I started mine 2 years ago from seeds from someone in Arizona. They sprouted easily and grew well but stayed small as they produce a taproot the 1st year. Last spring, 2017, they went into their own 4" pots and the narrow pine-needle-like foliage grew to 6" long. In the fall I put several together in large pots, similar to the way I grow my red variety and they've thrived and grown. They are still too young to bloom as that takes about 5 years from seeds, from my experience with the red ones. They are planted in cactus/succulent potting soil and can take drier conditions, but get watered regularly since they are in pots and not in the ground. I think the yellow flowers will look nice next to the red ones.
