How would one describe a "gnarled" tree?

A "gnarled" tree is characterized by its twisted and rugged appearance, often resulting from age, environmental conditions, or growth patterns. Such trees typically have unusually thick, twisted branches and uneven bark, which can convey a sense of resilience and strength. This description captures the essence of what makes a gnarled tree distinct. The other options do not match this description; for example, a straight and elegant tree would suggest a smooth, upright shape, and a young and thriving tree implies vitality and uniformity which contrasts sharply with the ruggedness associated with gnarled trees. Delicate and fragile also contradict the robust nature of gnarled trees, which are often seen as strong and enduring despite their contorted forms.
