Raspberry Honeysuckle (Lonicera harae)
Here is my single L. harae specimen. Note the indumentum on the leaves which is not present or unremarkable with more common species such as L. caerulea or L. japonica.
The plant in whole. Seems to be well-suited to temperate climatic zones. I’m from the UK in what would be the equivalent of roughly USDA hardiness zone 8. I can’t imagine this to be a finicky plant to grow.
Below is some information I have compiled mainly from Korean academic articles. Information is not commonly available for this species. I’m certain that foragers in the native ranges know much more about this species than is available online. I could not find any sources whether L. harae is self-fertile or not. If not, it’s possible it could be pollinated by other species, most probably by L. fragrantissima.
L. harae fruit would appear to be edible and safe for humans AFAIK. Jurassic Plants Nurseries here in the UK certainly say so, and they are very knowledgeable with edible plants. They are using the common name ‘raspberry honeysuckle’. Some Korean papers did discuss it being used as a food source.
Family: Caprifoliaceae
Publication: Originally described in 1914 by Tomitaro Makino in the Botanical Magazine, Tokyo (Vol. 28: 123).
Native Range:
- Japan
- Korean peninsula
- Likely Southeastern China
- Possibly Russian Far East also
Germination:
- Optimum temperature for seed germination is reported to be 20°C. That’s 68°F for Americans
Phylogenetic Analysis:
- Forms a clade with Lonicera fragrantissima.
- Phylogenetically positioned with L. fragrantissima and L. hispida within the subgenus Chamaecerasus, section Isica.
- Found in Southern Korean Peninsula, Jeju Island (Korea), Tsushima Island (Japan), and parts of Southeastern China.
Uses:
- Appears to be used as a natural flavouring substance.
- The fruit serves as a food source (Son et al. 2021).
Morphology:
- Highly similar to Lonicera fragrantissima, which is endemic to China.
- Differentiated mainly by flower colour and leaf hair type (Ohwi 1965; Yang et al. 2011).
- Close relationship confirmed by Nakaji et al. (2015).
Hopefully my formatting here has worked correctly!
