Hosta 在我们北方很常见,沿着树桩围一圈,还挺好的,几乎不用管,年年生。 狗了一下发现更多品种。 Plants for use under trees: Some of the best truly tough perennials for this type situation are Hosta, Vinca major, Heuchera, Lamium and Sweet woodruff. There is nice summary article from OSU on shade perennials at this website: http://ohioline.osu.edu/hyg-fact/1000/1242.html. There are lots of great shade perennials, but you will really need to focus more on the watering and fertilizing and mulching. If you are maintaining this, the rest should be relatively easy. From the Proven Winners perennials line I would look for the following plants: Pink Chablis® Lamium, Pulmonaria Gaelic® Spring, Black Scallop Ajuga, Dolce® Heuchera, also look into Columbine of any type as they have a tap root and get deep roots down pretty quickly, though they are only spring blooming. For fall try adding a selection of fall blooming asters such as Sapphire, they are tough and durable but only flower in the fall. All these plants are searchable on our website; just put the name into the quick search box and you can look more closely at each plant. Remember that the area under or very near trees and shrubs is a highly competitive area where the roots of the trees are stealing all the water and fertilizer from the plants below. So you need to compensate for this.
