Sow rare flower seeds (late winter - early spring)
SEEDING SEEDS OF RARE FLOWERS - THE END OF WINTER BEGINS OF SPRING
I want to talk about the cultivation of crops whose seeds are sown optimally in late winter and early spring. And give advice to beginner growers from their many years of experience.
Bellflowers
Most common species grow well both when sowing with short stratification, and in the winter.
According to the requirements for growing conditions, their relatives are similar - colniki. Among them there are fairly unpretentious species, there are more capricious, but the bulk prefers soil rich in calcium. I sowed several species of stalk in winter, including the capricious crested one (it was treated with gibberellin seeds): some of the species sprouted “in the forest”, some gave single shoots, but the seedlings turned out to be quite stable, although they developed slowly at first.
Adrayanthus can rise in warmth, but more reliable and more productive is winter sowing or combined stratification. It is advisable to add limestone nibs (sold in pet stores) to the substrate for sowing and picking, to make good drainage, to prevent jamming, including in the area of the root neck.
Meconopsis
Sowing time mekonopsis literalaceous (Meconopsis betonicifolia) and similar species requirements (cambrian meconopsis, large meconopsis and others) - spring. It should be borne in mind that they are sensitive to elevated temperature and dry air. I liked to sow and grow them in a glazed, but insulated loggia, where the temperature is not much higher than on the street. Therefore, I usually do not rush to sow them until the end of March or the beginning of April. Sow over peat based substrate.
Their seeds usually germinate well (if stored for a year or even two), but there are also failures with purchased ones. Mekonopsis, more likely, has a fibrous root system, so seedlings tolerate picking and transplanting quite well. The main thing is to prevent their overheating and drying out (as well as waterlogging). Young plants can be kept in pots, or they can be planted in a shaded place for growing in a school - there they develop faster.
Penstemons
Most species require multi-stage stratification, and seeds are best sown before winter (seedlings can also appear after the second or even third winter), although some can germinate in heat with a little preliminary cooling.
The exception is shrubby (Pennellianthus frutescens), it germinates well in the heat. Presowing seed treatment with gibberellin can increase germination.
The main problem is to preserve seedlings and young plants that do not like sharp fluctuations in temperature and humidity. They are very photophilous, with a lack of lighting, they are very elongated, they prefer coolness. They grow fast, so it’s better not to rush into sowing or to provide them with good illumination and coolness.

The formation of buds in cambria does not depend on the season and occurs 9-10 months after the previous flowering. The orchid does not have a pronounced rest period, but between flowering it must rest for some time. During this period, I transplant and propagate it, separating the pseudobulbs. I add charcoal to the pine bark substrate. I protect the plant from direct sunlight. I water it with warm soft water, without moisture stagnation. In the summer I take it out into the open air (tolerates a drop in temperature to +5 degrees). In gratitude for leaving Cambria gives "dancing" colorful flowers.
