plant ‘ALTBLOOM’

A new and distinct cultivar of Agapanthus plant named ‘ALTBLOOM’ is disclosed, characterized by a dwarf growth habit, early blooming and large inflorescences resulting in more flowers per plant. The new variety is an Agapanthus, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Agapanthus hybrid.

Variety denomination: ‘ALTBLOOM’.

BACKGROUND OF THE INVENTION

The new Agapanthus cultivar is the product of a planned breeding program conducted by the inventor, Peter Lim. The open pollination resulting in this new variety was made in July of 2013 at a commercial nursery in Vista, Calif.

The seed parent is the unpatented Agapanthus ‘Barley Blue’. The pollen parent is an unnamed, unpatented proprietary Agapanthus. The new variety was identified and selected as a potentially interesting selection on Jun. 30, 2017, at a commercial nursery in Vista, Calif.

Asexual reproduction of the new cultivar ‘ALTBLOOM’ was first performed in March of 2017, in Vista, Calif., by tissue culture and division. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ALTBLOOM’ 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.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ALTBLOOM’. These characteristics in combination distinguish ‘ALTBLOOM’ as a new and distinct Agapanthus cultivar:

  • 1. Dwarf size.
  • 2. Early blooming.
  • 3. Large inflorescences.
  • 4. More flowers per plant than typical of dwarf Agapanthus.
  • 5. Light blue flowers.
  • 6. Strong flowering stems.

PARENT COMPARISON

Plants of the new cultivar ‘ALTBLOOM’ are similar to the seed parent ‘Barley Blue’, in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:

  • 1. The new variety has a much shorter flowering stem than the seed parent.
  • 2. The new variety blooms earlier than the seed parent.
  • 3. Flowers of the new variety are a darker blue color than the seed parent.
  • 4. Flowers of the new variety have a significant purple vein in the center of the petal, while flowers of the seed parent do not.

COMMERCIAL COMPARISON

Plants of ‘ALTBLOOM’ are similar in some horticultural characteristics to the variety Agapanthus ‘Peter Pan’, unpatented. The new variety, however, differs in the following:

  • 1. ‘ALTBLOOM’ blooms earlier than ‘Peter Pan’.
  • 2. ‘ALTBLOOM’ has a shorter stem than ‘Peter Pan’.
  • 3. Flowers of ‘ALTBLOOM’ are a darker blue color than ‘Peter Pan’.
  • 4. Flower clusters of ‘ALTBLOOM’ have more flowers than those of ‘Peter Pan’.
  • 5. ‘ALTBLOOM’ has thicker stems than ‘Peter Pan’.

Plants of ‘ALTBLOOM’ are similar in some horticultural characteristics to the variety Agapanthus ‘Little Galaxy’, application Ser. No. 16/873,015. The new variety, however, differs in the following:

  • 1. ‘ALTBLOOM’ blooms earlier than ‘Little Galaxy’.
  • 2. ‘ALTBLOOM’ has a larger flower cluster than ‘Little Galaxy’.
  • 3. ‘ALTBLOOM’ has a thicker stem than ‘Little Galaxy’.
  • 4. ‘ALTBLOOM’ has larger leaves than ‘Little Galaxy’.
  • 5. ‘ALTBLOOM’ produces many more flowers than ‘Little Galaxy’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘ALTBLOOM’ grown in a commercial hoop-house in Vista, Calif. The plants are approximately one year old, grown one-gallon pots.

FIG. 2 illustrates a comparison of an inflorescence from the new variety ‘ALTBloom’ on the left and an inflorescences of the comparator ‘Peter Pan’ on the right. Inflorescences were harvested from plants grown under the same conditions, at approximately 1 year old.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used.
