1910, Iris Stylosa, Failing to Flower

The Garden p.110, March 10, 1910

Irls stylosa failing to flower.— It would be interesting to know if Iris stylosa has generally failed to bloom this winter. Last winter I had quantities of bloom from November to April, whenever the weather was the least mild; this winter I have not had a bloom. I have about forty clumps. I attribute it to the wet and cold summer, the plants not having had the baking they require. — C. G. 0. Bond, Churl, Surrey.

Iris stylosa failing to flower.— On page 110 Mr. C. G. 0. Bond remarks upon the failure of Iris stylosa to flower in Surrey. Here in South Devon it has flowered very badly this season. As a rule, we get our first flowers in the last week of October and the plants remain in bloom until April; but this season the first blossoms did not expand until early in January, doubtless owing to the damp and dull summer. This was not the case merely in my own garden, but in every one in the district. In a neighbouring garden, where over 5,000 blooms were out last season, none was produced until .January in the present year. Since they commenced to flower, however, they have bloomed well, and dozens might have been picked any day from the middle of January until now, and the plants show no sign of ceasing to flower. Several plants that were shifted in November, and from which I thought I should get no blooms, have been flowering well since mid-January. Mr. Bond does not say if his plants are now bearing blossom, as ours are doing freely. — Wyndham Fitzherbert, Kingswear.

Iris stylosa failing to flower.— In reference to the note on page 110. I think the conclusion arrived at, viz , that the plants did not have the baking required to ripen them, is in the main correct. However, there may be other influences which bear materially on this matter. The most floriferous plants of Iris stylosa or unguicularis that I have seen were planted in a loamy soil at the base of a south wall. Some plants on a west border, which were under the writer's observation for several years, produced only a few flowers. These were not planted at the foot of the wall, but 3 feet or more from the same and in the rich soil of an old kitchen garden. In another instance the plants were growing at the foot of a south wall, on which was trained a standard Pear tree, and the plants produced few flowers. The Pear tree was of considerable age, the spurs being 1 foot or more in length. Did the foliage of this tree afford too much shade, or was the drip after rain detrimental to the Iris ? — Colin Ruse.
