BACKGROUND OF THE NEW CULTIVAR

The present invention relates to a new and distinct cultivar of caladium plant, botanically known as Caladium×hortulanum, commercially referred to as a fancy leaf-type caladium, and hereinafter referred to by the name ‘Fiesta’.

Caladiums (also referred to as Caladium plants) are ornamental aroids frequently used as pot and landscape plants for their colorful foliage and ease of growing. The objective of the Inventors' breeding program is to create new Caladium cultivars that have compact growth habit, numerous leaves, attractive foliage, and exceptional container and landscape performance.

The new Caladium cultivar ‘Fiesta’ originated from a cross between ‘Florida Cardinal’ (commercial cultivar, not patented) and ‘Florida Sweetheart’ (U.S. Plant Pat. No. 8,526) that was made in Bradenton, Fla., in spring 2003. The new Caladium cultivar ‘Fiesta’ was discovered and selected by the inventors as a single plant in Wimauma, Fla. in 2005. The Caladium cultivar ‘Fiesta’ has been found to retain its distinctive characteristics through at least nine generations of successive asexual propagations via tuber divisions since 2004.

Plant Breeder's Rights for this cultivar have not been applied for. ‘Fiesta’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The new Caladium cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, water status, fertilizer rate and type, without, however, any variance in genotype.

The following are the most outstanding and distinguishing characteristics of this new Caladium cultivar when grown under (normal or standard) horticultural practices in Wimauma, Fla. The combination of these characteristics distinguishes ‘Fiesta’ as a new and distinct cultivar of Caladium:

• • 1. Compact, symmetrical, outwardly arching and rounded plant form;
  • 2. Mounding, dense and bushy growth habit;
  • 3. Multiple heart-shaped leaves that have a white center, red-purple mid veins, numerous greyed-purple primary veins, red purple bleeding along mid and primary veins, and netted green secondary veins throughout the leaf surface; and
  • 4. Attractive plants in containers or sunny or shady landscapes.

The new cultivar ‘Fiesta’ differs from its female parent, ‘Florida Cardinal’, in the following characteristics:

• • 1. Plants of the new cultivar are approximately 20% to 40% shorter than the plants of ‘Florida Cardinal’;
  • 2. The center area of leaves of the new cultivar is white with red-purple mid and primary veins whereas the center area of leaves of ‘Florida Cardinal’ is dark red;
  • 3. Leaves of the new cultivar have narrower green margins whereas leaves of ‘Florida Cardinal’ have wider medium-green margin (up to 3 cm wide);
  • 4. Petioles of mature leaves of the new cultivar are greyed-orange while petioles of mature leaves of ‘Florida Cardinal’ are greyed-red.

The new cultivar ‘Fiesta’ differs from its male parent, ‘Florida Sweetheart’ (U.S. Plant Pat. No. 8,526), in the following characteristics:

• • 1. Leaves of the new cultivar are of the fancy type, heart-shaped, with two large lobes. Whereas leaves of ‘Florida Sweetheart’ are of the lance type, elongated with a greater leaf length-to-width ratio and small to unobvious lobes;
  • 2. Leaves of the new cultivar are larger and wider than leaves of ‘Florida Sweetheart’;
  • 3. The center of leaves of the new cultivar is white and red, whereas the center of leaves of ‘Florida Sweetheart’ is rose;
  • 4. Leaves of the new cultivar are almost flat with thin green margins, while leaves of ‘Florida Sweetheart’ is undulate with wider margin;
  • 5. The mid and primary veins on leaves of the new cultivar have red-purple bleeding around the veins, whereas the veins on ‘Florida Sweetheart’ leaves have no surrounding bleeding coloration.

The new Caladium cultivar ‘Fiesta’ can also be compared to the Caladium cultivar ‘Florida Fantasy’, an unpatented commercial cultivar. In side-by-side comparisons of pot-grown plants conducted in Wimauma, Fla., plants of the new Caladium cultivar differed from plants of ‘Florida Fantasy’ caladium in the following characteristics:

• • 1. Plants of the new cultivar ‘Fiesta’ were about 10% to 20% shorter with a more compact growth habit than plants of ‘Florida Fantasy’;
  • 2. Leaves of the new cultivar ‘Fiesta’ have broader red purple bleeding coloration by the mid and primary veins whereas leaves of ‘Florida Fantasy’ have very limited bleeding coloring by the mid and primary veins;
  • 3. Leaf veins of the new cultivar ‘Fiesta’ have lighter red coloring whereas the leaf veins of ‘Florida Fantasy’ are darker red;
  • 4. Tubers of the new cultivar can sprout in about 7 to 13 days earlier than tubers of ‘Florida Fantasy’.

