綠化苗木主要分為行道樹、花灌木、綠籬、草本花卉、草坪等幾大類。實際的綠化中都會采用二到三種以上來進行全部的綠化。
Greening seedlings are mainly divided into street trees, flowering shrubs, hedgerows, herbaceous flowers, lawns and other categories. In the actual greening, more than two to three kinds of greening will be used for all greening.
以公園為例，道路兩旁會植以玉蘭、銀杏、黃金槐、紅楓、香樟等喬木作為行道樹，可觀賞、可遮蔭。行道樹底下會植以、紅葉石楠、金葉女貞、小葉黃楊等綠籬類苗木，用以把道路和花壇隔離開來。
Take the park as an example, Magnolia, ginkgo, yellow locust, red maple, camphor and other trees will be planted on both sides of the road as roadside trees, which can be viewed and shaded. Under the roadside trees, hedge seedlings such as Photinia serrulata, Ligustrum lucidum and Euonymus microphylla will be planted to separate the road from the flower bed.
花壇內可以種植各種花灌木，比如梅花、櫻花、叢生紫荊等觀花灌木，用以賞花之用?；▔锸Ｓ嗟牡乇?，則可以用紅花草、鳶尾、蔥蘭等觀花草本花卉覆蓋，也可以植以麥冬草、四季草等草坪。
Flower beds can be planted with a variety of flowering shrubs, such as plum blossom, cherry blossom, tufted Bauhinia and other ornamental shrubs, for flower appreciation. The rest of the ground cover in the flower bed can be covered with safflower, iris, scallion and other ornamental plants, or planted with Ophiopogon japonicus, four seasons grass and other lawns.
