|For the past three years, I've been trying to get Burpee Moonflowers to grow from seed. I've always had great success with Burpee's Morning Glories, but none with their Moonflowers. This year was my first spring with sprouting Moonflowers. It took 2 months for a flower to appear (With mild fertilizer) and upon waiting for a bud to open at dusk, I had no success. I the morning however, I had beautiful Morning Glories where my Moonflowers were. I've got them planted in very large terra cotta pots under a lattice frame that gets direct sun. I planted both Moonflowers and Morning Glories and I know the difference between the seeds. What could have happened?
