The plant that is popular with my small family for window boxes right now is Crocosmias. They are very unusual plants to keep in window boxes but I like them. For most of the year our Crocosmia plants are just plain looking reeds. Then in August they sprout a shoot and open several bright orange flowers. To me they are wonderful, they are just the right size for window boxes, they are very robust and even stay green for several weeks when the frost arrives, even if they die you know they will regenerate next spring because they are bulb plants. You need to look them up on the internet to see what they look like.
I was just wondering how long they will remain a family favourite plant? Will my descendents have Crocosmias growing in window boxes? Will they breed them into better plants? Perhaps my descendents will grow Crocosmias that produce flowers all year. I don't know.
The dead leaves of Crocosmias quickly turn into soil and I like the look of the Reeds. Some people keep tulips in their window boxes, others keep Daffodils, we keep Crocosmias and are slowly breeding them. Selecting the best flowers to keep for the following year.
