Undraining

Hesiod speaks of the mysterious region where 'dark earth, misty Tartarus, the undraining sea, and the starry heaven all have their sources and extremities in order', and in Homer's account of the division by lot among the sons of Kronos 'everything' is divided up into the four portions, earth, broad heaven, hoary sea, and misty darkness.

If heavy undraining soil spoils your plant selection, grow 'Passion Mix' in containers with a soilless mix.
