There is no such thing as a blue tulip. You'll find tulips described and pictured as blue in catalogs and on the web, but when spring comes, the blue you longed for will be just another (lovely) shade of lilac, violet or plain old purple. Despite the ever-growing range of tulip colors, blue is still just a hybridizer's dream.
There are no black tulips, though a few varieties come pretty close. They look black on a cloudy day, but with the sun behind them they show their true color: eggplant. We carry Queen of Night. It adds depth to bright colors.
In daffodils, "pink" is a relative term. Some catalogs and websites show daffodils with clear pink or even blue-pink cups, but what you see in your garden is salmon or apricot or peach. Yes, it's pink compared to the usual daffodil colors (yellow, white and orange) and it's beautiful, but baby pink it's not.
All spring-flowering bulbs make roots in the fall, grow and flower in the spring, and then go dormant in summer. The only time to plant them is in the fall (September to December), when the soil is cooling down. If someone has leftover bulbs for sale in spring or early summer, beware: chances are good the bulbs are dry and dead, and even if somehow they are still alive, they are unlikely to flower properly.
