Cucurbita pepo species


  • Annual
  • Tromboncino, also known as zucchini rampicante is an Italian heirloom squash that derives its name from its fruits that are shaped like a trombone - it looks like a butternut squash with an extra extra long neck.
  • Similar to the butternut, the whole neck is solid and there is only a small seed cavity at the base.
  • All parts are edible and it has a tender, buttery taste with a hint of nutty artichoke flavor.
  • The Tromboncino is a half hardy annual climber with large, ornamental leaves that are liberally splashed with silver.
  • It does not need much ground space and is ideal for growing up an archway or trellis, to allow room for the long fruit to grow and hang freely.
  • The fruit can weigh up to 2 to 3kg each - be sure that your trellis can handle the weight.
  • However, it can also be left to sprawl over the ground and will then produce curvy fruits.
  • The Tromboncino squash is incredible versatile and can grow up to 1 meter if allowed to mature.
  • It can be used both as a summer squash and a winter squash as it has great keeping abilities.
  • The fruit must be picked regularly to prolong the harvest.
  • It can be harvested young at about 25cm long and be eaten as a baby marrow or zucchini.
  • For a winter squash, allow it to stay on the vine until it turned beige like a butternut, and the skin has hardened.
  • Harvest all before the first frost.
  • The rind peels easily.
  • Tromboncino needs rich, well-fertilized soil in full sun and plenty of watering in dry weather.
  • Unlike other squash, Tromboncino has the advantage that it is insect resistant to squash vine borers and also resistant to mildew.
  • To propagate:
  • Soak the seed overnight (optional) and sow under cover up to a month before the last frost date.
  • Push the seed, on its side (to prevent it rotting), 2-3cm deep into pots filled of compost.
  • When the plants have 5-6 leaves, they can be transplanted in the garden - 90cm apart in each direction.
  • Alternatively, it can be sown direct in spring after all danger of frost has passed.
  • Days to maturity are 80 to 100 days.

Culinary Uses

  • Tromboncino squash is similar to butternut and is perfect for steaming, grilling, roasting, frying, or sliced raw in salads.
  • The Italians use it in gnocchi and to stuff ravioli.
  • Like with other pumpkin, the seeds are edible and it can be eaten raw or roasted.
