Epiphytes, focusing on air plants grown without soil
Growth & habit
Epiphytic describes a way of living, not a relationship: the host plant provides support.
Foliage
Tillandsia often has narrow green or silvery-scaled leaves. Other epiphytes have very different foliage.
Family
Several families; Tillandsia: Bromeliaceae
Origin
Epiphytes occur worldwide, especially in the tropics; Tillandsia is native to the Americas.
Height
Species-dependent: small rosettes to long hanging stems. The group has no single mature size.
Bloom
Depends on species and cultivation; Tillandsia usually develops colourful flower stems followed by offsets.
Toxicity
Identify the species before buying; this group includes very different plants. Not intended as food.

For Tillandsia, timing depends on species and maturity; flowering is not obligatory.
Guidance for Germany and Central Europe. Position, weather, species and cultivar shift these windows; indoor and container plants also depend on their winter conditions.
Your seasonal care plan
January
Check light and ventilation; avoid cold, wet rosettes.
February
Inspect mounts and plant bases.
March
Reassess water needs as days become brighter.
April
Care for growing air plants according to need and allow them to dry afterwards.
May
Protect from direct midday sun behind glass.
June
Check drying more often in warmth; drain centres after watering.
July
Maintain ventilation and avoid trapped heat.
August
Watch offsets and separate only robust ones carefully.
September
Bring any outdoor plants indoors before cold nights.
October
Match watering and feeding to light and growth.
November
Keep away from cold glass and hot radiator air.
December
Position displays so watering and drying remain practical.
Highlighted months are guidance, not fixed dates. Observe the plant, root ball and weather; water, feed and repot according to actual need.

Care tips
1Identify the species before choosing water and growing medium.
2Mount grey air plants with ventilation and let them dry after watering.
3Use the specific guides for epiphytic orchids and jungle cacti.
Fruit & seeds
Fruit and seed formation
After pollination, Tillandsia may produce capsules with fine hairy seeds. Other epiphytes have different fruit types.
Harvest and use
Ornamental plants, not a food crop. Use robust offsets for straightforward propagation.
Plant knowledge at a glance
Position, benefits & character
+
Position & soil
For the air plants described here: bright filtered light, warmth and good air movement. Green tank bromeliads need different watering from grey air plants.
Distinctive features
Silvery leaf scales absorb water. Aerial roots often provide attachment; they do not mean the plant can live on air alone.
Benefits
Mounted plants add leaf texture to bright walls and open displays. Plan access for watering and drying from the start.
Partners & symbioses
Epiphytes do not parasitise their supporting plant. Use suitable indoor mounts; constantly wet closed glass displays do not suit grey air plants.
Pruning & growth habit
+
Epiphytic describes a way of living, not a relationship: the host plant provides support.
1. Retain a healthy rosette
Do not cut into the green centre. Remove only dry, dead material carefully.
2. After flowering
The mother rosette may decline gradually as offsets grow. Remove parts only once fully dead.
Nursery forms
+
This overview explains nursery supply forms. It does not indicate current availability in the GREEN24 shop.
Young plant
Common form
Individual air plants or offsets; check a firm base and undamaged growing centre.
Container-grown
Ask a specialist nursery
Some green bromeliads are sold potted. This is not the standard way to grow grey air plants.
Bare-root
Ask a specialist nursery
Unpotted air plants can be mounted; do not plant them like bare-root garden perennials.
Propagation & grafting
+
Propagation
Tillandsia produces offsets after flowering. Separate robust offsets carefully once large enough, or retain them as a clump. Seed propagation is slow and needs warmth, light and ventilation.
Grafting
Mounting is not grafting. The mount and fastening should support the plant without crushing leaves or its growing centre.
Species & cultivars
+
Tillandsia caput-medusae
Curved leaves above a swollen base; take particular care with drainage after watering.
Tillandsia xerographica
Broad, silvery, recurved leaves form a striking rosette.
Tillandsia usneoides
Fine hanging stems, commonly called Spanish moss; botanically not a moss.
Pests & diseases
+
These signs support an initial assessment. Different causes may look alike; choose a treatment only after identifying the problem.
Soft plant base
Check for trapped water and inadequate ventilation. Drain grey air plants thoroughly after watering.
Strongly curled leaves
Check water needs and room temperature, allowing for the species’ natural leaf shape.
Pale dry patches
Check sun and heat exposure at the window; adjust the position gradually.
Hardiness · USDA
+
No single hardiness rating for all epiphytes
Keep the air plants described here frost-free and sheltered indoors in winter. Consider light, moisture and temperature together.
Tillandsia – tropische Zimmerkultur
No blanket USDA zone: the epiphytic way of living covers very different species. RHS recommends temperatures above about 12°C for the air plants covered here.
USDA zones describe long-term average winter extremes. Containers, young plants, wet soil, wind and late frost need separate consideration.
