Red Buckeye is Aesculus pavia

Our Red Buckeye - Aesculus pavia is budding and leafing out today. Gorgeous in its third or fourth year. 

It's a part-shade understory shrub or bush that is native in our area. Can you see it to the left of the daffodils?

Introduction: Red buckeye, a native of the southeastern United States that produces brilliant red flowers, is the best buckeye for this region. It can be grown in all soil textures and is nearly pest-free. Its flowers, which last several weeks in spring, attract hummingbirds and butterflies.
 
Culture: Red buckeye can be grown in shade or full sun, although its growth is shrubby and open in shade. It does well in all soil textures, and prefers a moist, well-drained soil that is slightly alkaline to acidic. It grows best in good, rich soil. It is moderately drought-tolerant and, if grown in full sun, should be mulched and watered to keep the roots cool and moist. Red buckeye, which is hardy in Zones 4 to 8, is almost pest-free, although it can have severe problems with leaf blotch. Related species: There are two plants closely related to red buckeye. Common horsechestnut (A. hippocastanum) is its European counterpart and red horsechestnut (Aesculus x carnea) is a hybrid that resulted from a cross between red buckeye (A. pavia) and common horsechestnut (A. hippocastanum).
