Chinese tulip tree is a fast-growing, columnar tree that typically grows to 50-70’ tall. It is named for its cup-shaped, tulip-like flowers (same family as magnolias) that bloom in late spring to early summer. This tree is very similar to Liriodendron tulipifera (native to eastern North America), except it is denser, slightly smaller, has smaller flowers without orange banding, has more deeply lobed leaves and is not as cold hardy. Cup-shaped flowers (to 1.5” long) are olive green with yellow at the base. Flowers begin blooming in May. Flowers can go unnoticed on large trees because the flowers appear after the leaves are fully developed. Sometimes the flowers are first noticed when the attractive petals begin to fall to the ground. Flowers are followed by dry, scaly, oblong, cone-shaped, brown fruit clusters, each bearing numerous winged seeds. Clusters disintegrate when ripe. Lobed bright green leaves turn golden yellow in fall. Genus name comes from Greek leirion (lily) and dendron (tree). (info source: missouribotanicalgarden.org)

|Germination||1. You should count how many seedlings you want and buy seeds accordingly - even in the nature seeds have a very low germination rate.|
2. Stratify the seeds. Wrap the seeds in moist paper towels, and place the packets of seeds into small plastic bags. Place the bags into the refrigerator for eight to twelve weeks. Check on them weekly once you reach the initial eight week period, and remove any seeds that have sprouted.
3. Prepare the containers for the seeds. Tulip poplars have very long taproots, and require containers that are very deep. Fill the containers with nutrient rich potting soil.
4. Plant the seeds. Dig out small depressions no more than a half an inch deep and insert one seed per hole. Water them in well, but do not allow the soil to become boggy. Place the container in a sunny location.
5. Assess the seedlings. The tulip poplar seedling can be transplanted once they grow a set of true leaves after the seed leaves. Exercise caution when transplanting the seedlings, as any damage to the taproot could cause the tree to die. (info source: eHow.com)
