The only tulips that come back faithfully every year for me are the Darwin types. But even those, their performance alternate every other year. One year it will be spectacular and the next just ok. It seems like it takes a small new bulb a year or two to build up enough energy to bloom. Most of the other types just never come back. I think the reason is they are more susceptible to rot during the summer dormant stage. If you dig them up and replant them, then they will be OK. But that is just too much hassle and work to do every year.
Mary, the crocus will still grow if the bulbs happen to fall upside down? Thanks for this tip. If they don't mind the orientation, then I will just make it easier on me by just scattering them in the soil instead of planting one by one.
