Sciadopitys verticillata 'Ossorio Gold' · also called Ossorio Gold Japanese Umbrella Pine, Gold Umbrella Pine · flowering

Ossorio Gold Umbrella Pine is a slow-growing, golden-foliaged cultivar of the ancient Japanese Umbrella Pine, with whorled, thick, glossy needles that glow bright gold-yellow in full sun. A rare and prized specimen conifer, it suits sheltered garden positions with rich, moist soil. It is not listed as toxic by the ASPCA.

Plant type: flowering

The reasons ossorio gold umbrella pine isn't blooming

Almost every non-blooming ossorio gold umbrella pine 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 ossorio gold umbrella pine 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 ossorio gold umbrella pine to flower

  1. Maximise sun. Give ossorio gold umbrella pine 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 ossorio gold umbrella pine and get the feeding right with the ossorio gold umbrella pine 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

Ossorio Gold Umbrella Pine 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.
