Queen’s tears
Billbergia nutans
In other languages: Billbergia (Nederlands) · Billbergia (Français)
Billbergia nutans is a bromeliad from South America, from southern Brazil to Paraguay, Uruguay and northern Argentina. It forms dense clumps of narrow, grass-like, grey-green leaves with finely toothed edges. In late winter and spring, arching flower spikes appear with bright pink bracts and flowers in green, violet-blue and yellow. Its common name, queen’s tears, refers to the drops of nectar that can fall from the flowers. It is one of the easiest bromeliads: it tolerates cool conditions, grows quickly and lives on after flowering through its many offsets.

Identify
Queen’s tears: how do you recognise it?
- Habit
- Dense clump of narrow, upright to arching rosettes, 30–40 cm tall and up to 50 cm wide.
- Leaves
- Narrow and strap-like, 30–40 cm long, grey-green, with tiny teeth along the edge; sometimes reddish in good light.
- Flower
- Nodding spikes with bright pink bracts; the tubular flowers are green edged with violet-blue, with yellow stamens.
- Flowering time
- From January to April; each rosette flowers once.
- Roots
- Small and mainly for anchorage; a small pot is enough.
Flowering: January–April · Plants: April–May · Pruning: April–May
In your garden
Why grow it?
- Exotic, nodding flowers in late winter and spring, when little else flowers indoors.
- Very tough and tolerant: it copes with cool rooms and a little neglect.
- Quickly fills a pot with many rosettes, which flower again every year.
- The flower spikes also look lovely in a small vase.
- Easy to divide and share with friends.
Queen’s tears: where does it grow best?
- Bright light to light shade: an east or west window is ideal. Morning sun is fine, strong midday sun is not.
- Normal room temperature, but it also tolerates cool conditions down to 5 °C; a slightly cooler winter spot at 10–15 °C suits it well.
- Open, humus-rich compost: potting compost mixed with some fine bark, or bromeliad compost.
- In summer it can go outside in a sheltered spot in light shade.
- Light
- Bright, out of direct sun
- Potting soil
- Multi-purpose compost or airy, humus-rich compost
- Acidity
- Acid or neutral
- Watering
- Moderately
- Size
- 0.4 m tall, 0.5 m wide
- Temperature
- Minimum 5 °C
Goes well with
- Spider plant: Just as tough and tolerant, with similar narrow leaves.
- Clivia: Also likes a cool winter and flowers in spring.
- Air plant: A related bromeliad that you can simply lay down or hang up.
- Cast-iron plant: Large, dark leaves that also tolerate a cool spot.
Maintenance
Queen’s tears: when and how to plant it?
Plant in April–May.
- Repot or divide in April or May, after flowering.
- Choose a wide, fairly shallow pot with a drainage hole; it has few roots.
- Use an open mix of potting compost and fine bark, or bromeliad compost.
- Set the rosettes at the same depth as before and firm them in well; support them temporarily with a small cane if needed.
- Water in moderately, preferably with rainwater, then let the compost dry slightly.
Care
- Water
- From spring to autumn keep the compost lightly moist, preferably with rainwater; let the surface dry between waterings. Water more sparingly in winter.
- Feeding
- From April to September, liquid feed at half strength or bromeliad feed every three to four weeks.
- Spent rosettes
- A rosette that has flowered slowly dies back. Cut it off at the base as soon as it yellows, so the young offsets get room.
- Repotting
- Only when the pot is overcrowded, every two or three years: it flowers well when pot-bound.
- Humidity
- Ordinary room air is fine; it is far less demanding than other bromeliads.
Tip: Let it fill its pot: a dense clump flowers most freely. Only divide it in spring after flowering, when the pot is really overcrowded.
Queen’s tears: when to prune it?
Pruning months: April–May.
When: After flowering, in April–May, remove spent flower spikes and rosettes.
How:
- Cut withered flower spikes off at their base.
- Cut rosettes that have flowered and are turning yellow off at the base.
- Leave the young offsets: they will flower in a year or two.
Propagation
- Division
- After flowering, in April–May, divide a full clump into pieces of three to five rosettes and pot each piece separately.
- Offsets
- Cut off an offset at least a third the size of the parent with a sharp knife and plant it in open compost.
Queen’s tears: how does it get through the winter?
- House plant: it cannot take frost, but tolerates cool conditions down to about 5 °C.
- A bright, slightly cooler spot at 10–15 °C is ideal; there it flowers in late winter.
- Water sparingly in winter and do not feed.
- A bright, frost-free conservatory or porch also suits it.
Diseases and pests
- Scale insects: Brown bumps under the leaves. Wipe off with a cloth or cotton bud dipped in methylated spirit.
- Mealybug: White fluffy tufts between the leaf bases. Remove with a cotton bud dipped in methylated spirit.
- Rot: Brown, soft leaf bases caused by overly wet compost. Water less, remove rotten parts and replant in open compost.
- No flowers: A clump that is too young, a spot that is too dark or a winter that is too warm. Give it more light and a cooler winter, and do not divide it too often.
Through the year
- January: Start of flowering. Bright, cool spot.
- February: Flowering. Water sparingly.
- March: Flowering. Cut a spike for a small vase if you like.
- April: End of flowering. Remove spent rosettes, divide or repot. Start feeding again.
- May: Divide or repot. In late May possibly outside in light shade.
- June: Water, preferably with rainwater. Feed every three to four weeks.
- July: Water and feed. Keep out of strong midday sun.
- August: Water and feed.
- September: Bring it back in before cold nights. Last feed.
- October: Water less. Stop feeding.
- November: Keep it cool and bright, around 10–15 °C.
- December: Water sparingly. Leave it bright and cool.
