Sea of pink

Oenothera speciosa Pink Evening Primrose
I am always doing trials of various plants to see how they grow under fairly harsh conditions, either in poor soil or under a no water no fertilizer regime. This perennial from Mexico has loved the hot dry conditions of this spring. It is a bit of a spreader though and sends down underground creeping stems and pops up further away from where you planted it Flowering stems shoot up to about 30cm and they support each other. This does not happen when it is grown as a pot plant and it tends to flop about. Not much good when you are growing plants for sale as they tend to look less than robust or just plain untidy. This is a good plant for sunny dry embankments but would need to be sheared down at the end of the growing season and kept contained. It dies down over winter so its growing place could be covered in mulch or compost and it will happily grow back through the covering in spring.
