This is another species that has many different forms and colors. We don't usually grow bulbs for the beauty of their leaves, but if Oxalis flava didn't bloom, it would be well worth growing just for the leaves. Most forms have leaves that are like palm fronds, but the width of each leaflet varies a great deal, with some forms having wide leaves, other thin thready leaves, and some that are succulent. The one pictured above is not identified so far, but obviously belongs to this group. The leaves are like threads and are succulent.
My absolute favorite, though, is the pink form of Oxalis flava. Not only are the flowers a lovely shade of pink, the leaves are wide and are glaucous, and as they emerge they are ruffled along the edge. It is sometimes called O. lupinifolia, since the leaves look like those of a lupin. As you can see, the flowers emerge before most of the leaves.
A close second to the pink form is the lavender form, also with wide leaflets that are a beautiful grey. This one is much easier than the pink form and multiplies readily.
The many different yellow forms of Oxalis flava are not to be despised, though. They are all lovely and have leaves that are usually narrow and succulent. The variety Oxalis flava v. pectinaria has the narrowest leaves in my collection, with the same brilliant lemon yellow flowers.
