Bulbs of the Tigridia
This large tigridia bulb is developing a cluster of small offshoots. Each of these little bulbs will produce a plant duplicating almost absolutely the original parent form. There is no such range of variation among plants grown from bulbs as among those grown from seeds. The bulb of the tigridia has exceptional interest because it is edible.
