Tulipa tarda is native to the rocky subalpine meadows of Central Asia (steppes of Eastern Turkestan, other sources state that it is an endemic species of Kazakhstan). Bulbs of this species have a thin yellow skin, the leaves are narrow, in a rosette of three to seven grow from underground parts of the stems. The petals are yellow with white tips, outside on a green background purple colored. Several flowers appear on branching stems. Tulipa tarda flowers in the second half of April and early May. The species grows to a height of 15 cm.
The sowing of seeds is as easy as the cultivation of the tulip. Last year I sowed seeds in early autumn into the soil, scattered several hundred seeds
on a half a square meter of land, and slightly earthed them up, and everything else I have left to nature. Although this was a long winter, the seeds germinated in large numbers during March, at the same time as the bulbs of the adult plants started to shoot. Surprisingly, the seedlings coped with the weather in April when the soil froze up at night and during the day due to increasing temperatures above zero again thawed, which lasted if I remember about 14 days to three weeks. When the weather got better a little bit, the "lawn" of sprouted seeds became thicker and wilted at the end of May.
Now I have gathered this year´s seed crop and I have put it up for sale: http://www.sedmdesatosmicka.cz/nabidka-rostlin/semena-seeds/
I grow Iris pseudacorus a second year. The first winter I had a plant in a pot at home, because there was no time to deal where to place the plant in the garden in late autumn. Sometimes I watered rhizomes to soil does not dry out completely. I planted rhizomes into the soil last spring. The plant created about 1 m high leaves but not flowered.
Iris pseudacorus is native to Europe and the British Isles, Western Asia, North Africa, and the Mediterranean region. Although I. pseudacorus occurs naturally in wetland habitats, growing in the garden without specific requirements for wet environments. Owing to an abundant rainfall in this year I do not water the plant.
Stiff leaves remained green through the winter and dried up in late winter and spring. New leaves grew to 1.5m and develop flower stalks usually with three flowers that were beginning to bloom in mid-May.
