   Shows as stretched growth with long gaps between leaves, small pale new leaves, loss of variegation, leaning hard towards a window, and — in flowering plants — foliage without flowers. It is the commonest reason an indoor plant fails to thrive while appearing to be watered and fed correctly.

   Points towards it

   • · indoors is where the light falls short — the same plant in a conservatory or outdoors for the summer flowers far more readily
   • · the plant is healthy and growing and simply does not flower, which is what a light shortage looks like on a species that needs a great deal of it
   • · it keeps producing large new leaves, so growth is plainly not the constraint

   Argues against it

   • · a plant kept persistently dry has a simpler reason for not flowering, and this one needs steady water in growth
   • · a recent repot suppresses flowering in its own right on this plant, which flowers best when its roots are crowded — that is a different diagnosis with the same appearance

   Judge the light where the plant actually stands, then count its age. A bird of paradise wants the brightest position in the house — a south or west window with direct sun for part of the day — and will not flower in the bright indirect light that suits most foliage plants. It also needs to be mature: a plant under four or five years old, or one grown from seed, has not flowered yet rather than failed to.

   What to do now

   Move it to the brightest window you have and stand it outside in full sun from June to September, which is the single change that most often brings one into flower. Leave it in its pot — it flowers best when crowded and repotting sets it back a year or two — and feed monthly through the growing season with a balanced feed rather than a high-nitrogen one.

2. Not old enough to flower

   A plant that will not flower because it has not finished being a juvenile. Woody climbers are the classic case — a seed-raised wisteria may take fifteen years and a grafted one three — and it is the answer nobody wants, because the correct action is to do nothing and the correct timescale is years.

   Points towards it

   • · a healthy young plant growing well and simply not old enough shows nothing wrong in its care, and a recent repot actively postpones flowering on this species
   • · the whole plant is in a vegetative stage rather than any part of it being damaged
   • · this is an indoor container plant in the UK

   Argues against it

   • · saturated compost gives a reason for a plant not to flower that has nothing to do with its age
   • · cold damage to the developing flower spike is a specific injury rather than a question of maturity

   Work out the plant's age and count its leaves before changing anything. A strelitzia raised from seed will not flower for roughly four to six years whatever is done to it, and a plant that has not yet made a substantial clump — fewer than about six or eight full-sized leaves — is not yet flowering size. Ask how big the pot is as well, and be suspicious of a recent potting-on: this plant flowers best when the roots are crowded, so a strelitzia that has just been given more room has been given a reason to grow leaves instead. Healthy growth and good leaf colour with no flowers is the picture of a plant that is fine and young.

   What to do now

   Wait, and leave the pot alone — the single most useful thing you can do is stop potting it on, because this plant flowers when its roots are congested and repotting resets that. Give it the brightest position you have, including some direct sun, and stand it outdoors in a sheltered sunny spot over the summer if you can, bringing it back in well before the first frost. Keep it comfortably watered in growth and much drier through the winter, and feed monthly through spring and summer only. Beyond that the answer is time, and a plant of the right age in the right light generally gets there on its own.

Narrow it down

This page lists everything at once, which is the right shape for reading and the wrong shape for deciding. The interactive tool asks one question at a time, starting with whichever would separate these causes fastest, and stops as soon as further answers would not help.

Opens with the plant and the symptom already set. Nothing you answer is stored or sent anywhere — the answers live in the address bar and nowhere else.

What this does not cover

These are the causes GrowingHQ holds rules for on bird of paradise — not every cause there is. Where several problems look alike, the honest answer is often that they cannot be told apart by eye, and a page that named one would be guessing. If none of the above fits, the general healthy growth but no flowers page lists causes across all plants, and the Bird of paradise profile lists the problems it is prone to.
