A lightening strike couldn't bring this mighty Catalpa down.
It remains sturdy and strong.
Mostly deciduous trees, they typically grow to 12–18 metres (39–59 ft) tall and 6–12 metres (20–39 ft) wide. A 10-year-old sapling will stand about 6 metres (20 ft) tall. They can be recognized by their large, heart-shaped to three-lobed leaves, showy white or yellow flowers in broad panicles, and during the autumn by their 20–50 centimetres (7.9–19.7 in) long fruits, which resemble a slender bean pod, containing numerous small flat seeds, each seed having two thin wings to aid in wind dispersal. Because of the leaves, they are sometimes confused with the tung tree (Vernicia fordii) in the southern U.S., or the invasive Paulownia tomentosa imported from China.
Due to their large leaf size, catalpas are a popular habitat for many birds, providing them good shelter from rain and wind. These trees have few limb droppage, but drop large dark-brown bean pods during late summer. The wood of catalpas is quite soft.
Give your Christmas Cactus bright but indirect light. Keep the plant in a well-lit location (like near a window) away from direct sunlight – too much heat and light can stunt growth and burn the leaves. It should also be away from drafts, heat vents, fireplaces or other sources of hot air.
If it's in a north or east-facing window, you won't have to worry about light. But if it's in a south or west-facing window, diffuse the light with semi-transparent curtains or some other light-diffusing device.
