About Tulipa 'Prinses Irene'

Tulipa 'Prinses Irene' · also called Princess Irene tulip, Triumph tulip · flowering

Plant bulbs in autumn in full sun and free-draining soil for goblet blooms on sturdy 30-35 cm stems.

Mature size: 30-35 cm (12-14 in) tall in flower, with a spread of about 10-15 cm per bulb.

Indoor size vs how big it gets in the wild

Tulipa 'Prinses Irene' is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem. Indoors and in a pot, expect 30-35 cm (12-14 in) tall in flower, with a spread of about 10-15 cm per bulb.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Tulipa 'Prinses Irene' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a balanced bulb fertiliser or bonemeal at autumn planting, then a low-nitrogen high-potash feed as shoots emerge and again after flowering to build next year's bulb. avoid high nitrogen, which encourages leaf at the expense of flowers.
