The post title says it all. Here is the full text of David Griffiths' BULBS FROM SEED, published in June, 1934, as Circular No. 311 of the US Department of Agriculture.
Two of my favorite passages: on page three, he points out that a seedling bed 3 feet by 50 feet can produce about 25,000 plants! That should rejoice the heart of all of you who cherish dreams of a back yard cottage industry. On page 25, he points out that many bulbs need to mature into a drought - I've worked this one into many of the bulb presentations I've given. I think it's one of the most important things to know about bulb culture in our climate.
The plant he mentions as Cyclamen europeum (sic) is almost certainly C. hederifolium.
