Alpine houses allow alpine plants to be grown in places with significantly different conditions from those they would experience in their native habitats. In the wild, alpines spend the winter dormant, dry and protected from the desiccating effect of cold winds by a blanket of snow.
Spring in alpine climates arrives rapidly, with melting snow providing moisture for growth. A short growing season means that plants have to grow quickly, taking advantage of the brief period of moisture and intense light. Seasonal changes in alpine climates are abrupt.
Horticultural alpines also benefit from the protection of an alpine house. The rainfall in their natural environment may vary significantly from the conditions in Britain. The protection from frost afforded by a house further extends the range of plants that can be grown and high temperatures can be avoided by shading, ventilation and other devices.
Britain's weather conditions are considerably different, being defined by fluctuating temperatures and humidity. In an alpine house, shading, air movement and additional light can all be provided. Most importantly, where plants are grown in a protected environment, the amount of water they receive can be controlled, giving them the cultural conditions they need to thrive.
I hope that makes things a little clearer Toby.
We don't have an Alpine House yet. I say YET as our garden space is at a premium at the moment, but Kathy is now hinting at
ME constructing a smaller structure in a 'little' unused corner of the rear garden.
I build her an obelisk then she goes wild with enthusiasm, having great plans for my next woodworking task. Ho hum. I suppose that's what comes of watching too many episodes of
The New Yankee Workshop with Norm Abrams. I'm really flattered that she believes I have the skill and confidence to tackle such a project.
We have just recently got into growing Alpine plants, and Eric (Palustris on the Forum) has been a great help and inspiration to us. Telling us suitable plants for our location, and ones to avoid because of their invasiveness. Thanks again Eric for all your help, it's much appreciated.
So, if I get my arm twisted by Kathy I may yet be embarking on an Alpine House project.
As they say, watch this space... (or rather, watch the space in the
Garden Buildings section of the Forum.)
Laurie.
