I have owned my current home for 4 years, but it was built in 79. There were some clumps of daffodils already growing in my yard from previous owners. I noticed they were in large clumps and had limited blooms. When I dug and divided them last summer, both clumps consisted of over 20+ bulbs! Is there any rule of thumb as to how many offsets a daffodil makes per year? I am curious to try and figure out when these bulbs were originally planted, kind of like counting the rings on a tree. I do not know what kind of daffodils they are, but will post some pics when they bloom to see if anyone can identify them.

Thanks in advance for any info.
