Gardeners' Notes:

Have just seen that my Mariposa Autumn iris has big fat buds, about to flower and it is only 8 February! We are in the UK in the Midlands. Is this unusual? It was new to my garden last year and did not flower, even in the Autumn. Now it is showing very early, so I hope the weather doesn't turn too bad.

Although I give this iris a positive rating, it seems to rebloom late in the fall and consequently the blooms are frozen. This is the first spring bloom I've had in three years because of the late rebloom. With that said, it is a nice iris; and its parentage from Jesse's Song is readily seen. Colors are more pronounced in sunlight. The following information is from the AIS Check List database: "(Richard Tasco, R. 1999), Sdlg. 92-25-06-RE. TB, 32" (81 cm), EM & RE "S. rosy violet, white showing in center; style arms rosy violet, edges lemon yellow; F. white ground, rosy violet band; beards white base, hairs tipped violet at end, tipped gold in throat; lightly ruffled; slight sweet fragrance. Jesse's Song X Earl of Essex Superstition 1999 "

Lovely as it is - this may rebloom too well. It bloomed itself out (until it was all gone) for me.
