Timophylla Yellow - A Trendy Summertime Flower For The Container Garden

, Admin

In recent years, among garden annuals, timophylla yellow has been considered one of the major fashionistas. Its radiant, saturated sunny yellow color even with the current variety of seasonal stars is considered rare rather than common. And when little daisies scatter like thousands of stars on a lace bush, it is impossible to take your eyes off this sight. It is not easy to look after Thymophylla, it always needs attention, but it is hard to imagine a brighter summer flower. © ho4kawa

Botanical description of thymophylla

From among garden lettuces, thymophylla is considered a new, fashionable and outlandish plant, although it has been used in landscape design quite a long time, since the early 20th century. The fashion for thymophylla came to us from Europe. The tendency to search for new, unexpected solutions and the fashion for the most luxuriant cultures has attracted attention to this plant. Only one of thirteen species of the genus Thymophylla is very popular today, the golden-yellow or narrow-bladed Thymophylla ( (Thymophylla tenuiloba). Thymophylla is a colorful plant native to Central America.

The name Timophylla is not very popular with us, as are the various nicknames of the plant. Previously, this annual was qualified as Hymenatherum, but this name is almost nowhere to be found in our country. Timophyllum is often confused with Dissodia, although they are independent genera in the family of the Compositae and differ somewhat in the type of shoots, greenness and inflorescences.

Thymophyllum is also often compared with Brachycoma and even called yellow-flowered Brachycoma, although the plants differ significantly in color palette and details of structure. The popular nickname, yellow daisy, is also popular.

Brassy and densely branched, timophylls form strikingly beautiful cushions. Thymophylls are only 30 cm high, though the plant often grows to less than 20 cm due to the drooping shoots. Thymophyllum shoots are very slender and seem unusually fragile, they do not droop themselves, but they are not stable enough and may spread out as a luxurious cushion, slightly drooping, along the edge of containers or if there is enough space.

The thin needle-like or filamentous lobes of deeply dissected leaves form, together with the twigs, a continuous openwork mass, as if the whole plant were a continuous lace of small leaves. The same color of greenery and shoots further enhances the feeling of an unprecedented curly plant. The shade of green in Timophyllia is unique: it is not only much darker than in the majority of common annuals, but also cool, emerald-blue-white-coniferous.

The flowering period of golden-yellow timophylla usually lasts from May to July, though with timely pruning and removal of fading flowers and correct care it can bloom literally till October. This is a small-flowered, but lushly flowering summer flower. On one bush thousands of basket-shaped inflorescences bloom.

In diameter inflorescences usually will not exceed 1 cm, but they are so bright in color and bloom in such quantity that this disadvantage is not noticeable. Timophylls golden-yellow, even in the best varieties, are always colored only in a bright, sunny golden tone. Typical baskets with a not very large center of small orange tubular flowers and narrow-lanceolate lingual flowers in a circle on the bush appear to be multi-beam stars or miniature suns.

Popular varieties of Timophylla golden-yellow

In addition to the basic plant, even more abundant varieties are increasingly available today. In recent years, the amazing variety "Stemschnuppe" has been particularly loved by garden centers. This is a thymophylla with an even brighter shade of yellow and a much thicker emerald-grayish green. It seems diminutive compared to the classic summerfly.

Possessing a brighter, more intense grassy green, the variety "Gold Carpet", which the seed producers recommend as a border summerfly, also deserves attention. Like the longer flowering Golden Dawn or the lemon-golden, larger and spreading Shooting Star with flowers from 1.5 cm in diameter.

Use of Timophylla in Ornamental Gardening

Timophylla are the golden queens of ampels. They are grown primarily in hanging baskets. Despite the fact that the plant can be introduced in complex ensembles, combined with other annuals, the full beauty of the plant will unfold in proud solitude.

Timophylla can be used as a border for large canopy and pot plants, as a filler between perennial potted plants or in flower boxes.

