About Variegated Greater Periwinkle
Vinca major 'Variegata' · also called Variegated Greater Periwinkle, Variegated Periwinkle · flowering
A trailing evergreen sub-shrub bearing eye-catching leaves edged in creamy-white, offset by violet-blue spring flowers. Widely grown in containers and hanging baskets for its bright variegation. Slightly less vigorous than the straight species, making it somewhat easier to manage. Hardy to USDA zone 7.
Growth habit: Trailing, loosely mounding evergreen sub-shrub; stems root at nodes on contact with soil
Watch for — Leaf scorch on variegated margins: Creamy-white leaf margins are lower in chlorophyll and more sensitive to drought, intense sun, and salt spray. Site in dappled shade in hot climates, maintain consistent moisture, and avoid foliar fertiliser in strong sun.
What fertiliser variegated greater periwinkle actually wants — and why
Variegated Greater Periwinkle is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for variegated greater periwinkle: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed variegated greater periwinkle, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For variegated greater periwinkle:
Feed with a balanced liquid fertiliser every 3–4 weeks from spring through early autumn. High-nitrogen feeds encourage green reversion in variegated shoots — use a balanced or slightly potassium-high formula to maintain colour and flower production. Remove any all-green reverted stems promptly. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when variegated greater periwinkle is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for variegated greater periwinkle
Half strength is the safe default for variegated greater periwinkle — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water variegated greater periwinkle first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the variegated greater periwinkle watering schedule.
Signs you are over-feeding variegated greater periwinkle
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for variegated greater periwinkle:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding variegated greater periwinkle
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full variegated greater periwinkle care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of variegated greater periwinkle with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for variegated greater periwinkle
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding variegated greater periwinkle look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding variegated greater periwinkle year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of variegated greater periwinkle?
Flush the pot of variegated greater periwinkle with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
