Blossoming seal of Solomon under the gardens shade

When planning a garden, a gardener always considers which shade-tolerant plants to plant under the trees. Near trunk circles of fruit trees are usually mulched to reduce moisture evaporation from the soil. The rest of the earth under the trees’ crown remains as a blank brown spot. This is neither aesthetic nor practical.

1. It’s not aesthetic because a garden that has no plants under the trees, doesn’t convey a very cheerful mood.

2. It’s not practical to leave the soil empty under the trees’ crowns because it gets colonized by weeds, which are brought by the wind little by little. That’s why additional work is needed to rid of the weeds in the garden. Besides, under the influence of the rain or wind, the soil becomes denser and the access of air to the tree roots is decreased.

That’s why it would be advantageous to plant such shade-tolerant plants which would bloom in the shadow and brighten up the garden when covering the soil with their unusual leaves. Some plants are not just shade-tolerant, but consume only a small amount of water, and yet there are others who love well-moistened soils.
