Here are some other choices you may want to look at.
Maple, Dwarf Vine
Daphne odora 'Aureomarginata' - Daphne, Winter Variegated
Disanthus cercidifolius - Redbud Hazel
Fuchsia erecta - Fuchsia, Hardy: Not all fuchsia are hardy in your
zone but some are so it has to be these particular types.
Fuchsia magellanica 'Riccartonii' - Fuchsia, Hardy
Common Mallow
Kerria japonica 'Chiba Gold' - Kerria
Mahonia aquifolium - Oregon Grape: These are aggressive growers so a root barrier would be a really good idea. But if you want to make the best jam in the world every fall this is the
plant you want.
Well this should give you some to take a look at. If none of these are what you are looking for let me know and I'll see what else I can find that might be better suited. Could you tell me which
growing zone you are in? That would help me some. I'm figuring either 5 or 6 but boy could I be wrong lol. Good luck with your search.
