About Lilium 'Conca d'Or'

Lilium 'Conca d'Or' · also called Conca d'Or lily, Oriental trumpet lily · flowering

'Conca d'Or' is a vigorous Orienpet (Oriental x Trumpet) lily with very large, soft butter-yellow blooms shading to creamy-white margins, lightly recurved and richly fragrant in mid to late summer. Tall and robust with sturdy stems, it suits the back of borders and cutting. It tolerates a range of soils but, like all lilies, is acutely toxic to cats.

Plant type: flowering

Watch for — Botrytis (lily disease): Spotted foliage and rotting buds in humid, crowded conditions. Improve airflow, water at the base and remove affected leaves.

The reasons lilium 'conca d'or' isn't blooming

Almost every non-blooming lilium 'conca d'or' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding lilium 'conca d'or' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get lilium 'conca d'or' to flower

Maximise sun. Give lilium 'conca d'or' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for lilium 'conca d'or' and get the feeding right with the lilium 'conca d'or' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Lilium 'Conca d'Or' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full lilium 'conca d'or' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
