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 !
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 !
When you go below 300 foot candles of light (my definitions of a dark garden) there is so little light energy striking any leaf that plants basically use up their stored calories then wither away. It happens because the plant cant produce the necessary sugar, nor has enough in storage, to run its core metabolism. It gets weak really quickly.
Insects and/or disease may even strike before they have used up their stored food. Same reason – a weakened metabolism. So it is quite important to take into consideration their susceptibility to pests or you simply will be fighting the environment. Example : Some shade tolerant Azalea would possibly work – but they get spider mites quickly if weak – and look terrible even quicker ! – and – you will be spraying them forever!
Choosing a plant that is both super low light tolerant and not prone to insects and diseases is the best way we have found to have a successful shady garden. Here are Plant Specialists suggestions – based on 50 years of gardening in all different conditions.
