This is one of the most floriferous tetraploids
we know of. The flower spikes often have a double side branching. Falls
and standards are wide and ruffled. Further more, the bright wine red
colour has a better garden effect than the dark purple colours of other
Sibiricas in this colour class. Weinkönigin is vigorous, healthy
and fertile in both directions. The flower spikes are about 85 cm tall

With this cultivar the yellow colour is for
the first time shown to a significant extent in a Sibirica/Setosa hybrid.
This was achieved by using the yellow Sibirica Tom Schaefer as the seed
parent. Northern yellow is vigorous, hardy and floriferous, but sterile.
It is about 70 cm high . . . Sold out for 2012
We got this stately plant by back-crossing
a tetraploid Iris laevigata to a tetraploid versilaev hybrid. Its flowers
are significantly larger than flowers of normal Tetra-Versilaev hybrids
and are produced on taller, branched stems. This is the first introduction
of a hybrid with a 3/4 Iris laevigata and a 1/4 Iris versicolor parentage.
Libellentanz can be planted near or even in water and it is less vigorous
when planted on a dry garden bed. The flower spikes are about 75 cm high

From the BIS seed exchange we got seeds of
tetraploid Iris versicolor x ensata hybrids sent by the Canadian hybridizer
Toni Huber. The group of seedlings was not very exciting, but it contained
a single plant which stood out by enormous vigour and also was very floriferous.
Its flowers are nearly double the size of those of its siblings. The flower
spikes show a double branching and are about 90 cm tall. Occasionally they
need a staking. Like its relative Libellentanz
Libellenflug needs a wet planting site for best performance.

This is a plant for use in landscape gardening.
It was produced by crossing a tetraploid Sibirica of near-species appearance
with one of our best Tetra-Sibtosa hybrids. Like both of its parents it
has lavender-pink flowers with lighter standards. The flower spikes grow
to a height of 150 cm, have a twofold branching and produce seven flowers.
The stems and the narrow leaves are strictly upright and in this way they
produce a columnar appearance of the clump. Lavender Landscape is one of
our most "garden-effective" cultivars. In 2011 we noticed a significant
spontaneous seed setting in spite of its 3/1 genetic makeup . . .

A cross between the cultivars Tom Schaefer
and Sunfisher resulted in this yellow Sibirica of delicate
growth habit. It can produce one, sometimes two side branches of the the
flower stems and shows a much better, sun-resistant yellow than earlier cultivars
like Butter and Sugar or Gelbe Möwe. The flower spikes grow to about
65 cm. Sibirisches Gold is fertile in both directions . . . . . . . .

Sibcal hybrids are produced by back-crossing Tetra-Calsibes to Tetra-Sino- Sibiricas. RAY JEFFS, named in honour of a deceased English friend and iris lover, is the most beautiful in a long series of Sibcal hybrids we have produced. Whereas nearly all the others did not become named varieties due to their lack of longevity, Ray Jeffs is not only beautiful, but vigorous and long-living.

Worldwide the first named variety from the new hybrid group "Versitosa hybrids". They are produced by crossing Iris versicolor with tetraploid Iris setosa. Since I. versicolor is considered to be a tetraploid natural hybrid between I. virginica and I. setosa, Versitosa hybrids can be seen as plants with 1/4 Virginica- und 3/4 Setosa-blood. They are very vigorous and floriferous when planted at a humid place. Stems are about 80 cm tall and can develop three side branches and 11 buds.

in contrast to earlier Tetra-Sibtosas, has wide and strongly ruffled falls
as well as a strong colouration. The flower stems are about 75 cm high and

Of all the wine red Siberian irises we have
flowered, GROSSER WEIN is the one with
the largest flowers. Of course, large flowers are not
always beautiful, too, but in this case large flowers
with wide and elegantly ruffled falls are combined with tall
and upright stems of 90 cm height. Only two flowers are
formed per stem, but this is compensated by the high number of
stems formed by a clump. The variety is fertile and flowers during
the earlier part of the Siberian main flowering period

with a tetraploid Iris typhifolia, that was available to us
