The deep pink, very double flowers of 'POULesta' are round to irregularly rounded when viewed from above. When viewed from the side, the upper part of the fully opened flower is flattened convex to convex and the lower part is flattened convex. The flower centre is infolded to normal. Spots on the inner and outer sides at the base of the petals are medium in size. The petal margins have medium reflexing and weak undulation.

The filament of the outer stamen is yellow and the style is long, white with no hairs on the upper half. The stigma is positioned above the anthers. The receptacle is small to medium in size, has no hairs and is pitcher-shaped. The fragrance is absent or very weak. Resistance to mildew is moderate.

Origin & Breeding History: 'POULesta' arose from a mutation in the variety, 'POULprima', in the breeders' greenhouses in Fredensborg, Denmark in 1996. First selections were made in the spring of 1996 and propagated for further evaluation.

Tests & Trials: Tests and trials for 'POULesta' were conducted at Aldershot Greenhouses Ltd., Burlington, Ontario. The trials consisted of six 11.5 cm pots per variety, with four rooted cuttings per pot, originating from single node cuttings. Propagation was performed in high pressure fog. After moving to the production area, the plants were pinched after four weeks and again at eight weeks. The plant were grown by the sub-irrigation method, with a daytime and night time temperature of 22-24 C and HID lighting during the night. At the time of examination the plants were 12 to 14 weeks old.
