Can Iron Cross live in sandy soil?

[Plantium]

Can Iron Cross (clover) live, thrive and divide its bulbs, if the plant is planted in sand taken from the beach?

Try it...but my guess is no. Beach sand is generally very high in salt content...clover does not like salt.

However, clover will most definitely grow in sandy soils...maybe not as good as heavier soils. I have about 200 acres of it with clover patches everywhere.

It's not fully clear which plant you are referring to, but there is a plant commonly known as Iron Cross Wood-sorrel (Oxalis tetraphylla 'Iron Cross') which is grown for its ornamental, four-parted leaves, with dark purple centers. Though not a true Clover (Trifolium), it is often sold as a "Four-leaved 'Lucky' Clover" plant because of the superficial resemblance of the leaves.

This plant would not grow well in pure sand, but sand could certainly be a component of a well-draining potting mix that would be beneficial for this plant. Beach sand taken directly from the intertidal area of a beach would likely be coated with some harmful salts (Sodium chloride, etc.) but after a soaking and leaching with fresh water, the salt content would likely be much reduced.
