Growth—

The variety nana is generally found on neutral to acid soils, it avoids rocky subsoils and is prevailingly calclfuge. The variety carnescens is calcicole, being found on limestone rubble, caliche, or gypsum[1]. This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[2].

Propagation

Seed - sow in early spring in a greenhouse. The seed has a hard seedcoat and benefits from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer[3].
