The Olympics are one of the most spectacular mountain groups with a phenomenal range of plants - these are pics of three of the bulbs.
Lilium columbianum is common in the Pacific North West ( and it gets as far as CA, ID and MT) but that doesn't make it any the less pretty.
Erythronium montanum is another Pacific North West speciality (just OR, WA and BC)
Both of these like the grassy slopes but the last likes quite a different habitat. Allium crenulatum (the Olympic onion) is very much confined within OR, WA and BC and obviously manages in a niche of shifting shale that other plants fail to cope with.
In the garden I find most Alliums to be a nuisance but this is made so attractive by the framing of the bare shale.
