Phyllis, you're going to love Invasion, its a stunner! I've been seeing a lot of baby bulbs right on top of the soil too. Some have even pulled right up while pulling out last years stems. I know its late to be just now pulling out those dead stems, but I leave them till I see sprouts in spring to keep me from digging into the bulbs- I tend to get trowel happy in spring, LOL.
I have some Lilies I need to relocate, and they're really special ones to me that I only have 1 bulb of each, so I'm paranoid about breaking off that growth tip! I had installed a bed around a flowering quince that was already here, and now realize that it suckers so heavily I'm going to need to be able to mow around it. It also has poison ivy that creeps out of the middle of the bush and tries to take over the bed. So I've got 'Ariadne', 'Karen North', 'Silver Chimes, and 'Doeskin' growing among quince suckers and poison ivy- uugggg. And in fall of '08 we had septic work done, and the backhoe invaded that bed. I thought 'Ariadne' and 'Karen North' had been destroyed because they didn't show up last year, but low and behold they're both back this year! So this makes me extra concerned about breaking off the growth tips- I doubt they could take another year of no growth.
