Now that's shady !
The impossible dream
If you cant keep anything alive (let alone grow) in a dark shady garden then listen up – we have a few choices for you that we have tried in our gardens for many years, and are very happy with the results. They hold up well without much effort - certainly proven winners !
A spectacular shady garden
What does shade mean
Everyone you talk to clearly understands the meaning of shade. Most also have a hard time defining it in terms of plant needs. We draw the line in the sand at 300 foot candles and below - and define shade that way.
Foot candles are a measurement of the number of photons (energy particle) from the sun that strike a leaf. These are responsible for activating the chlorophyll and starting the photosynthesis cycle - the chain of reactions that eventually produces sugar.
A foot candle light meter
When you go below 300 foot candles of light (my definition of a dark garden) there is so little light energy striking any leaf that plants produce too few sugar molecules. The simply use up their stored calories ( sugar and starch) then wither away.
Light rays (photons!) striking a leaf
When a plant has a sugar deficit it gets weak really quickly. Insects and/or a disease may even strike before they have finished using up their stored food. Simple reason – a weakened metabolism.
The hurdle
Having a successful shady garden is all about overcoming 2 things – tolerance to low foot candles, and low susceptibility to pests. There are not a huge amount of plant choices that have both conditions - but I bet more than you thought!
Perhaps the only other consideration is that you will have to give up the day dream of that English cottage look – and instead embrace the beauty and simplicity of these hardy plants. But don't despair ! – there are plenty that have colorful foliage and flowers to brighten up the day !
It is quite important to take into consideration their susceptibility to pests. Otherwise you will be fighting the natural environment. Example : Some shade tolerant Azalea would possibly work in a 300 fc garden - but they get spider mites quickly - and look terrible even quicker ! And god forbid - you only other choice would be spraying them forever!
