I got about 15 varieties on my first year. I lost about 9 the first winter, from not really doing things the right way and not knowing how to care for those babies... Fortunetly, I have learned from my mistakes. Still, after 5 years, want to get new varieties to experiment and taste. I find the entire process awesome, from rooting to harvesting!
PS:Good list, RDB is by far my most vigorous grower, and producer. Aside from the great taste. I am planting a few outside this year and hoping these survive the next winter. Of course, all my other ones sleep the winter cozy in the garage.
Good luck! happy growing!
