Rita, they'll be pretty this year, but in years to come, you'll be in LOVE with them! I find the species and smaller varieties often increase faster, but the C.vernus types increase nicely too. My first C.vernus opened today, but most are a week or more from blooming.
Rick, sounds like it was just an off year for a good showing, but the plants themselves sound like they're healthy and happy. I recall years when everything bloomed heavily, but weather greatly diminished the show- either too much rain and cold, or getting hot early and frying the blooms soon after opening. We gardeners must be the most hopeful, positive thinking people on the planet, LOL.
The closed shots of C. estruscus 'Zwanenburg' were taken this morning. Now the sun is bright and they've all opened up and I snapped a couple more-- such a cheery sight!
