A Change to Our Seed Guarantee

Solanum brevicaule seeds

The major portion of our business is selling clonal crops, in the form of roots and tubers.  Because roots and tubers are perishable and vulnerable to all kinds of problems in packing and shipping, we guarantee them.  You should expect that roots and tubers that you receive will substantially sprout and grow.  After that, it […]
