Erythronium dens-canis

I have three clones of Erythronium dens-canis, all purchased as bulbs 
from European sources. The most vigorous is one called 'Rose Queen', and 
there is another pink and a white one. I've had them for more than ten 
years and they increase well in a sandy, acidic soil on a moderate 
slope. They were in light shade of a deciduous tree until a few weeks 
ago, when the tree was destroyed by an ice storm. However, I think 
they'll continue to do well because they still get afternoon shade from 
a neighbor's high (though not so high as before the ice storm) oak 
trees. Robust, even invasive Paeonia daurica also shades part of their 
area in summer. The erythroniums flower heavily and are in full bloom 
now. Other plants that flourish in this planting space include Gentiana 
acaulis and G. septemfida, and some of the more sun-tolerant dwarf 

I water the bed about once a week in summer with a useful sprinkler that 
produces a fine spray from a pipe about 6 ft/2 m tall. I now have half a 
dozen of these sprinklers in places where the irrigation has to get 
above shrubs or tall perennials. They have an easily set two-pronged 
spike, they take up almost no room, and the copper is not visually annoying.

A friend shared a plant he said was locally  (Ireland) called ‘Old Ugly’ that was his most reliable blooming variety. In over a decade is has bloomed 2 - maybe 3 times. This year is a blooming year . Not spectacular, but OK.
