just a thought i dont have time to look up ...

is it a heavy reseeder .. and do such seeds have access to the lake??? ... its bad enough if you create your own problem.. if any .. but you need to be sure the seed doesnt float down wind.. and make problems for others ..

again.. im speculating ... im sure someone will set us straight ....

I would love to hear an answer on this. I bought a packet of seeds and it's windy here also.

My only experience with Love Lies Bleeding in my zone 6b New York garden, is that it takes a longer season to attain any size than is possible here. I had a beautiful one that I bought as a gallon plant one summer, but subsequent attempts to grow it from seed yielded miniature plants in August. I don’t see your zone but splurge on good size plants if you need to.

Ken, I hadn't thought of that. I was looking forward to harvesting both the leaves and seed. I just did a quick google and it doesn't seem to be invasive, but maybe I'm just not finding the right info. I'll keep looking.

I'm in zone 3 so it might not even be an option. I was going to start it from seed this week, but I wonder if that will even give it enough time to get to the flowering stage. Hmmm. I might just try it but have a back up as well.

Other thoughts on a show stopper that will cascade over our kind of ugly rock wall and not be deterred by the wind? I am planning on creeping jenny, but would also like something with colour.

ETA: I know creeping jenny/moneywort can be invasive, but our summers are too hot dry for it. I've had it in 3 or 4 different gardens and while it spreads to cover small areas in a garden bed, it doesn't move outside of the borders or the garden or pot.

Some of the clematis can be nice if you grow them up, not down. And they're actually fairly happy to cascade down if you...well, push them over the cliff, so to speak. The same is true of honeysuckle, and other blooming vines. The lake may moderate your temperatures enough that zone 3 has a microclime for your house. Clematis is a weak climber, so won't get grabby and might object to winds.

Morning glory is not a weak climber and holds on quite well, thanks. It tends to grow up, not down, again, though. Without photos, I can't tell if it could be planted at the bottom, but might be worth a shot. Choose an early bloomer; the latest blooming ones barely go in October even here in Zone 6b/7a.

The wave petunia can get downright cascady and look great in low pots on walls. Look for larger varieties that tend to do this. Petunia don't give much of a care about much of anything. :-)

You might want to look for golden creeping Jenny for some color--it's kind of unique.

Scaveola can be a nice annual in some places. I used it at my old condo and it trailed from its pot right down to the floor of my deck and below it. It generated some complains from my HOA, too, because that's a rules violation. :-)

And for a quick chartreuse, the sweet potato vine. Easy, breezy, and very, very greeny-yellow.
