About Tenby Daffodil
Narcissus obvallaris · also called Tenby Daffodil, St David's Daffodil · flowering
The Tenby Daffodil is a compact, early-blooming wild daffodil naturalised in Pembrokeshire, Wales, bearing solitary rich-golden flowers with a wide trumpet on slender stems in early spring. It is one of the UK's rarest native flowers. All Narcissus parts are toxic to pets and people; contains lycorine and alkaloids.
Ideal humidity: 50-70%
Watch for — Narcissus basal rot (Fusarium): Fungal rot enters through the basal plate, causing yellowing and collapse. Remove infected bulbs immediately and improve drainage.
The watering schedule, season by season
Tenby Daffodil 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 tenby daffodil is when the top 3-5 cm of soil is dry during active growth, roughly every 7-10 days, 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 7-10 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.
Needs consistent moisture during leaf and flower production in late winter and spring, then can tolerate summer drought once dormant. Never let bulbs sit in waterlogged soil.

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

How often should I water tenby daffodil?
Water tenby daffodil when the top 3-5 cm of soil is dry during active growth, roughly every 7-10 days.

What are the signs of an underwatered tenby daffodil?
Wilting, bud and flower drop, and crispy leaf edges. A faded, stressed look and a rootball that has pulled from the pot sides.