The new Caladium cultivar ‘Fiesta’ can also be compared to the Caladium cultivar ‘White Queen’, an unpatented, old commercial cultivar. In side-by-side comparisons of pot-grown plants conducted in Wimauma, Fla., plants of the new Caladium cultivar differed from plants of ‘White Queen’ caladium in the following characteristics:

• • 1. Plants of the new cultivar ‘Fiesta’ were about 30% to 40% shorter with a more compact growth habit than plants of ‘White Queen’;
  • 2. Plants of the new cultivar ‘Fiesta’ forced from tubers in containers produce approximately 1 to 2-fold more leaves than plants of ‘White Queen’;
  • 3. The background color of leaves of the new cultivar is whiter and more attractive than the background color of leaves of ‘White Queen’. Leaves of ‘White Queen’ are tinted with much more green;
  • 4. Pot-grown plants of the new cultivar are of higher plant quality than the pot-grown plants of ‘White Queen’;
  • 5. Tubers of the new cultivar can sprout in about 7 to 12 days earlier than tubers of ‘White Queen’, and tubers of the new cultivar can produce finished pot plants earlier than tubers of ‘White Queen’.

The new Caladium cultivar ‘Fiesta’ can also be compared to the Caladium cultivar ‘UF-48-5’, a patented cultivar (U.S. Plant Pat. No. 24,327). In side-by-side comparisons conducted in Wimauma, Fla., plants of the new Caladium cultivar differed from plants of ‘UF-48-5’ caladium in the following characteristics:

• • 1. Plants of the new cultivar ‘Fiesta’ were about 20% to 30% shorter with a dwarf growth habit than plants of ‘UF-48-5’ caladium;
  • 2. Leaves of the new cultivar ‘Fiesta’ have deeper red mid and primary veins while leaves of ‘UF-48-5’ caladium have lighter red to pink mid and primary veins;
  • 3. Leaves of the new cultivar ‘Fiesta’ have more restricted color bleeding by mid and primary veins than leaves of ‘UF-48-5’ caladium;
  • 4. Leaves of the new cultivar ‘Fiesta’ do not have white blotches between primary veins whereas leaves of ‘UF-48-5’ have white blotches between primary veins.

Comparison with Known Cultivars

The new cultivar ‘Fiesta’ was evaluated for tuber production at the Gulf Coast Research and Education Center in Wimauma, Fla. in 2007 and 2009. The soil was EauGallie fine sand with about 1% organic matter and a pH value between 6.2 and 7.4. Caladium plants were grown in the field using a plastic-mulched raised-bed system. For the 2007 evaluation, ground beds (81 cm wide, 20 cm high) were fumigated on 3 April with a mixture of 67% methyl bromide and 33% chloropicrin (by volume) at the rate of 196 kg·ha⁻¹. Caladium seed pieces (tuber pieces, approximately 2.5×2.5×2.5 cm) were planted manually on 26 April with approximately 25.4 cm between-row spacing and approximately 15.2 cm in-row spacing. Drip tapes were buried under the plastic mulch and delivered approximately 6 mm of water to the bed per day. Fertigation (through the drip irrigation system) began when young caladium plants emerged from the soil, supplying soluble fertilizer (6N-0.8P-3.9K) at the rate of approximately 1.9 kg of nitrogen·ha⁻¹·day⁻¹ and a total 290 kg of nitrogen·ha⁻¹ per growing season. Tubers (new crop) were dug, washed, and dried in early January 2008. Dried tubers from each experimental field plot were weighed, graded, and counted in late January 2008. Tuber grading was by the tuber maximum diameter: Super Mammoth (greater than 11.4 cm), Mammoth (8.9 to 11.4 cm), Jumbo (6.4 to 8.9 cm), No.1 (3.8 to 6.4 cm), and No. 2 (2.5 to 3.8 cm). Tuber grades and counts were converted into a Production Index (PI) to show the relative economic value of the harvested tubers per field plot: PI=8n(Supper Mammoth)+6n(Mammoth)+4n(Jumbo)+2n(No.1)+1n(No.2), where n=number of tubers in the grade. The relative values assigned to the five tuber grades in calculating PIs were based on the relative market prices provided by Florida caladium tuber producers.

For the 2009 evaluation, beds were fumigated on 27 February with a mixture of 50% methyl bromide and 50% chloropicrin (by volume) at the rate of 196 kg·ha⁻¹. Caladium seed pieces were planted on 9 Apr. 2009 at approximately 15-cm spacing between rows and in rows. The irrigation and fertigation system was the same as the one used in 2007, but one teaspoon (approximately seven grams) of OSMOCOTE® controlled-release fertilizer (15N-2.6P-10K, 5-6 months) was applied to each plant on 21 July. Tubers were dug from 30 Nov. to 2 Dec. 2009, followed by washing, drying, weighing, grading, and counting as was done in 2007.

Field plots were arranged each season in three randomized complete blocks, and each plot (1.2 m²) was planted with 30 caladium seed pieces. Two commercial cultivars, ‘Florida Fantasy’ and ‘White Queen’, were included as controls in each block. Analyses of variance were conducted using the PROC GLM procedure in SAS (SAS Institute, Cary, N.C.) to compare the tuber yields of ‘Fiesta’ to that of ‘Florida Fantasy’ and ‘White Queen’.

Table 1 shows the tuber weight, marketable tubers, production index, and grade distribution of the new cultivar ‘Fiesta’ grown in Wimauma, Fla. in 2007 and 2009, as compared to those of ‘Florida Fantasy’ and ‘White Queen’. Values presented for each year are means of three plots in three randomized complete blocks.

