I just bought a house from an amazing gardener in her 80's. She planted 6 Yucca harrimaniae on the property as small plants. They are now HUGE- about 2 1/2 feet tall spikes and I'm told the flowers will stand taller. I dug one up to give to a friend to find it was 4 seperate plants with an extensive bulbous root system. I now nothing about these plants. I do know they thrive here in northern Ohio and that is amazing. All I read is that it is a midwestern plant. I have been told they are valuable, which is why I dug one up to give to a friend. I plan on putting several rock gardens in the yard, so I will transplant some to those. Question: How do I move these without damaging the bulbs? It seems, as big as these are, I couldnt dig far enough from the plant without cutting a bulb. Thanks for the info, in advance.

this is a common stemmless Yucca of the Rocky Mountain states that was, along with Yucca glauca, one of my least favorite plants in my youth- got stabbed by them all the time while hiking about the New Mexican mesas and canyons. Bayonet is a good description of this plant, and though I now find it somewhat ornamental, its pugnacity keeps me from giving it a 'thumbs up'.
