I remember planting theseErythronium bulbs , many years ago.I was looking forward to many multiplying clumps . I planted two : 'Pagoda' and this one 'Dens -canis' . 'Pagoda' bloomed the first year and every year since but never really flourished. Dens-Canis would always appear with it's mottled little leaves ,but never a bloom.. Last year I dug the bulbs up and plopped them under a fat clump of Hellebores. Still no blooms. But, as I was cutting the old foliage from the Hellebore , what should appear ….these sweet blooms!
