|The characteristic blunt leaf of the Liriodendron|
'Liriodendron' means lily tree and 'tulipifera' means tulip-making, both in relation to the large-ish, single flower – as you might expect from a member of the magnolia family. So tulip tree is a much more appropriate common name. Unfortunately, you're unlikely to see this attractive green and yellow or orange tulip-y bloom until the tree is about 15 years old, or 20 feet/6.5 meters tall – and, even then, they often appear near the top of the tree, where it's hard to appreciate their form. Unless you're a bee. Tulip trees are very attractive to bees.

This is a fairly adaptable tree when it comes to growing conditions and climate. In Southern Ontario, we're at the northern limit of its native zone, which stretches all the way down the eastern continent to Florida. I've seen it listed as both shade-intolerant and somewhat shade tolerant, so I suspect culture has an impact on this. Like many of the most attractive forest dwellers, tulip tree does best in deep, rich, moist, slightly acidic soil, where it can grow to a significant size fairly rapidly.
