You can take a look at the description of the Matzke Park Garden on the Monarch Watch website by clicking HERE It also contains a few of the early pictures.
At the time it was registered, the garden had the requisite types and numbers of plants. It might be useful to review a summarized version of the requirements as new plants are considered for the spring. A summary of the requirements are copied at the end of this post.
The full 4 page certification application has much more information and may be found HERE It has a much more extensive list of desireable plants.
