PLANT FOR SALE  2020
NOVELTIES AND PLANT TREASURES FROM THE TAMBERG GARDEN

In 2020 we shall not introduce any new daylily and iris varieties. At the same time a number of old varieties will disappear from our list, because we can no longer afford to keep them in stock due to problems with space and workload. However, quite a number of new varieties have been selected, and their stock size will be sufficient for introduction in 2021.

Only a limited number of plants of our newer varieties are available for sale. We wish to make these plants available for our customers before we might possibly be forced to retire.

In 2019 our beardless irises and some daylilies have again suffered a lot as the result of the hottest and driest summer since the beginning of weather recording. At the same time our consumption of water for irrigation reached record level, too. We hope, that our plants will survive the coming winter in good condition.

In 2020 our plants will be dispatched exclusively for spring planting during the first two weeks in April. Our plants are bare rooted, and therefore we must insist on precise rules in respect to ordering time and shipping period in order to get the plants healthy and in time to you. Please, have in mind, that the easter holidays fall into our shipping period. In order to be considered orders must reach us by the 31st of March 2020 at the latest.  Please, take note of our terms of delivery.

IRIS      (directly to daylily offer)

Schneesturme

Schneesturmh

Iris tetrasibtosa SCHNEESTURM (Tamberg 2019)

All our attempts to produce a white 3/1-Tetrasibtosa hybrid had so far ended in blue, in spite of two white parents. The new variety SCHNEESTURM comes from a single spontaneous seed, harvested from a white, diploid Sibtosa hybrid treated with colchicine. This variety is very vigorous. Flower spikes are up to 130 cm tall and produce up to nine buds on two side branches and a terminal. According to the type of hybrid the ferility is very low.

The plant forms only two buds per spike, but it compensates by the number of spikes. GROSSER WEIN is fertlle and flowers shortly before the peak bloom period of the Sibiricas.

The strong flower spikes can have two side branches, but with 75 cm height they are bit short relative to the size of flowers.
