Fascicularia bicolor var. pitcairniifolia – Hardy Terrestrial Bromeliad, Scarlet, Blue and Gold Autumn Display
Fascicularia bicolor var. pitcairniifolia — known in Chile as puñeñe and in Britain as the baboon's bottom — is one of the most spectacular and hardy terrestrial bromeliads that can be grown in temperate gardens. Out of flower, its broad glaucous-green toothed rosettes with silvery undersides form a graphic, architectural clump. At autumn flowering, the transformation is breathtaking: the inner leaves turn vivid scarlet red, revealing at the centre a head of electric blue flowers with golden-yellow stamens — a complete tricolour display, botanical and spontaneous, of astonishing beauty. The var. pitcairniifolia is distinguished by its broader leaves and more compact habit. Hardy to -10°C in well-drained soil. Find it among our rare botanical curiosities.
What is Fascicularia bicolor var. pitcairniifolia?
Fascicularia bicolor var. pitcairniifolia (syn. Fascicularia pitcairniifolia, Hechtia pitcairniifolia, Fascicularia bicolor ssp. bicolor) is a terrestrial and saxicolous bromeliad belonging to the family Bromeliaceae — the same as the pineapple (Ananas comosus). It is the only species in the genus Fascicularia, endemic to Chile, where it grows naturally on rocky coastal cliffs and slopes in the central zone, in areas of Mediterranean climate. In Chile it is known as puñeñe.
The var. pitcairniifolia differs from the type bicolor form in having broader leaves and a more compact, dense habit — characters clearly visible in our nursery photographs. It is primarily terrestrial and saxicolous (on rocks), whereas the subspecies canaliculata is epiphytic in the temperate Valdivian forests of southern Chile. The name Fascicularia derives from the Latin fasciculus (bundle) — referring to the densely bundled leaves — and bicolor celebrates the spectacular red and green bicoloration of the foliage at flowering time.
This bromeliad has naturalised in several mild-winter regions of Western Europe: the Cornish coast, Isles of Scilly, Guernsey, western Ireland — demonstrating its remarkable capacity to thrive outside its native range. In France, it is found in the most favoured Breton and Mediterranean gardens.
What are the unique characteristics of Fascicularia bicolor var. pitcairniifolia?
- Spontaneous botanical tricolour at flowering — red, blue and gold: this is the most extraordinary phenomenon of this plant. At autumn flowering, the central leaves of each rosette change from green to vivid scarlet red — a visual signal to pollinators indicating the presence of nectar. Exactly as female baboons' hindquarters turn red when receptive — hence the vivid British nickname. At the centre of this red star, a compact head of electric blue to blue-violet tubular flowers with golden-yellow stamens and anthers creates a complete primary tricolour of stunning chromatic precision.
- Broader glaucous-green foliage than the type form: the var. pitcairniifolia has wider and more compact strap-like leaves than the classic bicolor — glaucous to olive-green, with a characteristic silvery underside. The leaves are leathery, linear, with a sharp pointed tip and toothed-spiny margins, reaching over 60 cm in length.
- Spreading rosette habit, dense and graphic: the plant forms stemless rosettes that multiply by producing peripheral offsets, progressively creating an imposing clump reaching 60 to 80 cm in height for 1 to 2 m in spread at maturity. Each individual rosette resembles a flattened plate — an architecturally very graphic vegetative structure.
- The rosette flowers then dies — but the clump survives: after flowering, the central rosette dries — as with all bromeliads — but the clump is already stocked with numerous offsets that perpetuate and enlarge the plant indefinitely. The scaly fruits that persist after flowering are also very decorative.
- Hardy to -10°C in perfectly free-draining soil: this is the hardiest terrestrial bromeliad available in European horticulture. Well established in a very free-draining soil in full sun, it tolerates intense but brief frosts — making it accessible in many French regions with moderate winters.
- Slow growth — a plant that lasts decades: growth is slow (several years to form a fine clump), but the plant lives extremely long — decades — progressively widening by production of new offsets.
