<strong>ERYTHRONIUMS</strong> <strong>IN</strong> <strong>CULTIVATION</strong><br />

<strong>©</strong> <strong>Ian</strong> <strong>Young</strong><br />

<strong>Erythronium</strong> citrinum<br />

<strong>Erythronium</strong><br />

citrinum is one of a<br />

number of<br />

<strong>Erythronium</strong>s that<br />

are basically white<br />

with a yellow<br />

centre.<br />

This would not be<br />

among the first<br />

species I would<br />

recommend to the<br />

regular gardener :<br />

<strong>Erythronium</strong><br />

oregonum and<br />

<strong>Erythronium</strong><br />

<strong>californicum</strong><br />

provide similar<br />

colours and are<br />

more robust garden<br />

plants, however for<br />

the enthusiastic<br />

growers<br />

<strong>Erythronium</strong><br />

citrinum is a<br />

charming species.<br />

<strong>Erythronium</strong> citrinum has white flowers, with some degree of citrus yellow colour towards the centre with matching<br />

white pollen – the filaments are narrow and there are swollen appendages at the base of the petals.<br />

The species that it is most likely to be confused with is <strong>Erythronium</strong> howellii which shares most of the same<br />

features but does<br />

not possess the<br />

swollen<br />

appendages.<br />

<strong>Erythronium</strong> citrinum<br />

<strong>Erythronium</strong> howellii<br />

On the right are<br />

one inner and one<br />

outer floral<br />

segment from both<br />

<strong>Erythronium</strong><br />

citrinum and<br />

<strong>Erythronium</strong><br />

howellii with the<br />

swollen structure<br />

on the former<br />

circled.
