About Little Bunny Fountain Grass
Pennisetum alopecuroides 'Little Bunny' · also called little bunny fountain grass, miniature fountain grass · flowering
'Little Bunny' is the dwarf of the fountain grass family, a tidy 30-45 cm clump of arching green blades topped in late summer with fuzzy, buff-pink foxtail plumes. It thrives in full sun and average soil, turns golden-amber in autumn, and is grown widely in rock gardens, edging, and containers across US and UK borders.
Ideal humidity: Ambient outdoor humidity
The watering schedule, season by season
Little Bunny Fountain Grass flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for little bunny fountain grass is weekly while establishing in the first season, then only during prolonged drought, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
- Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
- Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.
Keep evenly moist the first year. Once rooted it is markedly drought-tolerant; water deeply but infrequently and avoid soggy soil, which rots the crown.

How to tell little bunny fountain grass needs water
A calendar is the worst way to water little bunny fountain grass. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch.
- Leaves or flower stems lose turgor and start to droop.
- Buds stall or the pot feels light.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering little bunny fountain grass for a day is almost always safer than over-watering it.
Overwatering vs underwatering little bunny fountain grass
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For little bunny fountain grass specifically:
Signs you are overwatering
- Yellowing leaves, bud drop, and a heavy, constantly wet pot.
- Mushy stems or crown rot at soil level.
- Fungus gnats and a sour soil smell.
Signs you are underwatering
- Wilting, bud and flower drop, and crispy leaf edges.
- A faded, stressed look and a rootball that has pulled from the pot sides.
Erratic watering — bone dry then flooded — makes little bunny fountain grass drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for little bunny fountain grass unless your water is very hard; rainwater is a safe default if leaf tips brown.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For little bunny fountain grass, the levers that matter most are:
- A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
- Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
- Empty the saucer after every water so the roots are never sitting in run-off.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of little bunny fountain grass.
