The famous saffron crocus, Crocus sativus has huge filaments to their anthers which you can harvest as colour & flavouring for
...Crocus chrysanthus ' Spring Beauty' is my top favourite crocus, with buds like a Rembrandt Tulip, the outer petals with a white base, feathered & veined with the deepest violet, the inner revealed when the flowers open, a lovely soft mauve. Crocuses are often the first flowers in a garden & feel like the true cheerleaders of spring. Delicate, yet easy to grow, lovely closed up as a goblet & even lovelier, fully starily open. They will cheer up your February & March garden, at a generally grey time of year.
