I don't think they are developed by Royal Color. To me it looks Royal Color is only a reseller like many others here in Holland with high-end prices. I have good experiences with eurobulb (or there Dutch firm http://www.verberghe.nl/). Opposite to normal where you get 1 bulb these red, white, orange and this year yellow garden are sold as clumps of smaller bulbs. Flowers are smaller as the big hybrids. Mine are about 10cm across. Often 5-6 flowers on one stem. So in one season a lot of flowers. If desired I can send in September some bulbs over from the different garden varieties to the bx.
