1 Claim. (Cl. 47-60) This invention relates to a new and distinct variety of Dicentra plant.

The present new variety was first developed by me at Guelph, Ontario, Canada, and was asexually reproduced by me at Guelph, Ontario, Canada by root division.

The new variety was developed in the following manner:

A Dicentra oregana Eastwood plant, as a seed parent, was crossed with a Dicentra exmz'a (Ker) Torrey plant, as the pollen parent. Neither of these parent plants is patented.

Seeds from this crossing were planted in beds in close proximity to each other and allowed to cross pollinate freely. Seeds from this first mass planting and natural cross pollination were then planted in beds in close proximity and exposed to open pollination. Seeds from this second mass planting were planted and the new variety was selected from the resulting seedlings.

The drawing The new variety is illustrated in the drawings in which the large central illustration shows typical leaf and flower stalks of the plant while in bloom, and the three smaller illustrations therebeneath show, from left to right, a single bangle in side elevation, bottom plan view, and front elevation, respectively.

Color references herein are to the Maerz & Paul Dictionary of Color.

The root of the plant The new variety of Dicentra plant has the usual fibrous roots of the usual size for Dicentra plants. The roots are resistant to both wetness and drought, and, unprotected, have withstood temperatures as low as below zero Fahrenheit in Guelph, Ontario, Canada.

The exposed plant structure The exposed part of the plant is herbaceous and bushy, reaching a height of about 14l to 18" with a spread of 16 to 20 when the plant is from two to three years old. The exposed part of the plant is quite symmetrical and regular in outline.

The plant is a vigorous grower. Its foliage dries out at lower temperatures, whether the plant is protected or not, but in general the foliage is resistant to drought and wet seasons. So far as can be observed, none of the plants of this variety has even been damaged by insect pests. The plant produces its best foliage when growing in moderate sun or partial shade in well-drained rich humus soil.

The plant blooms best in a temperate climate preferring a range from Virginia, United States of America, northward to Ontario and Quebec, Canada. It blooms best in a partial shade in a rather wet cool season. The quality of the blooms is best when the plant is growing in a well-drained, though moist, soil. The plant is essentially a cooler climate plant and does best in short daylight. The cutting of the blossoms does not appear to have any effect on the blooming characteristics.

They parts ofthe exposed plant The main stalks of the plant range from oil yellow, comparable to Plate 12-Ll at the top to Sudan brown, comparable to Plate l4-L-12 at the bottom. They range from approximately 12 to 18 in length and have a smooth surface texture. They are grouped and diverge upwardly from the roots, being slightly recurvent at their upper ends.

Foliage The foliage is generally dense and lacey, the leaf arrangement being compound. The leaves are basal. They are abundant and of the usual size. In shape, they are compound pinnate with serrated margins and acute apices, and are tapering at the base. They are of medium thickness with smooth upper and lower faces. On the upper faces they are a green comparable to Plate ZO-K-4. On the underside they are a green comparable to Plate 20-F-3. Their persistency on the plant is excellent.

The leaf stems average from 10 to 12" in length and have a smooth surface texture. They are of medium strength and free from stipules.

Buds and blooms The buds are terminal and supported pendantly. They are of the usual surface texture and have the sepals like those of other varieties of Dicentra plants. They are of medium strength. The present variety blooms very strongly in the spring and again in the fall with intermittent blooming periods between the spring and fall seasons. The blooms are somewhat larger than the blooms of the Dicentra oregana or the Dicentra exz'ma ancestors, being about double the size of the common bleeding heart plant.

The permanence of the blooms on the plant is excellent and when cut is fair. Young plants bear somewhat less abundantly than young Dicentra plants of the variety known as Bountiful and described in Plant Patent No. 1,198 of J une 23, 1953. When the plants are three years old, however, they are as productive of blooms as the Dicentra plant Bountiful.

The genital organs and fruit of the new variety are usual, the seeds being small and reniform.

The plant adapts itself well to various latitudes, climates and soils. It is more robust than either the Dicentra oregana or the Dicentra exima ancestors and, owing to its partial sterility, the plant blooms more profusely and for a longerperiod of time than either of its original ancestors. Its predominate feature, distinguishing it from any of its ancestors and the Dicentra Variety of Plant Patent No. 1,198, known as Bountiful, is the color of the large bangles.

The main body of the owers ranges from a pink, comparable to Plate 5l-C-3 through Plate 51-D-5 to Plate 51-J-5, the bottom outwardly flaring tips or spurs being a greyish-pink, comparable to Plate 47-C-2. The wing-like section formed by the crests of the inner petals and extending forwardly and rearwardly of the bangle at the bottom is a dull purple or violet comparable to Plate 54-H-7. The small triangular portion appearing at the lower tip of the bangle and disposed centrally between the outer petals and exetnding laterally of the bangle, formed by the inner petals adjacent their crests, is a dark greyish-pink, comparable to Plate 47-E-5.

The color of the heart-like cap at the juncture of the stern and the bangle is pink, comparable to Plate 52-G-1. At each side of the bangle, as illustrated in the side elevation at the extreme right in the lower illustrations of 1,594 v 3 f 4 the individual bangles, is a thin purplsh-pink line which Having illustrated and described my new Dicentra extends about half-way down the side of the bangle. This plant, I claim: line is colored purple-pink, comparable to Plate 49-H-7. The new variety of Dicentra plant herein shown and This coloring of the blossom is very distinctive and described.

results in a very attractive blossom and very attractive 6 general tonality of the plant when viewed from a distance. N0 references Cited.
