I have two CdD Blanche trees, now into their fifth season of growth. It is, by a good margin, the best tasting fig I've ever eaten, though I expect some challenges to the crown as some of my other "premium" figs should begin producing for me this year. Beyond taste, my impressions of this fig are as follows:
A slow grower. CdDB #1, the tallest, remained a single trunk until this year, though it appears that it will branch for me this season. It grew a whopping 12ish inches last year and is 2' tall. It produced 8-10 fruits last year. CdDB #2 is about 16" tall, but split into three branches at about the 8" mark. It put out a 10" shoot from about 1" above the the base of the trunk last year, which I pruned and traded. The three branches grew maybe 4" last season but produced 15 fruits - tremendous production for such a small tree.
Both trees began production in season 3, providing three fruits between them, neither of which ripened fully before the cold weather hit in early November, though they still tasted good enough that I understood all the raves. In season 4 they produced as stated above - well for such small trees. They began ripening fruit in mid September and were finished by the end of October, which was pretty early around here for a fig considered late season. My growing season is fairly short with frost dates of May 15 and ~Sept 15 though it was longer last year than usual. It is, however, sunny and hot between June and mid Sept with temps generally in the mid 80s and 90s throughout that time. I do the fig shuffle for a 8-10 weeks as necessary between mid March and the beginning of June, when I set them out in their summer positions. They get half-day afternoon sun during the shuffle and full day sun in their summer spot.
I started CdD Noir from a cutting last season and it grew much better than CdDB, hitting 18" by the end of the season. I picked up the cutting from a CRFG scion exchange in Sacramento, so I assume the cuttings came from Davis, though they may have come from a tree in San Jose that, itself, originally came from Davis stock. I won't be able to verify if it is actually CdDN until if fruits, hopefully this season, but the leaves are the same as CdDB and the CRFG folks generally have their stuff together, so I have no reason to doubt the authenticity of the cutting.
CdDB from UCD may be a difficult variety in the northeast due to the short season and the comparatively (to Reno) cool and wet summers, but it can produce well in a short season climate with abundant heat and sun. Now, if I can actually get it to grow at least one foot per season on more than one branch and have that be a branch I want to keep, I'll be able to recommend it unconditionally.