How to grow Fascicularia bicolor var. pitcairniifolia?
- Light: full sun is essential. Flowering is directly linked to the amount of sun received — in insufficient light, the plant grows but rarely flowers, and the red bract colouration is less intense. In very hot regions, light afternoon shade is tolerated.
- Soil: absolutely free-draining, mineral, neutral to acid. It grows on rocks in the wild — it manages in poor, stony and rocky soils. The absolute enemy is waterlogging at the crown, particularly in winter. In heavy, wet soil, it will inevitably rot. In containers, compose a mix of ericaceous compost, free-draining compost and add a good layer of volcanic rock at the base.
- Watering: regular in the first year to support establishment. Once well rooted, it is very drought-tolerant. In summer, never let the soil dry out completely. In winter, let nature take its course — rainfall is sufficient in wet-winter regions. Preferably use non-calcareous water.
- Frost hardiness: remarkable for a bromeliad — to -10°C for short periods in very free-draining soil and once well established. Frost combined with soil moisture is far more dangerous than frost alone. Protect young plants for the first 2-3 winters and choose a position sheltered from cold wind.
- Planting: in spring, in a good sunny position. Soak the rootball for a few minutes before planting. Prepare a bed of loose soil, compost and draining material. Water regularly in the first year.
- Feeding: a spring application of appropriate fertiliser can stimulate growth and flowering, particularly in containers.
What are the care requirements?
- Virtually no maintenance: one of the most autonomous plants available. No pruning, no regular watering once established, no treatment.
- Removing spent rosettes: after flowering, the central rosette progressively dries. You can leave it in place (it protects the offsets) or remove it cleanly once fully dried.
- Regular thinning: for abundant flowering, the plant needs space. Divide dense clumps regularly — this is also the best propagation method.
- No susceptibility to diseases or pests: Fascicularia is virtually free of all phytosanitary problems — its spiny leaves even deter browsing animals.
Where to plant Fascicularia bicolor var. pitcairniifolia?
- In a rock garden or dry stone wall: its natural habitat. Planted between rocks, it thrives and forms spectacular colonies over time.
- In an exotic full-sun border: combined with yuccas, agaves, puyas, phormiums or cordylines, it composes exotic, graphic scenes of great botanical coherence.
- In a coastal garden: its resistance to sea spray and wind makes it an ideal plant for the coastal gardens of Brittany, Vendée, Charente and the Mediterranean.
- In a large pot or trough: in cool regions, grown in a large well-drained container, it can be sheltered during periods of hard frost, then brought out again from spring. Find our other exotic botanical curiosities to compose your collection gardens.
What are the advantages for collectors?
- The only hardy terrestrial bromeliad: in a horticultural world where bromeliads remain confined to the indoors, Fascicularia is a fascinating botanical anomaly — a bromeliad you can plant in the garden like an ordinary perennial.
- A spontaneous botanical tricolour display: no plant grown in European gardens spontaneously produces a red/blue/gold tricolour of such intensity and chromatic precision — a natural phenomenon of beauty that appears almost artificial.
- The var. pitcairniifolia: more compact and easier: its more gathered habit than the type form makes it easier to integrate into collection compositions and more accessible to small and medium gardens.
- A monotypic genus — a botanical rarity: growing Fascicularia bicolor means growing the sole representative of an entire botanical genus — a collector's privilege and responsibility.
- Naturalised in Western Europe: the spontaneous presence of this plant in Cornwall and the Isles of Scilly is an invitation to grow it in the mild oceanic-climate regions of France.
How to propagate Fascicularia bicolor var. pitcairniifolia?
Propagation is mainly by separation of offsets:
- The clump regularly produces offsets at its periphery, equipped with their own roots.
- In spring, carefully lift well-rooted offsets (as shown in our nursery photograph), retaining as many roots as possible.
- Replant immediately in a free-draining substrate and water regularly until establishment.
- Seed propagation is possible but slow — several years before obtaining a flowering plant.
