Almost anything can grow in a Hugelkultur bed, except trees. Plants that spread vs. growing tall will also do better. For the first year, plant clovers, beans, and peas to fix the nitrogen and allow for the hugelbeds to decompose. In the second year and beyond, any nutrient-hungry plant will thrive such as Hugelkultur tomatoes, celery, potato, sweetcorn, pumpkins, zucchinis, and cabbage. Companion planting is also recommended.
