Organic Flower Gardening with a container planting concept is a supper idea for a small garden.
If you are looking for some showy hardy types of flowers plants that could produced dark-green leaves with brown hearts; you can consider these generous four leaf clovers, Oxalis deppei (pictures below).
Generally there are annual, perennial, and bulbous; three types of Oxalis plants. These sweet flower plants are also known as Iron Cross. You can grow them in containers; pots; baskets or in the open ground.
You can start sowing the seeds from late winter to early spring; either indoor or outdoor. Insert the mini bulbs about 10cm in the soil; and 10cm apart. However, if you are short of space; just make sure they have sufficient breathing space from each other; they are able to grow pretty well with minimum space.
These low growing hardy window box flowers require the heat from the sun to expand. They love plenty of water and good drainage 3-inch containers during the growth.
Covering them from the chilling wind in the seed germinating period is necessary; if you are setting your containers outdoor.
Last year, I have grown these four leaf clover plants in 2 separate locations.
I discovered that, those grown in the long green window flower box with ordinary potting soil; next to the South garden hedge were not as cheerful as those in an old basket of sandy loam; which had started first in the greenhouse.
Through my observation, although these flower plants could survived in a half shady place; but they were not so strong as those in the basket. It may be due to too much rain fall during early spring; so very soon their leaves turned into red-yellow and eventually brown; and they had less flowers.
Those plants in the basket were gaining abundance of direct sunlight everyday at the North edge of the garden. Therefore, they bloomed continuously from mid-May to August; and received less insects disturbance.
After an enjoyment from the long session of charming and sweet pink blooms; and the good foliages; you may collect the seeds before the cold arrives.
These flowering bulbous plants can be propagated by seed, offsets, and division of roots.
