Cultivation details

Prefers a sunny position in a well-drained rich soil with abundant moisture[1, 175]. Succeeds in ordinary garden soil[175]. Plants are found in dry soils in the wild so this suggests that they will be better off in a dry soil in this country[K]. A perennial plant, it is not very hardy in Britain, tolerating temperatures down to about -5°c, and is perhaps best grown as an annual. A climbing plant, supporting itself by means of tendrils[219].

It is April 2005. Due to historic rain Marah Macrocarpus is all over San Diego. Most significant is the abundance of the green, spikey fruit. As to "edibility" I have found that the "meat" of the seed is quite edible but requires the sloughing off of the green seed coat. That taste begins sweet and finishes with a bitterness, mostly due to the oil. Seeds that are sun-dried still retain the meat but there is more oil when pressed and the resulting paste is like Marzipan in consistency.
