About Evergreen Amaryllis
Hippeastrum striatum · also called Striped-leaf Amaryllis, Brazilian Amaryllis · flowering
Hippeastrum striatum is a Brazilian species notable for remaining evergreen in warm conditions rather than going dormant like most hippeastrums. Produces vivid orange-red flowers striped with deeper veins in spring. Well-suited to bright interiors where a dry rest period is difficult to enforce. Toxic to pets due to lycorine alkaloids in the bulb and plant.
Ideal humidity: 45–65%
Watch for — Overwatering and root rot: The most common problem for an evergreen specimen kept in low-light indoor conditions in winter. Reduce watering frequency and improve light.
The watering schedule, season by season
Evergreen Amaryllis 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 evergreen amaryllis is year-round watering every 7–14 days; slightly reduced in winter but never fully withheld, 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 every 7–14 days.
- 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.
Unlike dormancy-requiring hippeastrums, H. striatum can be kept in light growth year-round in warm bright conditions. Water when the top 3–4 cm of compost is dry. Reduce frequency in winter if temperatures are cooler, but never let the compost dry out completely.

How to tell evergreen amaryllis needs water
A calendar is the worst way to water evergreen amaryllis. 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 evergreen amaryllis for a day is almost always safer than over-watering it.
Overwatering vs underwatering evergreen amaryllis
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For evergreen amaryllis 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 evergreen amaryllis drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for evergreen amaryllis 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 evergreen amaryllis, 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 evergreen amaryllis.
