Yes, mine was hybridized using the lighter colored caudatum sanderae, so the blooms are very large bulbous and turn more golden as they age. The blooms are very long lasting, about 2 months if I'm not mistaken. Yes, the petals continue to grow until they reach a little over 12 inches. My plant is a reliable bloomer and has spiked almost every year, sometimes 2 spikes in a year.

My Grande is also a multifloral variety. Is yours a sequential or a multifloral?
