| Name | Scientific | Family | Form | Height | pH | Zones | Sun | Water | Difficulty | Conservation |
|---|---|---|---|---|---|---|---|---|---|---|
| Parsley, Garden Parsley, Petroselinum | Petroselinum crispum | Apiaceae | herb_non_graminoid | 12-24 inches | 6–7 | 4-9; grown as an annual in all zones | Full Sun, Partial Sun, Partial Shade | Keep soil consistently moist but not saturated. Provide about 1 inch of water per week and mulch to reduce bolting. | NE | |
| Parsnip, Garden Parsnip, Wild Parsnip (wild form) | Pastinaca sativa | Apiaceae | herb_non_graminoid | 2-4 feet (60-120 cm) | 6–7 | 2a-9b | Full Sun, Partial Sun | Ensure deep, even watering during summer root expansion to prevent root splitting and woody cores. | LC | |
| Pickerelweed, Blue Pickerel, Heartleaf Pickerelweed | Pontederia cordata | Pontederiaceae | herb_non_graminoid | 2-4 feet (60-120 cm) | 5.5–7 | 3a-10b | Full Sun, Partial Sun | Must be kept in continuously submerged or saturated substrates. Submerge crown under 2 to 12 inches (5-30 cm) of standing water. | LC | |
| Popcorn, Popping Corn | Zea mays | Poaceae | herb_graminoid | 5-8 feet (1.5-2.4 m) | 6–6.8 | 2a-11b | Full Sun | Provide 1-1.5 inches of water weekly; critical moisture periods occur during silking, tasseling, and kernel development. | LC | |
| Potato, Irish Potato, Spud, Papa, Cultivated Potato | Solanum tuberosum | Solanaceae | herb_non_graminoid | 1.5-2 feet | 4.8–6.5 | USDA 3-10 as annual; 8-10 may overwinter tubers or volunteers | Full Sun | Provide consistent moisture, about 1-2 inches per week, especially during tuber initiation and bulking. Avoid waterlogged soil to reduce tuber rot. | NE | |
| Indian Fig Prickly Pear, Nopal, Tuna Cactus, Barbary Fig | Opuntia ficus-indica | Cactaceae | succulent_stem | 10-15 feet (3-5 m) | 6–8.5 | 8b-11b | Full Sun | Irrigate lightly during early cladode emergence to maximize crop yield; otherwise entirely drought-tolerant. | DD | |
| Field Pumpkin, Sugar Pumpkin, Jack-o'-Lantern | Cucurbita pepo | Cucurbitaceae | climber | 1.5-2.5 feet (45-75 cm) | 6–6.8 | 3a-11b | Full Sun | Deep, regular irrigation of 1-2 inches per week applied directly at soil level to prevent foliar fungal diseases like powdery mildew. | LC | |
| Purple Coneflower, Eastern Purple Coneflower | Echinacea purpurea | Asteraceae | herb_non_graminoid | 2-4 feet (60-120 cm) | 6–7.5 | 3a-9b | Full Sun, Partial Sun | Low; drought-tolerant once established. Supplementary water during severe heat waves improves flowering duration. | LC | |
| Quinoa, Quinua, Andean Mother Grain | Chenopodium quinoa | Amaranthaceae | herb_non_graminoid | 3-7 feet (90-210 cm) | 6–8.5 | 4a-10b | Full Sun | Irrigate during germination and seedling establishment; reduce moisture drastically once flowering begins to prevent downy mildew. | NE | |
| Radicchio, Italian Chicory, Red Chicory of Chioggia | Cichorium intybus | Asteraceae | herb_non_graminoid | 8-12 inches (20-30 cm) | 6–7 | 4a-9b | Full Sun, Partial Sun | Provide 1 inch of water weekly. Ensure steady soil moisture during late summer head formation to avoid tipburn. | LC | |
| Radish, Garden Radish, Daikon, Oriental Radish | Raphanus sativus | Brassicaceae | herb_non_graminoid | 6-12 inches foliage; up to 36 inches when flowering | 6–7 | 2a-10b, cultivated as a cool-season crop | Full Sun, Partial Sun, Partial Shade | Provide consistent, even moisture. Drought stress causes pithy, cracked, or excessively pungent roots. | NE | |
| Red Raspberry | Rubus idaeus | Rosaceae | subshrub | 4-6 feet (1.2-1.8 m), occasionally up to 8 feet (2.4 m) | 5.5–6.5 | 3a-9b | Full Sun, Partial Sun, Partial Shade | Provide 1-1.5 inches of water per week during flowering and fruiting. Use drip irrigation where possible to keep foliage dry and reduce fungal disease. | LC |
