Every now and again, an amazing plant is discovered. One that seems to have it all - fine landscape attributes, highly ornamental characteristics, easy culture and no negative traits. And when it’s hardy enough for northern yards and gardens, there is cause to celebrate. And yet, for whatever reason, the uptake is slow!
Sometimes beauty and desirability aren’t found in colorful flowers and showy fruit, but rather in rigidity of character, dependable performance, toughness and hardiness. It has one of the most defined silhouettes of any large landscape tree - almost perfectly round or oval, like an enormous lollipop atop a solid trunk, and all without any human intervention at all. It turns a gorgeous yellow in fall, is as low maintenance as a tree can get, and will grow nearly anywhere, from the most demanding city boulevard to your own back yard.
You will bring this tree into your landscape for its shape, so give it lots of room to spread out and be seen. As such, it serves multiple purposes in the landscape; shade, accent, and articulation through its distinctive form. It will tolerate many soil types and conditions, and thrives with minimal care and attention.

|Germination||1. Remove form the ziplock bag and keep the seeds in an paper envelope in the freezer till ready to plant or for the winter. This process, called dry cold stratification, mimics weather conditions outdoors and is necessary for ash seed germination.|
2. Remove the seeds from the refrigerator in mid-April. Fill a seed tray or flat with soilless potting mix and sow the ash seeds on top. Cover with an additional 1/2 inch of potting mix and moisten thoroughly.
3. Set the flat in a sunny, warm room, keeping it moist for the next two weeks. Seeds will germinate and sprout.
Thin the seedlings to 6 inches apart. Transplant them into individual pots full of moist potting soil when they reach heights of 2 inches. (source: ehow.com)
