Keystone Value: The Alnus (Alder) genus supports over 200 species of butterfly and moth caterpillars, providing food for a variety of birds and mammals.

Tag alder is a multi-stemmed large shrub, which does great if planted in a moist, mucky spot. In the wild they grow in bogs, ditches, wetlands, and swamps, typically reaching 10-20′ in height. In spring they develop attractive drooping catkins, which give way to small cones, which are desirable to birds. Tolerates poor soils and can even fix nitrogen. Alders are attractive and functional shrubs with high wildlife value, which tend to be under-utilized in gardens. They provide cover to small mammals, which also eat the twigs and foliage, and various birds such as goldfinches and redpolls eat the seeds, buds, and catkins.

At Direct Native Plants, we take many precautions to make sure your plants will arrive in the best condition possible.

Our perennials are grown in a 4” quart-sized pot. These plants are then cut back to fit our packaging, placed in a protective clamshell container (made from recycled materials), and then shipped to you in a cardboard box.

Trees and shrubs are grown in a 7” tall container (referred to as a 1-gallon pot), and depending on the species will be between 12” and 36”. We bag the root section of these plants to prevent them from drying out in transit and ship them in a tall cardboard box. PLEASE NOTE: These boxes can be shipped in bundles up to 6. After that we start a new package, so keep this in mind if you’re trying to get the best shipping rates.

Direct Native Plants supports the United States Postal Service, so your plants will ship via USPS Priority Mail. Orders ship out Monday through Wednesday of each week, and depending on how close you are to our nursery in Maryland, shipping will take anywhere from 1-4 business days.
