I have absolute gobs of what I think is GoldMoss sedum. Some was given to me by a friend a long time ago, and I have worked on making it cover a large area(it is excellent). Since it was given to me, I can't be sure of the actual name of this sedum, but it looks the same to me as GoldMoss--it is just a few inches high, easy to propagate even by ripping off tops and mixing in soil, and has small yellow flowers right now. I would love some allium if you are interested--let me know about quantity, etc.

I have had the same ground cover roses (about 15 bushes) covering a strip in front of our house between the sidewalk and the street for 15 years. The area is about 4-5 feet wide and 60 feet long. I have always pruned them once a year with electric hedge clippers - it only takes about 20 minutes. They are thriving, and bloom all Spring & Summer, starting about now. You are in a completely different climate than we are, so I cannot comment on timing re transplanting, except that here we try to do that when the roses are as dormant as they are going to get (here some of them never go dormant). Of course, you will have to worry about frozen ground, etc. Re when to prune - I have discovered after two decades of experience that it really does not matter much when you prune, as long as you do not prune at all when the roses are just babies trying to get established (and in your climate probably not in the Fall when the new growth would get frozen). So, go for it! Don't forget to feed them. Jackie

Michelle I dont know if I can answer this right, but looking at my Carpet Roses . Pink Bassino, Red Bassino, Sea Foam, and My Rosy Carpet they are a mass of flowers and I honestly think that they will only spread to the width they are suppposed to and thats it, but I find that Lavender Dream that came with a ground cover label on it is shooting up so much higher and wider than those four, but it is a bigger size one. It the plant is only suppose to grow say 80 cms High X 1.5cm Wide I dont think it will grow much wider, by cutting off those high canes skyward canes I dont know if it will make them grow any wider either but I honestly dont think it will . I am sure one of the experts will be along soon to let you know..Cheers..MM.

it depends on the type of groundcover. Some are very aggressive and will spread rampantly - others are very tame :-) I can't see clearly what it is you are growing but most mat-like groundcovers are not the slightest bit aggressive. I wouldn't worry. They are also less effective at controlling weeds. And any groundcover will do nothing for the horsetails (which I don't see in your photos, btw). Nothing will stop them.
