Plant identity, types & settings
One plant guide. Clear details underneath.
Borage is the plant identity. Container, landscape, cutting, indoor, hydroponic, and harvest labels describe ways to grow it; they are not additional plant or cultivar names.
Ways to grow it
These are garden or production settings—not cultivar names and not extra plants.
Garden Crop
Keep harvest access open and label the species and intended plant part; culinary, aromatic, and dye uses are not interchangeable.
- Mature size
- 38 × 23 in
- Spacing
- 23 in
- Container
- 10+ gal · 15+ in deep
Indoor Hydroponic Crop
Select compact seed stock, provide active light, and sanitize the recirculating system between crops.
- Mature size
- 29 × 17 in
- Spacing
- 12 in
- Container
- 5+ gal · 15+ in deep
01 · Light & site
Give it the light its growth depends on.
Full sun, with roughly 6 to 8 hours of useful light. Warm soil and frost-free conditions
02 · Water & soil
Keep roots supplied without trapping water.
Water the complete root zone, then recheck conditions before watering again.
- Soil
- Loose, moderately fertile garden soil
- Drainage
- Well drained
- pH
- Species-dependent, commonly mildly acidic to neutral
03 · Spacing & roots
Make room for the mature plant.
Space plants about 18 inches apart. Expect a mature plant around 30 inches tall by 24 inches wide.
A branching root system needs the stated depth plus aerated soil around the mature spread.
04 · Start
Begin with the method that protects establishment.
Direct sow or transplant according to crop-specific temperature and root-disturbance guidance.
05 · Care
Support healthy growth through the season.
Usually self-supporting at the stated mature size. Add a discreet stake only if wind, bloom weight, or an exposed site makes it necessary.
- Upkeep
- Low
- Feeding
- Low
- Watch for
- Aphids, Powdery mildew, Self-seeding
06 · Flower or harvest
Flowering and wildlife value
50 to 80 days. Harvest only correctly identified plant parts with an established culinary use. Let some stems flower when pollinator value is part of the goal.
07 · Safety
Know the cautions before you place or use it.
- Food and medicinal use requires appropriate species and safety guidance.
- Coarse hairs can irritate sensitive skin.
