I often leave all grass seed in one contianer. They grow into big nice clump. Contrary to perennials or annuals grass does not fight each other in container and grows as one nice tight clump. Once you ready to trasplant it you can still separate that container into several pieces and plant it that way. I do not start seeds in cells as it is waste of precious space under lights. All my seeds started in 2-4 in pots.

Mexican Feather should have been a dead give away. However I have seen in my area, what looks to be MFG. I doubt if I stopped to ask where they got it they would even know what kind of grass it was. Any dead ringer for MFG? Since I have the seeds, I am going to go ahead and plant them, other wise it would be a waste of money. Still might be ;-) Thanks Grass Guy

Good question jxa44, and good answer by gardengal. Just like in real estate, invasive potential is critical to location, location, location. Nassella tenuissima is not about to be pulled from the market. It is, however, not suitable in ALL locations. It's a very useful grass for certain areas, but with all grasses and plants that re-seed, some locations are not wise for planting. It seems that the term 'invasive' gets thrown around about as much as 'native'. Both are relative to location. Nassella tenuissima is actually a native grass in TX. Of course, seeking plants simply listed as 'native' is not always the answer. Everything is native to someplace, but that place may not be where you live. AND...non-native does not define a plant as invasive either. There are some interesting and surprising plants listed as invasive in some part or other in the US. These include, among others, nandina, euyonymous, butterfly bush, parsley, daylilies, black-eyed Susans and even Japanese maples. Unfortunately, since you didn't list where you're located, it's impossible to answer any question about a plants potential in YOUR area.

The 'dead' is seasonal, and more pronounced in warm climates. It's a cold season grass, which blooms in early summer. The flowers age to a blonde/tan, and the grass will frequently go dormant in the heat of mid to late-summer. Many people like the fluffy tan flowers, and leave them on the plant through the winter. As you weather cools down, it should start another season of growth, and will green up. If you don't like the flowers, you can give it a haircut at the beginning of the cooler weather. It should fill in quickly with new green growth. Trimming it may help to reduce the reseeding this plant is known for. It will quickly naturalize an area in your climate.
