Scilla peruviana

In the UK (SE in my Case) This species bulb grows very easily and
increases each year with just a couple of summer months when it is not
visible. If left in the ground it forms a congested clump of numerous
small bulbs after a few years and more or less stops flowering. If
lifted and split up every couple of years you can get each group
flowering regularly on the larger of the bulbs. Any winter frosts make
it look a bit sad but it soon recovers before flowering. Are there ideal
conditions that give more reliable flowering each year? What happens in
the wild; does it form congested non flowering clumps or do much poorer
soils and higher temperatures stop it from multiplying so much? Are we
just too kind to it or is it our long drawn out periods of indifferent
weather to blame?

Brian, still no real frosts so far and very green again after a period
of several weeks drought; weeds and moss replacing some of my lawn turf.