Timophylla in the garden is best placed where there is a sense of boredom or gloom - as a lively, illuminating, brightening accent. It as if softens large structures and planes, perfectly compensates massive wooden structures.

Timophylla golden yellow is a real star of balcony design. But it looks just as good on the terrace, in the pergola, on the veranda, in the rest areas in the garden. This is a typical potted summer plant. Very rarely the plant is planted in the ground because of its sensitivity to moisture and difficulties of care, but lately I've been experimenting with the use of Timophyllum as a border or groundcover, masking the voids in flower beds, which need regular watering.

Best partners for timophylla golden yellow: pelargoniums, calceolaria, chrysanthemum, lantana, geraniums, geichera, brachycoma.

Conditions needed by timophylls

Timophylla golden-yellow is one of the most light-loving summer plants. Regardless of whether the plant is grown as an ampelagic crop or in boxes and pots, timophylla should always be exposed to the brightest possible light.

This summer plant likes loose, weakly acidic, quality soil containing organic matter. For thymophylla suitable universal substrates for flowering crops.

If thymophylla is planted in soil, choose only sunny, draught-proof sites and neutral or slightly acidic, loose and nutritious loam.

Propose the plant in the open ground only in late May, when return frosts are over. Plants in containers can be taken out into the fresh air at the same time. In spite of their status of heat-loving plants, mature timophylls can continue flowering even when the temperature drops to 0 degrees.

Timophylls care

Timophylla golden-yellow is not the most capricious of summer plants, but it needs regular and careful care. Besides the traditional basic care any Timophylla will need measures to stimulate and support flowering.

Wetting for this shrub is carried out not too often, but abundantly. Timophylla quickly loses its decorativeness when the soil dries up, but it also does not like overwatering, dampness. The frequency of these procedures is established by checking how the substrate in the pots dries out. In summer, the plant needs daily, and even more frequent watering. If the annual grows in open soil, it is more drought tolerant, but still requires systematic water treatments.

Fertilizing for timophylla is carried out, starting from the sixth week after planting in a permanent container and spend every 2 weeks with a standard portion of fertilizer for beautiful flowering plants.

The most difficult in the care of timophylla is the constant need for cleaning. Seed formation has a negative effect on further flowering; you can only observe a continuous show for several months if you regularly remove the wilting baskets. The small blossoms of thymophylla are plucked. It is better to make the brushing procedure regular. If the plant did not flower too abundantly and for a short period, shortening the shoots, light pruning (no more than a third of the shoot length), can stimulate flowering again.

Thymophylla outdoors, especially in the garden, often suffers from aphids and powdery mildew. At the first signs of damage, you can try to save the bushes by spraying insecticides and fungicides. If severely affected, it is better to destroy the plants.

Timophylla Propagation

Like most annuals, timophylla is propagated primarily by seed. The plant develops quickly and growing seedlings is quite simple.

Sowing seeds of timophylla is done from the end of February, varying the dates depending on the desired flowering. The last sowings are best limited to mid-April. Sowing in several terms allows to prolong flowering before the arrival of frosts.

For thymophylla use not standard but not too nutritious substrates (an abundance of organic matter often leads to the loss of young plants). Sowing is carried out in shallow pots quite densely, without covering the seeds with soil. Seeds germinate at a temperature of about 20 degrees Celsius in 10-14 days.

Sprouting is carried out after a couple of true leaves, it can be postponed and spend a month after emergence. Timophylla never planted one plant at a time, use small groups or bunches of seedlings in order to get enough dense bushes at once. It is desirable to lower the temperature for young plants to 12-15 degrees of heat, and you'd better start hardening them as soon as possible. Planting in containers and pots can be done as they grow up, but Timophyll can be put out into the fresh air only after the threat of return frosts passes (in the middle zone - not before the end of May). When planting seedlings to neighboring plants, it is necessary to leave a distance of about 20 cm, as bushes expand quite actively.
