The most spectacular displays right now in my garden are the narcissus. I have planted the hillside behind my house with bulbs each fall (except last year) and the result is clusters of flowers scattered over the slope. I thought I was planting many bulbs but clearly I could have multiplied my planting by 5 or maybe ten to get really spectacular results. Still what I have is beautiful.
Last year I was thinking of planting some whites. I am still thinking. When I see all the yellow flowers, it seems that white would detract. Maybe just a few.
I also planted lots of muscari, thinking how nice the blue flowers would be against the yellow. I don't know how they do it for the pictures but in my garden the muscari bloom after the narcissus and they are dinky little things. I probably need to read the fine print.
