hybrid plant named ‘LMAggie1’

Abstract

‘LMAggie1’ is a distinctive Agapanthus hybrid seedling selection, which is characterized by evergreen foliage, a short plant height, a short inflorescence height and dark purple flowers.

Description

Latin name of the genus and species: The Latin name of the novel variety disclosed herein is Agapanthus hybrid ‘LMAggie1’.

Variety denomination: The inventive variety of Agapanthus hybrid disclosed herein has been given the variety denomination ‘LMAggie1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Agapanthus hybrid, which has been named ‘LMAggie1’. Its market class is that of an ornamental flowering perennial. Agapanthus, commonly called “lily of the Nile”, is a flowering perennial native to South Africa that forms clumps of dark green strap-like leaves. In summer, umbels rise above the foliage which bear numerous flowers in colors ranging from pale violet to dark purple. Its consistent size and performance, combined with its attractive inflorescences through its hardiness range make it an ideal choice for specimen, borders and mass plantings in any full to filtered sun to shady, low-maintenance landscape or container.

Parentage: The cultivar ‘LMAggie1’ is a seedling selection resulting from the controlled pollination of seed parent Agapanthus praecox subsp. minimus (unnamed and unpatented) and pollen parent Agapanthus hybrid ‘Mood Indigo’ (unpatented) performed at a residence in Lake Mathews, Calif. in 2004. Said seedling was first observed in 2005 and was noted as exhibiting evergreen foliage, a short plant height, and a short inflorescence height like that of the seed parent, but possessing dark purple flowers like those of the pollen parent. Said seedling was isolated for further observation and was subsequently grown and asexually propagated through many generations from 2005 until 2014, at which time it was determined that the characteristics for which it was originally selected were uniform and stable. The new plant was given the name ‘LMAggie1’.

Asexual Reproduction: ‘LMAggie1’ was first asexually propagated by dividing the root-bearing, rhizomatous propagules of the plant (i.e. “division cloning”) in 2005 in Lake Matthews, Calif. and has since been asexually propagated through nine subsequent generations. The distinctive characteristics of the inventive ‘LMAggie1’ variety are stable from generation to generation; clones of the variety produced by asexual reproduction maintain the distinguishing characteristics of the original plant.

SUMMARY OF THE INVENTION

‘LMAggie1’ is a distinctive Agapanthus hybrid seedling selection, which is characterized by evergreen foliage, a short plant height, a short inflorescence height and dark purple flowers.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of a new and distinct Agapanthus hybrid seedling selection known as ‘LMAggie1’. Unless indicated otherwise, the descriptions disclosed herein are based upon observations made in May 2014 of mature ‘LMAggie1’ plants, approximately 12 months of age, grown in-ground at a residence in Perris, Calif. Plants were grown in full sun; fertilized with slow release granular fertilizer and regularly watered with overhead irrigation. No pest or disease measures were taken during production.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘LMAggie1’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 1986 edition. Note that generic color descriptions such as “green” do not exist in the R.H.S. charts and the corresponding R.H.S. colors are quoted.

The distinguishing features and other characteristics of Agapanthus hybrid ‘LMAggie1’ are apparent from the description provided below.

  Comparisons with other Agapanthus.

‘LMAggie1’ is most similar to the seed parent, Agapanthus praecox subsp. minimus, in that both are characterized by evergreen foliage, similar overall plant height, similar inflorescence height and similar flower count. However, there are several characteristics that distinguish ‘LMAggie1’ from the seed parent. The flowers of ‘LMAggie1’ are dark purple (RHS 79B) whereas the flowers of the seed parent are described as a pale violet blue, approximated to violet blue (RHS 92C) on the outer perianth. The flower count of ‘LMAggie1’ ranges from 30 to 45 flowers whereas the flower count of the seed parent is lower, ranging from 20 to 30 flowers. The leaves of ‘LMAggie1’ are 15.5 mm wide whereas the leaves of the seed parent are 12.5 mm wide. The leaf cross section of ‘LMAggie1’ is flat whereas the seed parent is slightly folded adaxially at the midrib. The plant habit of ‘LMAggie1’ is arching whereas the habit of the seed parent is weeping.

‘LMAggie1’ is similar to the pollen parent, Agapanthus hybrid ‘Mood Indigo’, in that both have dark purple flowers and a similar number of flowers per umbel. However there are characteristics that distinguish ‘LMAggie1’ from ‘Mood Indigo’. ‘LMAggie1’ is an evergreen perennial whereas ‘Mood Indigo’ is deciduous. The flower attitude of ‘LMAggie1’ is upward and outward whereas the flowers of ‘Mood Indigo’ are pendulous.

With respect to commercial varieties, there are no varieties known to the breeder that exhibit the combination of dark purple flowers, short foliage height and short inflorescence height of ‘LMAggie1’. There are several Agapanthus cultivars that are described to have dark violet flowers like those of ‘LMAggie1’ however each of these varieties exhibit inflorescences that are taller than that of ‘LMAggie1’: Agapanthus ‘Northern Star’ (U.S. Plant Pat. No. 20,957), is reported to exhibit foliage height of 60 cm and a scape length of 100 cm; Agapanthus ‘Senna’ (U.S. Plant Pat. No. 19,972) is reported to exhibit foliage dimensions of 30 cm tall and over 40 cm wide with an overall height, in flower, of 96 cm; and, Agapanthus ‘Elaine’ (U.S. Plant Pat. No. 7,303) is described to exhibit an overall height, in flower, of 130 cm.
