Make It Green Garden Center

Welcome to our plant search tool. This database contains many of the thousands of plants that we carry. There are some notable exceptions. Hundreds of new perennials come out every year and Make It Green has been a leader in making them available to you. Eventually the recent introductions will make it to our plant search tool but every year there will be a lag between our in-store plant selection and this search tool. Unfortunately this search tool can't cover everything that we will carry this year. We also carry over 100 varieties of rare and unusual evergreens and over 100 varieties of hard-to-find shrubs many of which are not in the plant search. Click on the Plant List button for a list of nearly all the woody plants (trees, shrubs and evergreens) that we have ordered or already have in stock for this coming year.

Description:

An extremely hardy small tree for difficult wet sites; no particularly striking ornamental features, but generally a neat, clean choice for landscape purposes

Ornamental Features

Mountain Alder has forest green foliage throughout the season. The oval leaves turn yellow in fall. Neither the flowers nor the fruit are ornamentally significant.

Landscape Attributes

Mountain Alder is a deciduous tree with an upright spreading habit of growth. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This is a relatively low maintenance tree, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.

Mountain Alder is recommended for the following landscape applications;

  • Shade
  • Naturalizing And Woodland Gardens

Planting & Growing

Mountain Alder will grow to be about 30 feet tall at maturity, with a spread of 25 feet. It has a low canopy with a typical clearance of 5 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 60 years or more.

This tree performs well in both full sun and full shade. It is an amazingly adaptable plant, tolerating both dry conditions and even some standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is native to parts of North America.
