Smallest longifolia?

[Jure]

Recently I have find a population of very small D. anglica (D. longifolia), ~100 m2.

There are hundreds of adult plants, flowering, leaves lamina mostly smaller than 1 cm. Anybody knows for simmilar population?

Hi,

the reason why this plant is so small, is because it has not enough moisture in the soil. It prefers to grow in conditions where the water is on the soil level or above it. Best if there is sphagnum moss surrounding. It would probably change much if given different conditions.

I had an occasion to see something similar. When there was a population growing on water edge was normal size, but I also found a population on peat, where it had only humid conditions. The difference in their size was clearly visible.

I also had such situation once in my cultivation. I made a new pot for D. anglica and took some plants from Sphagnum moss and planted them on bare peat. The plants on peat shrunk a lot, although the same plants on Sphagnum grew typical way. Than I put Sphagnum in the new pot and those plants also changed. Their leafs elongated and now they look the same. It seems that the conditions have big influence on this species appearance.

Does it grow in a high altitude? I have heard some rumors about tiny alpine forms of D. anglica.

Not so high (750 m) as chill. 1/3 of the year is cold, the rest is winter.

D. anglica and D. intermedia naturally bonsia in slightly less than adequately wet soils.
