Edie...Funny story...last summer, Sean had some buddies over for a swim. His friends know where Sean's plant collection is--grouped together near the house by the pool. One of the guys decided to be a smart a--, and grabbed one of the smaller cacti in a pot and yelled to another guy in the pool, "let's play keep away from Sean...". Now mind you, these were all baseball players with pretty good arms... One of the other 'new' guys said "hey..throw it here" (he was in the pool-not knowing what kind of plant it was). Sean just stood there shaking his head and told them I don't think you want to do that...the kid threw the plant to the other kid, and he caught it mid-air about 30 feet away---along with a handful of thorns!!! OUCH!!!! I'll never forget the scream! Sean said "they'll never touch my plants again!!!" Yes, boys will be boys...

Frmmi, yes I may be interested in your coldframe. How big is it? What city are you in? Palmlover, a robusta would not survive in zone 6 without a heat source, even if it were heavily mulched. I can't even get my basjoos to come back from the roots in zone 6 even if they are heavily mulched. My windmill survives because it is a zone 7b palm, while a robusta is a zone 9 palm. Any palm in a pot in zone 6 would also need a heat source to survive. If the roots are frozen, like Jimhardy mentioned, then they can't take up water and will die. You're best off bringing the pot inside for the winter, or at least into a garage with windows.

fourpaws, I'm glad you're back, too. Follow ups really help tune up these forums. Would you mind taking a picture of your faux lawn from an altitude of about 6 inches, so we might be able to identify the ground cover plant(s) you have? The best time to take a pic is when it's cloudy or overcast, so the Sun isn't casting shadows into the grass. Also it would really help to know where you live, not your USDA Hardiness Zone, but your zip code or the name of the nearest community. It might be that the plants you have are limited to certain soil or climate conditions and not be suitable for others. gg, I believe this forum has a successful record of adapting to the homeowner's preferences. If someone wants the yard of the month, we can help. If someone wants a mix of grassy ground covers to keep the mud off their floors, we can help with that, too. Back in the early 2000s the members here could be a little rigid with their help. I believe what morpheuspa was referring to in his first reply to fourpaws was that he/she did not have a lawn problem, and the primary reason for this forum is to help solve problems. You and morph feuded for years, and you still can't let it go even though he's gone. Really?
