Not every garden has room for drifts of daffodils or towering alliums. Rockeries, gravel beds and the edges of paths call for something in scale — and a handful of dwarf bulbs do that job perfectly.
Iris danfordiae
Iris danfordiae (
buy from Thompson & Morgan →) is a miniature bulbous iris flowering in February, only 10-15cm tall, with bright yellow blooms that are easy to overlook until you're at ground level admiring a rockery.
Ipheion
Ipheion Mixed (
buy from Thompson & Morgan →) produces star-shaped flowers in soft blues and whites over grassy foliage, and slowly spreads to form a low mat — useful for softening the gaps between rocks or paving.
Planting conditions
Both need sharp drainage above all else — plant in gritty, free-draining soil or raised beds, 5-8cm deep, in full sun. Waterlogged winter soil is the main cause of failure for rockery bulbs.
Scaling the same idea to orchids
The same small-space logic applies to hardy orchids: compact genera such as
Pleione suit a trough or alpine bed just as well as these dwarf bulbs suit a rockery.
