Care at a glance

Light

Bougainvillea 'Raspberry Ice' needs sun on the leaves, not just bright ambient room light. Full sun, at least 6 hours, for strong bract colour and the best leaf variegation; in shade it greens up, stretches, and flowers poorly. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water bougainvillea 'raspberry ice' when the top 5 cm of soil is dry, roughly every 5-10 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Allow to dry between waterings to encourage bracts; the variegated, less vigorous habit means it can scorch if bone-dry in heat, so water containers a touch more attentively than green types. Cut back in winter.

Soil and pot

Bougainvillea 'Raspberry Ice' grows best in free-draining, low-fertility loam or potting mix. Sharp-draining, slightly acidic soil (pH 5.5-6.5); add grit or perlite in pots. Avoid heavy, water-retentive mixes that rot the roots and suppress flowering. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Bougainvillea 'Raspberry Ice' sits happiest at around 30-50% humidity and 18-30°C (65-86°F). Prefers warm, dry to moderate air; high humidity with poor airflow promotes leaf spot. No misting needed. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed bougainvillea 'raspberry ice' sparingly. Feed every 3-4 weeks in the growing season with a high-potassium, low-nitrogen bloom fertiliser; too much nitrogen favours leaves over bracts. Withhold feed in winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on bougainvillea 'raspberry ice' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Loss of variegationInsufficient light causes leaves to revert toward solid green; move to full sun and remove any fully green reverted shoots.
  • Few bractsOverwatering or high-nitrogen feed; let it dry between waterings and use a bloom-boosting low-nitrogen fertiliser.
  • Leaf scorch on variegated marginsThe pale leaf edges burn if the plant dries out severely in intense heat; keep pots from going bone-dry during heatwaves.
  • Frost damageTender to cold; protect or bring indoors below about 2°C and prune blackened growth in spring.

Propagation

Semi-ripe stem cuttings in summer with rooting hormone and bottom heat; propagated only vegetatively so the variegation and raspberry bract colour stay true. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Bougainvillea 'Raspberry Ice' is pet-safe. Bougainvillea is not listed by the ASPCA as toxic to cats or dogs and is treated as non-toxic. The hazards are physical rather than chemical: thorns can injure mouths and paws, and the sap is a mild irritant that may cause drooling or mild stomach upset if chewed in quantity. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Bougainvillea 'Raspberry Ice' care — frequently asked questions

What is the common name for Bougainvillea 'Raspberry Ice'?

Bougainvillea 'Raspberry Ice' is most commonly called Bougainvillea 'Raspberry Ice', but it is also known as Variegated Bougainvillea. The names refer to the same species, so care instructions for Bougainvillea 'Raspberry Ice' apply identically to anything sold as Variegated Bougainvillea.

How much light does bougainvillea 'raspberry ice' need?

Bougainvillea 'Raspberry Ice' grows best in direct sun (at least 4-6 hours). Full sun, at least 6 hours, for strong bract colour and the best leaf variegation; in shade it greens up, stretches, and flowers poorly.

How often should I water bougainvillea 'raspberry ice'?

Water bougainvillea 'raspberry ice' when the top 5 cm of soil is dry, roughly every 5-10 days. Allow to dry between waterings to encourage bracts; the variegated, less vigorous habit means it can scorch if bone-dry in heat, so water containers a touch more attentively than green types. Cut back in winter. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is bougainvillea 'raspberry ice' toxic to cats and dogs?

Bougainvillea 'Raspberry Ice' is pet-safe. Bougainvillea is not listed by the ASPCA as toxic to cats or dogs and is treated as non-toxic. The hazards are physical rather than chemical: thorns can injure mouths and paws, and the sap is a mild irritant that may cause drooling or mild stomach upset if chewed in quantity.

What USDA hardiness zone does bougainvillea 'raspberry ice' grow in?

Bougainvillea 'Raspberry Ice' is rated for USDA zone 9-11 (frost-tender; container culture and overwintering indoors elsewhere) and RHS hardiness H1c. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
