Abstract
Description
[0001] Latin name of the genus and species: Crassula platyphylla.
[0002] Cultivar denomination: ‘HALO’.BACKGROUND OF THE INVENTION
[0003] The new cultivar, Crassula ‘Halo’, is the result of a naturally-occurring branch mutation of the unnamed Crassula platyphylla. The new cultivar, Crassula ‘Halo’ was discovered by the inventor in March of 2022 in a commercial greenhouse in Vista, California.
[0004] Asexual reproduction of the new cultivar ‘Halo’ was first performed in Vista, California, at a commercial greenhouse, by vegetative cuttings in May 2022. ‘Halo’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.SUMMARY OF THE INVENTION
[0005] The cultivar ‘HALO’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.
[0006] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘HALO’. These characteristics in combination distinguish ‘HALO’ as a new and distinct Crassula cultivar:
[0007] 1. The new cultivar Crassula platyphylla ‘Halo’ forms heavily offsetting variegated plants.
[0008] 2. Crassula platyphylla ‘Halo’ exhibits gracefully arching branches of delicate green, margined in creamy yellow splashes.
[0009] 3. The attractive clustering of Crassula platyphylla ‘Halo’ is particularly suited to use in patio mixed plantings as the variegated leaves enhance the other colors.
[0010] 4. Crassula platyphylla ‘Halo’ branches heavily as a young plant, resulting in enhancement of propagation in a commercial nursery environment and a fuller product at an earlier age.
[0011] Plants of the new cultivar ‘HALO’ are similar to plants of the parent in most horticultural characteristics, however, plants of the new cultivar ‘HALO’ differ in the following;
[0012] 1. Crassula platyphylla ‘Halo’ is a variegate, whereas the parent variety, Crassula platyphylla is not.
[0013] 2. Crassula platyphylla exhibits leaves that blush reddish in strong light, whereas Crassula platyphylla ‘Halo’ displays somewhat elongated green leaves with marginal splashes of creamy yellow.
[0014] 3. Crassula platyphylla ‘Halo’ displays a larger, more graceful morphology than does Crassula platyphylla. COMMERCIAL COMPARISONS
[0015] Plants of the new cultivar ‘HALO’ are comparable to the commercial cultivar Crassula platyphylla ‘Daydream’, U.S. Plant Pat. No. 33,928. The two Crassula cultivars are similar in most horticultural characteristics; however, the new cultivar ‘HALO’ differs in the following:
[0016] 1. Crassula platyphylla ‘Halo’ produces olive green leaves, margined with creamy yellow splashes, whereas Crassula platyphylla ‘Daydream’ U.S. Plant Pat. No. 33,928 produces leaves with more slender apple green midstripes, margined with white and blushed in rose under certain conditions.
[0017] 2. Crassula platyphylla ‘Halo’ displays a somewhat more lax morphology than does Crassula platyphylla ‘Daydream’.
[0018] Plants of the new cultivar ‘HALO’ can also be comparable to the unpatented, unnamed cultivar of Crassula platyphylla found in the horticultural market. The two Crassula cultivars are similar in most horticultural characteristics; however, the new cultivar ‘HALO’ differs in the following:
[0019] 1. Crassula platyphylla ‘Halo’ is a variegated plant, whereas Crassula platyphylla is not.
[0020] 2. Crassula platyphylla exhibits green leaves, blushing red in full sun, whereas Crassula platyphylla ‘Halo’ displays somewhat olive leaves, margined in creamy white splashes.
[0021] 3. Crassula platyphylla is a bit more compact growing than Crassula platyphylla ‘Halo’, which produces a more flowing morphology.BRIEF DESCRIPTION OF THE PHOTOGRAPH
[0022] The photograph was taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living cultivar, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of the new cultivar Crassula ‘Halo’. The accompanying figure illustrates in full color a plant of Crassula ‘Halo’, at about 9 months, grown at a nursery (approximately 2500 foot candles) in Vista, California in an 8-inch pot.DETAILED BOTANICAL DESCRIPTION
[0023] In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 edition, except where general terms of ordinary dictionary significance are used.

No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Natural light conditions were approximately 2500 to 3000 fc of light. Measurements and numerical values represent averages of typical plant types.
