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.

Planting & Growing
Giant Japanese Butterbur will grow to be about 4 feet tall at maturity, with a spread of 5 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 4 feet apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
This plant does best in full sun to partial shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
