Del, I've had trouble propagating Crandall also, but recently found a Plants for the Future page on Ribes odoratum (see http://www.ibiblio.org/pfaf/cgi-bin/arr_html?Ribes+odoratum), that gives the following propagating advice (Lacking a mist system as Lon has, I hope to try sticking some half-ripe cuttings in July or August this year.) -- Sam Brungardt, St. Paul, Minn. (USDA Zone 4b):
Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold frame. Stored
seed requires 3 months cold stratification at between 0 and 5° C and should be
sown as early in the year as possible[113, 164]. Under normal storage conditions
the seed can remain viable for 17 years or more. Prick out the seedlings into
individual pots when they are large enough to handle and grow them on in a cold
frame for their first winter, planting them out in late spring of the following
year.
Cuttings of half-ripe wood, 10-15 cm with a heel, July/August in a
frame[78, 113].
Cuttings of mature wood of the current year's growth,
preferably with a heel of the previous year's growth, November to February in a
cold frame or sheltered bed outdoors[78, 200].
Division of suckers in
the dormant season. They can be planted out direct into their permanent
positions.
They do root from cuttings, though not as easily as other currants. Dividing a bushis easier.
