Alpine
Alpine: 55 days to harvest, 7-10 days to germinate, 4-6 inches between plants, hardy in zones 2-11. Fruit runs to about 5-8". Give it full sun and regular, consistent moisture; 1-1.5 inches per week water. Because this is a hybrid, seed saved from it will not repeat the parent — plan on fresh seed each year.
