My seed grown leatherleaf is looking good...about 5th yr from seed. I planted it in this location to ramble thur my big oak leaf hydrangea but unfortunately the hydragea died in last summer's heat and drought
Maybe we all have good luck with some plants and don't do well with others. Ours enjoy a lot of manure and compost along with 3" of mulch to keep the roots cool. I add reconstituted water crystals when planting them and then they always have access to water.
I have this species growing on my fence here in zone 4 and it's been doing well for about 5 years. It's a bit too early to say how prolific it will be this year, but it went wild last year. I've never heard the term leather-leaf before. Any stories behind that?
Princess Diana is a hybrid. I have both on my fence and I think Diana is more prolific than the species. Having said that, please remember these plants received no care for the past four years. It will be interesting to see if the species blooms more this year after some TLC.
I'd love to have some of the hybrids w/ big blooms but some how I kill everyone of them. I have a couple more natives...c.viriona and c.fremontii(?will have to check that spelling)I grew from seed but they're not quite big enough to go out in the ground yet. The one I wished I didn't have...or could get under control,is sweet autumn. It re-seeds everywhere. I try to get it cut back after bloom season before seeds are shed but I still find seedlings in everything.
Do you think it's the heat where you live? Maybe if you tried some of the more shade loving vines. I'm planting Silver Moon this year next to Claire de Lune which has been limping along for the past several years on the north side of my garage. The area only gets a few hours of sun. This year the Claire de Lune looks better so I think it just takes some time for it to get going. Both plants are suppose to tolerate some shade.
Sweet Autumn has that reputation. I'm surprised it's legal in Arizona. Another small flowered clematis that might do well for you is Engelina or My Angel.
I would keep on trying to find a large flowered clematis. They are just so worth suffering for. You could email Debbie at Silver Star and ask for some advice. She might know of a few that are heat tolerant.
