Variety Description

Varieties used for comparison: 'Fip 469' (Rocky Mountain Lavender Pink 2004) and 'Fiseyely' (Calypso)

Summary: 'Fisrolav' is a larger plant than 'Fiseyely'. 'Fisrolav' has longer petioles and shorter pedicels than 'Fip 469'. The flowers of 'Fisrolav' have fewer petals than those of the reference varieties. 'Fisrolav' has a smaller inflorescence diameter and smaller flower diameter than 'Fiseyely'. The upper petals of 'Fisrolav' have stripe markings which are moderate to strong in conspicuousness while those of 'Fiseyely' have stripe and spot markings which are very strong in conspicuousness.

Description:

'Fisrolav' is a zonal type pelargonium variety which has an upright to intermediate growth habit. The stem is green in colour, medium to thick and has dense pubescence. The leaf is a type 3 shape with an open to closed base and moderate to strong lobing. The crenate margins have medium deep incisions and weak to strong waviness. There is dense to very dense pubescence on the upper side of the leaf blade. The colour of the leaf blade is medium green with no variegation. The weakly to moderately conspicuous leaf zone on the upper side of the leaf blade is in a normal position and green in colour. The petiole has dense to very dense pubescence.

'Fisrolav' belongs to the pink/violet inflorescence colour group. The peduncle has dense to very dense pubescence and absent to very weak intensity of anthocyanin colouration. The flower buds are elliptic in shape. The florets are semi-double and dark blue pink in colour. There are stripe markings which are moderate to strong in conspicuousness on the upper petals and no markings on the lower and inner petals. The petals are overlapping and the width of the upper petals is medium. The petal margins are entire. The white zone at the base of the upper petal is large. The pedicel has dense to very dense pubescence and the colour in the middle third is medium red. The colour of the sepals is green with red at the base only.

Origin & Breeding History: 'Fisrolav' originated from a hybridization in 1998 between the female parent 'K96-0827-2', a hybrid seedling with light violet, semi-double flowers, dark green foliage with zonation, compact to moderate growth habit and late flowering, and the male parent 'K93-1030-1', a hybrid seedling with similar flower colour but, single flowers, dark green foliage with faint zonation and more vigorous growth habit. The hybridization and selection in 1999 was conducted in Moncarapacho, Portugal. Cuttings from the selected seedling were taken back to Hillscheid, Germany for further selection and trial cultivation in 1999. Final selection was based on the lavender pink flower colour in combination with vigorous growth habit.

Tests & Trials: Tests and trials for 'Fisrolav' were conducted in a greenhouse during the spring/summer of 2003 at Westcan Greenhouses, Ltd. in Langley, British Columbia. Trials consisted of 15 plants per variety grown from rooted cuttings which had been transplanted into 9 cm pots at week 13 and repotted into 20 cm pots at week 23. The pots were spaced 45cm apart, from the pot center. The plants were grown in a peat:perlite mix (60:40), fertilized with a constant feed of Plant Products 20-5-30 / Calcium and Magnesium, and shaded when light levels were above 5000 foot candles. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten plant measurements.
