1 Claim.

This discovery relates to a new and distinct variety of delphinium, a hybrid of Delphim'um nudicaule, but differing in material respects from its parents.

The variety originated as a chance seedling, the result of a cross of Delphinium nudicail-le and an unknown variety, said seedling being superior to and different in color, vigor or growth, size of flower spike, foliage, root system and method of reproduction from its parents. It is also characterized as to novelty by its earliness and floriferousness.

The novelty and distinctiveness of this new plant variety may best be understood by comparison with its parent, Delphinium nudicaule. First and most important is the color of its flower, which has pink sepals and violet petals, whereas the parent variety has orange sepals and yellow petals.

In vigor of growth this new variety has the true hybrid vigor and grows from 4 to 6 feet tall, whereas Delphim'um nudicaule grows only from 1 to 1% feet, and the size of the flower spike differs in that it 'is proportionately larger and fuller.

It may be noted further as regards its habit of growth that instead of the plant top disappearing and the plant going dormant for quite a while in the summer, as is the habit of nudicaule, the new variety immediately starts the new shoots even before the flower is through blooming, and it is never without foliage.

In the section of northern New York, the variety blooms three and sometimes four times and is very frost resistant at the end. This habit greatly enhances the value of the variety as a garden plant.

The foliage of the new variety differs in. form and also in texture, being non-succulent or slightly succulent, and the form varies slightly in contour.

It is also notable that the new variety has a diiferent root system many fibrous roots, whereas the Delphinium nudicaule has a fleshy root.

The new variety has been asexually repro duced and comes true to form, but thus far it has not been possible to reproduce it from seed, thus marking another point of distinctiveness. It has been known to seed in very rare instances, but

the seedlings were entirely diiferent from the parents.

The following is a detail description of the new variety, the color terminology being in accord with Ridgways Color Standard:-

Seed.The variety is self sterile and although repeatedly tried has not reproduced itself from seed.

I claim:

A new and distinct variety of delphinium, characterized by the form, and habit of growth of the plant, its root system, and the pink color of its blossom, substantially as shown and described.
