Skip to: Description  ·  Claims  · Patent History  ·  Patent History

Latin name of the genus and species of the plant claimed: Calendula maritima.

Varietal denomination: ‘CDAZ0001’.


The present invention comprises a new Calendula, botanically known as Calendula maritima, and hereinafter referred to by the variety name ‘CDAZ0001’.

‘CDAZ0001’ is a product of a planned breeding program. The new cultivar has orange color with a gold center flower color, single flower form, and mound spreading plant habit.

‘CDAZ0001’ originated from selfing a hybrid plant ‘GUC0266-1’ made in a greenhouse in June of 2010 in Gilroy, Calif., United States. This ‘GUC0266-1’ plant was developed in our breeding program, unpatented, with orange flower color, double flower, and overall larger size than that of ‘CDAZ0001’. ‘CDAZ0001’ differs from its sibling ‘CDAZ0002’ which has a deep apricot orange flower and a double flower form.

The resultant seed was sown in January 2011 in a greenhouse in Gilroy, Calif.

‘CDAZ0001’ was selected as one flowering plant within the progeny of the stated cross in March 2011 in Gilroy, Calif.

The first act of asexual reproduction of ‘CDAZ0001’ was accomplished when vegetative cuttings were propagated from the initial selection, this initial selection took place on Mar. 15, 2017 in Gilroy, Calif.


Horticultural examination of plants grown from cuttings of the plant initiated in April, 2012 in Gilroy, Calif., and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CDAZ0001’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CDAZ0001’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar has not been applied for. ‘CDAZ0001’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained ‘CDAZ0001’ directly from the inventor.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Calendula as a new and distinct variety.


The accompanying photographic drawings show typical flower and foliage characteristics of ‘CDAZ0001’ with colors being as true as possible with an illustration of this type

The photographic drawings show in FIG. 1 a close view of flower of the new variety and in

FIG. 2 a flowering plant from an outdoor trial.

The aforementioned photographs: FIG. 1, as well as FIG. 2, were taken in October 2016 both showing a plant from the same natural outdoor trial in Gilroy, Calif. These plants were about 18 weeks of age. One rooted cutting per pot had been planted in a one gallon pot, not pinched in week 22. Plants started flowering end of July.


The measurements were taken in Gilroy, Calif. in May 2017 on the plants from the aforementioned trial.
