Flowers in Containers

In May I planted Nasturtium (Tropaeolum), Brachikome, decorative Sunflowers, Asters, Nasturtium, Begonia and Impatiens in garden pots, tubs and urns. But plants stopped growing and acclimatized for about 2 weeks. They grew very slowly, possibly due to cold nights. I think so, but perhaps the reason is different.

I usually prepare the soil before planting seedlings, mix the soil with sand, compost and manure, sometimes add last year's leaves. I often cultivate seedlings and suggested that they would develop well.

Pelargonium and Impatiens

Nasturtium

When forecasted on cold nights, I placed the most delicate flowers in the greenhouse. Then I had to return to the city, I covered them with a special cloth, and begonia and fuchsia were not affected by the cold.

Impatiens Balsamina

Fuchsia

Impatiens walleriana

It's June the days and nights are warm, Asters Sunflowers Impatiens Gladioli  Pelargonium grow in tubs, tolerate night temperatures well. Nasturtuim and Brachycome began to bloom in hanging pots.

Sunflower (Helianthus)

I noticed that the smaller the container is, the soil dries out faster and plants need to be watered more often.

It's June, the first month of summer. Here we call it "top of the year" or Midsummer. Plants became stronger and bloom more beautifully.

Brachikome

I wish you warm and sunny weather.

Fritillaria meleagris

I learned that the name of the plant comes from the Latin word fritillus - a chessboard; it is given due to the variegated coloring of some varieties of flower resembling a chessboard. According to another version, the name comes from the Latin name for a cup or vessel for playing dice and is associated with the shape of the flower.

 The wiki said the plant has many common names in different countries, they are: snake's head, chess flower, frog-cup, guinea flower, leper lily, Lazarus bell, chequered lily or daffodil, drooping tulip, etc.

What do you call this plant?

Over time, eyes get tired of the brightness and pretentiousness of many garden flowers. And fritillaria has a calm color of bell-shaped flowers: white, brown, yellow, green, purple, besides it is remarkably complemented by the elegance of the whole plant. I grow two species of Fritillaria: meleagris (chequered) and involucrata (white specie)

Under the ground fritillaria has a bulb where nutrients accumulate. They support plants during dormancy and at the beginning of the growing season. The shape of the bulbs is very diverse, most often elliptical. 

I love to wait for the start of plant growth that begins in spring with an abundance of moisture in the soil. In a short time, the plant forms a stem, leaves, blooms, forms a new bulb. In June it freezes until the next season.
At this time the bulbs can be dug, transplanted, stored, forwarded. In late summer or early fall fritillaria begins underground stem growth and root formation.
What is your experience in Fritillaria growth?

Tradescantia Virginiana

Tradescantia virginiana, the Virginia spiderwort - I'm sure most of gardeners are familiar with this plant. Many years I thought that Tradescantia is an indoor pretty flower. Once I was surprised to see Tradescantia virginiana or Virginia spiderwort growing outdoors. So I bought it for my garden and do not regret.

Tradescantia virginiana is a perennial plant up to 0.4 m. It is hardy for my zone 5a. It blooms from June to October, and the seeds ripen from August to October. It spreads itself, and when it is planted, it will take up more space.

The flowers are purple, reddish, densely blue, blue or white, in simple inflorescence. The flower has three petals, opens only for one day, but clusters of buds in each inflorescence guarantee a long, continuous flowering.

Do you have Virginia spiderwort in your garden? What other flowers do you think suit it?