As shown in Table 2, Plants of the new cultivar ‘Fiesta’ and ‘Florida Fantasy’ had similar numbers of leaves per plant (22.0 and 21.5). Their leaves were similar in width (17.6 and 18.0 cm), but had different lengths (22.4 cm and 28.7 cm, respectively). Compared to plants of ‘White Queen’, plants of ‘Fiesta’ had 63% more leaves and leaves were 6.5 cm shorter.

Table 3 shows the landscape performance of the new cultivar ‘Fiesta’ with ‘Florida Fantasy’ and ‘White Queen’ when planted in ground beds in full sun in 2007 and 2009. Values presented are means of three replications in each year.

Landscape performance was evaluated on the same plots used for evaluating tuber production. A scale of 1 to 5 was used with 1 being very poor (few leaves and lack of vigor), and 5 being excellent (full plants, numerous leaves, and bright color display). Leaf sun tolerance was evaluated on a scale of 1 to 5, with 1 being very susceptible to sunburn (leaves having numerous sun-dainaged areas or holes) and 5 being resistant to sunburn (no visible sun-damaged areas). Three to four evaluations were conducted in each growing season for plant performance and sunburn tolerance. Evaluations were done in July, August, and September 2007, and August, September, and October in 2009.

As shown in Table 4, plants of ‘Fiesta’ showed excellent sunburn tolerances in both 2007 and 2009 growing seasons, with sunburn tolerance ratings between 4.0 and 4.6 in all six evaluations. Plants of ‘Florida Fantasy’ and ‘White Queen’ received similar sunburn tolerance ratings (3.8 to 4.5 for ‘Florida Fantasy’ and 3.5 to 5.0 for ‘White Queen’.

The suitability of ‘Fiesta’ for pot plant production was evaluated by forcing tubers in 11.4-cm containers in spring 2008. Intact No. 1-sized tubers (>3.8 cm and <6.4 cm in diameter) were planted in a peat/vermiculite mix (VerGro Container Mix A, Verlite, Tampa, Fla.) on 17 Apr. 2008. The study was conducted in a greenhouse with 45% light exclusion. Average daily temperatures in the greenhouse ranged from a low of 16° C. at night to 29° C. during the day during the experiment. Potted plants were arranged on metal benches in the greenhouse in a randomized complete block design with eight replications. Plant height, plant width, number of leaves, and foliar characteristics were recorded on 12 Jun. 2008, 8 weeks after planting. Quality of the potted Caladium plants was rated on a scale of 1 to 5, 1=very poor, few leaves, totally unacceptable as potted plants, and 5=very attractive, with many bright, colorful leaves, a full plant, a symmetrical shape, and an appropriate height.

Table 5 shows a comparison of number of days to sprout, plant height, plant width, leaf number, leaf length, leaf width, and quality rating of ‘Fiesta’ with ‘Florida Fantasy’ and ‘White Queen’ when intact and de-eyed tubers were forced in containers in spring 2008.

As shown in Table 5, the new cultivar ‘Fiesta’ was quick to sprout regardless of tuber treatments. Intact and de-eyed tubers sprouted 22 and 23 days after planting, respectively, 7 to 13 days earlier than ‘Florida Fantasy’ and ‘White Queen’ (Table 5).

Plants of ‘Fiesta’ had an average height of 20.3 cm (intact tubers) and 18.6 cm (de-eyed tubers), similar to the plant height of ‘Florida Fantasy’ (22.9 cm for intact tubers and 21.5 cm for de-eyed tubers), but significantly shorter than the height of ‘White Queen’ (32.0 cm for intact tubers and 29.1 cm for de-eyed tubers) (Table 5). Plants of ‘Fiesta’ had an average of 14.9 (for intact tubers) or 32.8 (de-eyed tubers) leaves per plant, 84% and 188% more than ‘White Queen’ plants had (Table 5). Leaves of ‘Fiesta’ and ‘White Queen’ plants from intact tubers were similar in length and width, whereas leaves of ‘Fiesta’ plants from de-eyed tubers were shorter and narrower than those of ‘White Queen’ plants from de-eyed tubers. Plants of ‘Fiesta’ received a quality rating of 2.4 (for intact tubers) and 4.0 (for de-eyed tubers), respectively, which were significantly higher than the quality rating of ‘White Queen’ plants.

Plants of ‘Fiesta’ from intact tubers had similar leaf numbers (14.9 and 14.1) and leaf lengths (27.1 and 24.8 cm) with plants of ‘Florida Fantasy’, but a greater leaf width and a lower quality rating than plants of ‘Florida Fantasy’. However, plants of ‘Fiesta’ from de-eyed tubers had 59% more leaves, and leaves were 2.7 cm shorter and appeared to be 1.7 cm narrower than those leaves of ‘Florida Fantasy’ from de-eyed tubers. Plant quality ratings of ‘Fiesta’ and ‘Florida Fantasy’ were comparable (4.0 and 3.7) when their tubers were de-eyed before planting.
