Hippeastrum 'Red Lion' (Amaryllis Red Lion)
Hippeastrum 'Red Lion' (Amaryllis Red Lion)
Introduction
Hippeastrum 'Red Lion' (Amaryllis 'Red Lion', family Amaryllidaceae) is native to South America (hybrid), grown for enormous (15–20 cm) trumpet-shaped deep red flowers, 2–4 per stem, on tall (50–75 cm) sturdy scapes. The classic indoor Amaryllis for winter flowering — produces enormous, spectacular red trumpet flowers in midwinter.
Flowers: enormous (15–20 cm) trumpet-shaped deep red flowers, 2–4 per stem, on tall (50–75 cm) sturdy scapes. Foliage: strap-shaped, 40–60 cm, arching, bright green. Growth habit and indoor size depend on species. Most flowering houseplants require good indirect light for reliable blooming and specific care during dormancy or resting periods between bloom cycles.

History & Cultural Significance
Flowering houseplants represent the desire to maintain natural bloom cycles indoors — recreating the seasonal color of outdoor gardens within the home. They have been central to home decoration since the Victorian parlor plant tradition.
About Flowering Houseplants
Flowering houseplants challenge the common perception that indoor plants are exclusively about foliage. Saintpaulia (African violet, Gesneriaceae) was discovered in 1892 by Baron Walter von Saint Paul-Illaire in the cloud forests of the Usambara Mountains, Tanzania — within decades it became the most popular flowering houseplant worldwide, with over 16,000 registered cultivars. Anthurium (Araceae) produces a modified leaf (spathe) surrounding a spadix covered in tiny true flowers — the glossy red 'petal' is actually a bract. Spathiphyllum (peace lily) uses a similar bract structure. Cyclamen persicum, native to Mediterranean scrublands, blooms in winter when grown cool (12–16°C).

Family Amaryllidaceae. Native to South America (hybrid). Flowering houseplants typically evolved in seasonally variable climates with distinct wet/dry or warm/cool cycles that trigger bloom. Replicating these triggers indoors often requires a period of reduced water and/or cooler temperatures.
Growth Timeline
Flowering cycles vary: some bloom continuously (African violet), others seasonally (Cyclamen, Clivia). Establish dormancy/rest routines for reliable annual flowering.
Light Requirements
Requires medium to bright indirect light for reliable flowering. Most flowering houseplants need significantly more light than foliage-only plants. Place within 1–1.5 m of a south or east window. Grow lights (12–14 hours) maintain flowering year-round.
Group Light Guide
African violets, Anthurium, and other flowering indoor plants need bright indirect light to bloom reliably. 10–12 hours of bright light daily encourages continuous flowering. LED grow lights work very well. North windows are usually insufficient for flowering.
Watering
Varies by species. Most flowering houseplants need a dry rest period to trigger bloom. During flowering: keep evenly moist. During dormancy: reduce to minimal watering. Use tepid water. Fluoride sensitivity varies.
Group Watering Guide
Consistent watering is key for flowering plants. African violets prefer bottom watering to avoid crown rot. Anthurium needs moist but not wet soil. Most flowering houseplants benefit from slightly reduced watering after blooming to encourage the next flower cycle.
Humidity & Temperature
Most prefer 50–65% humidity. Temperature requirements vary — check individual species. Most benefit from a cooler resting period (15°C for 6–8 weeks) before the main flowering season.
Group Humidity & Temperature Guide
African violets perform best at 50–60% RH with constant temperatures of 18–24°C; cold water drops on leaves cause ring spot (white marks). Anthurium needs higher humidity (60–80%) to maintain glossy, healthy foliage. Most flowering houseplants require stable temperatures — fluctuations greater than 8°C between day and night inhibit bud development and cause bud blast. Avoid cold windowsills at night where temperatures can drop below 12°C. Heated propagation mats help maintain constant root zone temperature for consistent blooming.

