Getting it to bloom

Why won't my white double camellia bloom? (and how to make it flower)

Also called white double camellia, Alba Plena camellia, White Formal Double Camellia (Camellia japonica 'Alba Plena').

About white double camellia

Camellia japonica 'Alba Plena' · also called white double camellia, Alba Plena camellia · flowering

'Alba Plena' is one of the oldest Camellia japonica cultivars in Western cultivation, prized for its perfectly formed formal double pure white flowers produced from late winter through spring. The blooms are tightly layered with no visible stamens. A slow-growing, compact evergreen shrub well suited to containers, courtyards, and sheltered acid-soil borders.

Plant type: flowering

Watch for — Petal browning: White flowers are particularly prone to browning from frost, rain, or direct sun. Site in a sheltered position facing east or north, and avoid overhead watering onto open blooms. Dead-head promptly to maintain appearance.

The reasons white double camellia isn't blooming

Almost every non-blooming white double camellia traces back to one of these, roughly in order of how common they are:

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

Feeding white double camellia 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 white double camellia to flower

  1. Maximise sun. Give white double camellia the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. 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 white double camellia and get the feeding right with the white double camellia 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

white double camellia 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 white double camellia care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

white double camellia blooming — frequently asked questions

Why won't my white double camellia flower?

white double camellia blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make white double camellia bloom?

Give white double camellia the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.

When does white double camellia normally bloom?

white double camellia flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

What should I do with white double camellia after it flowers?

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.
