|Last year I bought a variety of Achimenes bulbs. Only one of the three colors bloomed. Out of red, purple, and pink, only the pink bloomed. Is there a reason why?|
|Achimenes are tender perennials, native to the tropics, and are usually treated as annuals, or grown in greenhouses. If you grow them outdoors, plant the rhizomes in the spring, about 1 inch deep in moist peatmoss and sand. Keep them well watered and in the shade. In the fall, dig the rhizomes, dry, and store in a cool place over the winter. In the spring replant them.|
If yours didn't bloom, perhaps the environment wasn't quite right, or the plants were too immature. Dig the rhizomes now, store them until spring, and then plant them again.
They may bloom next year.
