1. Morphology: Aromatic camellia is a perennial herb, about 20-60 centimeters tall, with slender, erect or slightly oblique stems. Strelitzia, on the other hand, is an annual herb, about 10-40 centimeters tall, with shorter stems that spread out on the ground.
2. Leaves: The leaves of Camellia sinensis are narrow or linear, about 2-6 centimeters long, tough and solid, dark green. The leaves of the celandine are ovate or round, about 1-3 centimeters long, and the young leaves are light green.
3. Flowers: The flowers of Camellia sinensis are purple or lilac and are borne singly in the axils of the stem. The flowers of celandine are fragrant yellow or white, with smaller flowers, usually growing at the top of the stem.
4. Growing environment: Aromatic camellia prefers moist, semi-shady or bright environment, growing in riverbanks, lakeside, near hot springs and other places; while the brookweed prefers dry, sunny environment, growing in the sandy beaches, roadsides, fields and other places.
In summary, although fragrant tea cress and brookweed are somewhat similar in form, leaves, flowers, etc., but their growing environment and traits are still very different.