Native origin: South America
Soil & Potting
Well-draining mix appropriate to each species. Most prefer slightly pot-bound conditions for best flowering. Repot after flowering or in spring.
Group Soil Recipes
Flowering plants need nutrient-rich, well-draining mix: 50% potting soil, 25% perlite, 15% coco coir, 10% compost. African violets require a special violet mix or very light, airy soil. Anthuriums prefer orchid-type mix. pH 5.5–6.5. Fresh soil annually supports blooming.
| Repotting frequency | every 2–3 years (spring) |
| Pot size up | 2–3 cm larger diameter than current |
| Growth rate | moderate |
| Drainage | Essential — always use pots with drainage holes |
Fertilizing
High-phosphorus bloom fertilizer (5-10-5 or similar) during the bud development phase. Balanced fertilizer during active growth. No fertilizer during dormancy.
Group Fertilizing Guide
Flowering houseplants need phosphorus-rich fertilizer (15-30-15 or African violet formula) for sustained blooming. Feed African violets every 2 weeks with specialized violet fertilizer — wick-watered plants benefit from constant dilute feed (quarter strength in every watering). Anthurium prefer balanced feed (20-20-20) every 2 weeks. Never fertilize newly repotted plants for 4–6 weeks.
| Spring (Mar–May) | Resume feeding every 2–3 weeks with balanced liquid fertilizer at half strength |
| Summer (Jun–Aug) | Peak feeding period — every 2–3 weeks at full dilution rate |
| Autumn (Sep–Nov) | Reduce to monthly, then stop by late October |
| Winter (Dec–Feb) | No fertilizer — plant is in rest phase, roots cannot absorb nutrients efficiently |
Propagation
Varies by species: division (African violets, Clivia), tuber/bulb division (Cyclamen, Kalanchoe), stem cuttings (Columnea, Aeschynanthus), offsets (Hippeastrum).
Group Propagation Guide
African violets propagate from leaf cuttings: cut a healthy middle leaf with 3 cm petiole, insert petiole at 45° into moist perlite or vermiculite, and plantlets emerge in 6–10 weeks. Anthurium propagates by division of crowded clumps in spring — each division needs at least 2 leaves and healthy roots. Spathiphyllum divides easily when root-bound. Cyclamen propagate from seed (slow, 12–18 months to bloom) or rarely from tuber division. Most flowering houseplants root more successfully with bottom heat (22–25°C) and a clear plastic humidity dome.
| Method | Technique | Best timing | Success rate |
|---|---|---|---|
| bulb division | Follow standard technique for this method. | Spring | — |
| Offsets / Pups | Wait until offsets are 1/3 the size of the mother plant. Separate with a clean cut ensuring roots are attached. Pot independently. | Spring–Summer | Very high (90%+) |
| seeds | Follow standard technique for this method. | Spring | — |
Pruning & Maintenance
Remove spent flowers promptly to encourage continued flowering. Trim dead foliage. Pinch back for bushy habit in trailing/vining forms.
Group Pruning Guide
Deadhead spent blooms promptly to encourage continuous flowering — pinch or cut faded flowers at the base of the flower stalk. For African violets, remove entire flower stalks once all blooms fade; remove any leaves growing into the centre of the rosette to maintain the symmetrical crown. Anthurium spathes can be removed when they turn green. Prune leggy spathiphyllum foliage at the base. Never use leaf shine products on African violets as the hairy leaves trap the product, causing cell damage.
| Pruning frequency | as needed during the growing season |
| Best time to prune | Early spring before new growth flush |
| Leaf cleaning | Monthly — wipe with damp cloth to clear stomata |
| Tool sterilization | 70% isopropyl alcohol between cuts |
| Growth rate | moderate |
Common Problems
No flowering: insufficient light or wrong dormancy conditions. Yellow leaves: overwatering. Bud drop: temperature fluctuations or low humidity. Fungal issues: poor airflow.
Troubleshooting Guide
No flowers: review light, dormancy period, and fertilizer (check phosphorus). Bud drop: temperature or humidity fluctuation. Yellow leaves: overwatering.
Pest & Disease Guide
Mealybugs, aphids, and spider mites are common. Regular inspection. Treat with insecticidal soap. Remove affected buds/flowers before treatment.
Group Pest Profile
African violets attract cyclamen mites (Steneotarsonemus pallidus) — microscopic pests causing distorted, hairy new growth in the crown. Treat with miticide; isolate affected plants immediately as cyclamen mites spread rapidly. Mealybugs hide in the dense leaf rosettes. Thrips damage flowers, causing brown streaks and shortened bloom life. Anthurium are susceptible to scale and mealybugs. Botrytis (grey mould) attacks spent flowers in humid, stagnant conditions — remove faded blooms promptly. Crown rot from overwatering is more damaging than any pest for African violets.
| Pest | Identification | Treatment |
|---|---|---|
| Spider mites | Fine webbing on leaf undersides, stippled yellowing leaves | Shower blast, neem oil spray, predatory mites (Phytoseiulus persimilis) |
| Mealybugs | White cottony masses in leaf axils and stem joints | Isopropyl alcohol on cotton swab, insecticidal soap, systemic imidacloprid |
| Scale insects | Brown or tan bumps on stems and leaf midribs | Manual removal, horticultural oil, systemic treatment for heavy infestation |
| Fungus gnats | Small black flies around soil, larvae in wet substrate | Allow soil to dry between waterings, BTi (mosquito dunks), yellow sticky traps |
| Thrips | Silver streaks on leaves, black frass dots | Blue sticky traps, spinosad spray, systemic treatment |
Pet & Child Safety

Display & Styling
Flowering plants provide seasonal color in living rooms, dining areas, and bedrooms. Position where the flowers can be appreciated and smelled. Use decorative cache pots to complement flower colors.
Group Display Ideas
Position flowering plants where their blooms can be fully appreciated. African violets make wonderful windowsill collections. Anthurium adds a tropical touch to modern interiors. Group blooming plants together to create a colorful focal point. Rotate regularly for even light exposure.
| Best position | floor specimen |
| Light zone | bright indirect |
| Humidity needs | low-medium (30-40%) |
| Indoor height | 50-75 cm |
Companion Planting Indoors
Flowering plants pair beautifully with complementary foliage plants that share similar care requirements. Grouping provides humidity and creates natural, garden-like displays.
Seasonal Care Calendar
Most flowering houseplants have distinct active growth, flowering, and rest periods. Understand each species' specific cycle to optimize flowering performance.
Group Seasonal Guide
Spring: Increase feeding with bloom-promoting fertilizer (higher phosphorus). African violets and anthuriums begin their main flowering cycle. Repot after bloom flush if needed. Summer: Maintain consistent watering — dry stress causes bud drop. Remove spent flowers promptly to encourage continued blooming. Autumn: Many flowering houseplants have a secondary bloom period. Reduce feeding but continue with bloom fertilizer if buds are forming. Winter: Supplemental lighting (grow lights, 12–14 hours daily) maintains blooming through short winter days. Cool night temperatures (15–18°C) benefit cyclamen and many other flowering species.
| Season | Watering | Feeding | Key tasks |
|---|---|---|---|
| Spring | Increase gradually | Resume every 2–3 weeks | Repot if needed, prune dead growth, check for overwintering pests |
| Summer | Most frequent | Peak feeding | Monitor for pests, rotate for even growth, increase humidity |
| Autumn | Reduce gradually | Taper off by October | Move away from cold windows, reduce watering frequency |
| Winter | Minimal | None | Maintain min. 13°C, increase light if possible, watch for dry air from heating |
