- Bell's honeysuckle (Lonicera x bella) and Tartarian honeysuckle (L. tartarica) look quite similar. Tatarian honeysuckle has pink flowers and lacks hairs on the undersides of the leaves. Bell's honeysuckle has pink to white flowers and has hairs on the undersides of the leaves. Morrow's honeysuckle flowers are white and the leaf undersides are hairy. It can be extremely difficult to distinguish between Morrow's and Bell's when the plants are in not in flower.
- Amur honeysuckle (L. maackii), Dwarf honeysuckle (L. xylosteum) also look similar, especially when not in flower.
- Native honeysuckles have solid stems, while non-native honeysuckles have hollow stems.
- Used as an ornamental in the landscape, Morrow's Honeysuckle quickly escaped cultivation. Its seeds are dispersed by birds that consume the red fruits. It creates dense stands and shades out natives. Lonicera morrowii can hybridize with L. tatarica to form the hybrid Lonicera x bella, also an extremely invasive plant.
