Thunderhead grows into a dense, billowing Japanese black pine with thick glossy green needles. Bright pale buds stand out especially strongly in winter, contrasting with the dark crown. Its rounded masses of foliage can develop into a tree almost as broad as tall, so give the specimen enough surrounding space to show its cloud-like form.
