Naturalising bulbs: plant once, flower every year
Most garden tulips peak in their first spring. One group of bulbs does the opposite: they settle in, spread, and get better every year — with zero maintenance.
What does naturalising mean?
Naturalising bulbs are varieties and species that thrive so well they behave like wild plants: returning every year, setting seed or offsets, and slowly forming bigger colonies. Species tulips like Tulipa clusiana 'Lady Jane' and the woodland tulip (Tulipa sylvestris) are among the best — alongside crocuses and daffodils, landing in the shop later this season.
Position: imitate nature
The key is drainage and peace. Plant in gritty, lean soil in full sun (most species tulips) or under deciduous trees (woodland tulip) where bulbs get spring sun before the canopy closes. Avoid spots that are watered and fed all summer — these bulbs want a dry, warm summer rest.
Planting in the lawn
Scatter a handful of bulbs and plant them where they land — it gives the most natural look. Lift a flap of turf with a spade or use a bulb planter, set the bulb 10 cm deep, and replace the turf. Most important of all: don't mow until the foliage has died down completely in June. The leaves recharge the bulb for next year's flowers.
Patience pays
Not every bulb flowers the first spring — completely normal for species like the woodland tulip, which spend a year settling in. From the second and third year the colony takes off. Plant generously — 25-50 bulbs per square metre; what looks excessive in the bag disappears in the grass.
