same search for orange blossom and your page fills with citrus material and wedding traditions instead. An orange blossom citrus flower takes its name from the tree that grew it, and an orange flower takes its name from the color of its petals. The word orange is doing two jobs there. That one overlap sends you to the wrong page.
English handed the fruit and the color the same name, so you now have one word pointing in two directions. The color was named after the fruit, not the other way round. When a grower says citrus blossom, you are hearing a family label. That phrase points at the tree, not at the color. You learn nothing about shade from it, and nobody checks a color chart before using the term.
An orange flower earns that name a different way. Carotenoids are the pigment group behind yellow, orange and red petals, so you call a bloom orange once the petals carry the right mix of them. The test is chemical. Plant family has nothing to do with the result, which is why your orange flower list runs across unrelated groups that share nothing but a color.
Color words are loose too, which stretches that list wider for you. Carotenoids cover yellow through red, so petals you might call apricot, tawny or almost scarlet all get filed under orange by somebody. A tree name has no such give. The flower either opened on that tree or you are looking at something else, and nobody argues about the shade.
Butterfly weed shows how the color side works in a real bed. NC State Extension describes clusters of bright orange to yellow-orange flowers, with bloom running May to August. The common daylily gives you the other easy example. The species name fulva points at the reddish-yellow, tawny amber cast in those petals. Gardeners named that plant for color in Latin long before you could type the word into a search box.
California poppy belongs on the same list. You get the state flower of California, a plant that grows wild along the Pacific slope from western Oregon down into Baja California. A milkweed, a lily relative and a poppy share next to nothing once you put them in the ground. Each one wants different soil and different care. Color is the only reason you find all three on one page.
Plant lists make the same slip. A page titled orange flowers will hand you a spring bulb next to a shrub, because color was the only filter behind the sort. That helps you build a color scheme and does nothing for you when you need blooms in one specific month. Read past the color word every time, and check bloom season and mature size before you buy.
That is why your two searches feed you such different results. Ask for an orange tree flower and you land on citrus material and bridal traditions, because a search engine reads those words as a tree name. Ask for orange flowers and the results are plant lists sorted by color, thick with daylilies and poppies. Neither answer is wrong. You asked two questions without meaning to. Treat the color word as a starting filter and nothing more.
So pick the phrase that matches what you want back. If you want orange color in a border, type orange flowers into the box, then pin the search down with a season, like orange perennials for late summer. Want the tree itself? Stay with citrus sources under the name orange blossom. One word changes your whole result set.
