Title: Aechmea plant named &#39;del cielo&#39;

Description:
Botanical designation:  Aechmea fendleri×Aechmea dichlamydea trinitensis.    
     Cultivar denomination: ‘DEL CIELO’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct  Aechmea plant , botanically known as  Aechmea fendleri×Aechmea dichlamydea trinitensis  and hereinafter referred to by the cultivar name ‘Del Cielo’. 
     The new  Aechmea  plant is a naturally-occurring whole plant mutation of the  Aechmea fendleri×Aechmea dichlamydea trinitensis  ‘Del Mar’, disclosed in U.S. Plant Pat. No. 13,421. The new  Aechmea  plant was discovered and selected by the Inventor from within a population of plants of ‘Del Cielo’ in a controlled greenhouse environment in Princeton, Fla. in 2005. 
     Asexual reproduction of the new  Aechmea  plant by offsets in a controlled greenhouse environment in Princeton, Fla. since 2005 has shown that the unique features of this new  Aechmea  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Aechmea  have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Del Cielo’. These characteristics in combination distinguish ‘Del Cielo’ as a new and distinct  Aechmea  plant:
         1. Upright and outwardly arching growth habit.   2. Creamy white, light green and green variegated leaves with green-colored margins and creamy white and yellow green-colored longitudinal stripes.   3 Inflorescences held upright and above the foliar plane on strong red-colored scapes.   4. Tightly branched inflorescences with dark violet blue-colored petals and lighter violet blue-colored sepals.   5. Long-lasting inflorescences.       

     Plants of the new  Aechmea  differ from plants of the parent, ‘Del Mar’, primarily in leaf color as plants of ‘Del Mar’ have solid green-colored leaves. 
     Plants of the new  Aechmea  can be compared to plants of  Aechmea fendleri×Aechmea dichlamydea trinitensis  ‘America’ , disclosed in U.S. Plant patent application Ser. No. 14/545,629. Plants of the new  Aechmea  and ‘America’ differ primarily in the following characteristics:
         1. Plants of the new  Aechmea  are more compact and have shorter leaves than plants of ‘America’.   2. Inflorescences of plants of the new  Aechmea  are more dense than inflorescences of plants of ‘America’.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown in 20-cm containers during the summer in a polypropylene-covered shadehouse in Princeton, Fla. During the production of the plants, day temperatures ranged from 28° to 30° C., night temperatures ranged from 18° C. to 22° C. and light levels ranged from 2,200 to 3,200 foot-candles. Plants were 14 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
