Glossary of Plant Terms
Annual | A plant that completes its entire life cycle (germination, flowering, seed production, and death) in one growing season.
Biennial | A plant that grows leaves the first year and flowers and sets seed the second year, then dies.
Bulb | An underground storage structure (like tulips or daffodils) that contains all the nutrients needed to grow a new plant.
Cold Hardy | A plant that can tolerate cold temperatures and light frost without damage.
Container Plant | A plant grown in a pot or decorative container instead of directly in the ground.
Deadheading | Removing spent or faded flowers to encourage more blooms and keep plants looking tidy.
Deciduous | A plant or tree that loses its leaves each fall and grows new ones in spring.
Drought Tolerant | A plant that can survive with minimal watering once established.
Evergreen | A plant that keeps its leaves year‑round instead of dropping them seasonally.
Exposure | The amount of sunlight a plant receives each day. Full Sun = 6+ hours of direct sunlight, Partial Sun / Partial Shade = 3–6 hours, Full Shade = less than 3 hours.
Fertilizer | Plant food that provides nutrients to promote healthy growth and flowering.
Foliage | The leaves of a plant, often valued for color, texture, or shape.
Frost Tolerant | Able to withstand light frost without serious damage.
Germination | The process by which a seed sprouts and begins to grow.
Groundcover | Low‑growing plants that spread to cover soil, helping suppress weeds and prevent erosion.
Hardiness Zone | A geographic area defined by average winter temperatures that helps determine which plants will survive in a given region (based on the USDA Hardiness Zone Map).
Heat Tolerant | Able to withstand high summer temperatures without stress or damage.
Hybrid | A plant created by cross‑breeding two different varieties to combine desirable traits such as color, size, or disease resistance.
Indoor Plant | A plant well‑suited for growing inside the home in indirect or filtered light.
Mulch | Material (such as bark, straw, or compost) placed on top of soil to retain moisture, regulate temperature, and reduce weeds.
Perennial | A plant that lives for more than two years and typically returns each spring after winter dormancy.
Pinching Back | Removing the tips of stems to encourage fuller, bushier growth.
Pruning | Cutting back branches or stems to shape the plant, remove dead growth, and encourage healthy new growth.
Root Ball | The mass of roots and soil removed from a pot or the ground when transplanting.
Shade Loving | Plants that prefer low‑light conditions and grow best with limited direct sunlight.
Soil pH | A measure of how acidic or alkaline the soil is, which affects how plants absorb nutrients.
Tender Plant | A plant that is sensitive to cold and must be protected from frost or grown indoors in winter.
Transplant | Moving a plant from one location or container to another.
Watering In | Thoroughly watering a newly planted plant to settle soil around the roots and remove air pockets.
Well‑Drained Soil | Soil that allows excess water to flow away easily, preventing root rot.
