FAQs While both are in the Euonymus genus, there are key differences to observe between a spindle tree and a burning bush tree. 'Burning bush, Euonymus alatus, is a bit of a problem for us in North America,' says Bert Bast , garden expert and owner of Bast Brothers Garden Center. 'They are invasive plants that have been known to completely take over unmaintained wooded areas forcing out the native plants that would typically live in that area.
'Burning bush trees are currently banned in Delaware, New York, and Pennsylvania and there is legislation in the works to ban them here in New Jersey. The European spindle tree, Euonymus europaeus, is a versatile and far less vigorous tree,' Bert adds, 'that tends to reach 10-20 feet tall compared with the smaller burning bush, which might only reach 10 feet.' So, while they might look similar, burning bush is to be avoided in the US, as it can quickly spread and take over.

The Korean spindle tree, Euonymus oxyphyllus , is a species of flowering plant in the same family as the burning bush shrub and the European spindle tree.
This species is native to China, North and South Korea and Japan, growing best from US hardiness zone 4 plus. It reaches up to eight feet tall, making it a good choice for a small yard. What's more, the Korean spindle tree also displays remarkable fall foliage and fruits, and it is not considered invasive.
