I’ve actually had Rubus odoratus, or flowering raspberry, in my garden for a few years now and I've found it to be a really rewarding plant. It is indeed quite low maintenance, which is always a bonus when you're juggling different varieties in a single space. One of the things I love about it is its adaptability to different light conditions. In my garden, it thrives in partial shade; it actually appreciates not being in direct sun all day, especially during the hottest parts of the afternoon.
As for interactions with surrounding plants, I haven’t found it to be overly aggressive, but it does have a tendency to spread. It’s not nearly as invasive as some other Rubus species, but it’s wise to give it enough space to spread out a bit. A good tip is to monitor its growth annually and prune as needed to maintain its shape and prevent it from crowding neighboring plants.
Regarding pollinators, you’ll likely find that flowering raspberry attracts a fair bit of attention. In my experience, it's a magnet for bees, particularly bumblebees, which are drawn to its blossoms. Butterflies also seem to enjoy it, making it a lovely addition if you're hoping to encourage more activity in your garden. Since pollinators are so crucial to a healthy ecosystem, adding plants like these can really make a difference.
Do keep in mind that while it isn’t fussy, the flowering raspberry does best with a decent layer of mulch to conserve moisture and keep the roots cool, especially in areas where summers can be dry. This also helps control weeds naturally.
If you're looking to add a visually unique and wildlife-friendly shrub to your garden, I think you’d be quite pleased with Rubus odoratus. Have you considered how you might integrate it with other shade-tolerant plants in your garden? Feel free to ask if you’d like suggestions on companion plants, or if you have any other questions!
