Anyone know where to purchase this currently?

I bought Raspberry Kiss at Lowe's/HD abt 3 yrs ago; it's planted on a relatively remote part of the property, so has received minimal care. Beyond the usually cited specs, however, it has grown overtop a 7 foot high trellis and has spread laterally ~15 feet. The thorns are vicious but the reward is an outrageous display, year-round, of blossoms, regardless of watering or fertilizer. I am located on the Kona coast of the Big Island of Hawai'i. Will post pic when next i'm near the plant.

This is my first Hulthemia hybrid, bought in 2018. The foliage is simply luscious. I think I'd grow it for this alone but the flowers are quite charming. The scent reminds me of wild roses with a little added spice. I've since bought another three varieties. Oh dear! Just what I needed - another collection.

So like mentioned in previous comments by others, it produces a lot of hips and seed...germination for me however has been extremely poor (at best 5% territory).

I'll need to check when flowering starts up again if it's pollen is uniform or not. I can't rule out this rose being triploid which may explain it's high rate of dud seed. Given the similar lineage with Blue For You which is triploid and the pollen parent of this rose could easily be a dip or trip from the known info.
