Yucca
Yucca filamentosa
Yucca filamentosa is pollinated exclusively by the yucca moth (Tegeticula yuccasella) — the moth lays eggs in yucca flowers AND deliberately pollinates them, ensuring her larvae have a food supply. It's one of the strictest mutualisms in nature.
How to care for yucca
Plant where you DON'T need to brush past it — leaves end in needle-sharp spines that have caused eye injuries. Cut the spent flower stalk after bloom. Aggressive root suckers; plant in a contained spot.
Garden uses & design ideas
Best garden use
Use it as structure near paths, fences, or foundation beds, leaving enough mature width so pruning stays light and natural.
Pair it with
Russian sage, Lavender, Sedum make easy companion choices because they share similar light, water, or visual texture needs.
Layout tip
Match it with full sun exposure, group it with other low-water plants so one irrigation zone can stay lean, and check USDA zones 4-10 before planting. Use the garden planner to test spacing around its mature size: 2-4 ft tall (foliage); 4-8 ft flower spike.
Gardener note — Double-check local invasive, edible, and toxicity guidance with your county extension office before planting around pets, children, or natural areas.
Companion plants
Yucca grows well alongside these — similar light, water, and texture needs.

What USDA zones does Yucca grow in?+
Yucca is hardy in USDA zones 4-10. Outside these zones, it can usually be grown indoors or as a seasonal annual.
How much sun does Yucca need?+
Yucca prefers full sun. Place it where it gets that light most of the day for best growth and flowering.
How often should I water Yucca?+
Yucca has low water needs. Allow the soil to dry between waterings. Plant where you DON'T need to brush past it — leaves end in needle-sharp spines that have caused eye injuries. Cut the spent flower stalk after bloom. Aggressive root suckers; plant in a contained spot.
How big does Yucca get?+
Yucca reaches a mature size of 2-4 ft tall (foliage); 4-8 ft flower spike. Growth rate is slow, so plan spacing accordingly when planting.
What plants grow well with Yucca?+
Yucca pairs well with Russian sage, Lavender, Sedum, Agave. These companions share similar care requirements and don't compete aggressively for resources.
What pests affect Yucca?+
Common Yucca problems include essentially pest-free; deer-resistant. Catching early signs in routine inspection prevents most damage.
When does Yucca bloom?+
Yucca blooms in early to mid summer in creamy white (massive panicle). Deadheading spent flowers (where applicable) often encourages a longer bloom window.
