Besides, flowers are used as the theme of the events, and colour also matters in sending a particular message.
While others smell soft, others fruity, peachy or even creamy, flowers have their calendars, according to the experts in the flower industry.
"The reds often top the calendar in February, the month of love. The yellows and their shades-like cream, come in during the Easter celebrations, and pink tops during Mothers' Day. The whites peak in June and July during the summertime in Europe when weddings are at the peak. People go for red and white during the Christmas season," said Tirop.
To prepare for Valentine's Day when demand for roses is high, firms start preparations in November.
"Often, once pruned, roses take up to two months to be harvested for export. Part of our preparations to handle large expert shipments to meet customer demands starts early in November. By February, the flowers are mature when they are picked and packaged. By February 7, the last batch of flowers specifically targeted for Valentine's were shipped," said Charles Mulemba, the general manager at the company.
He said by the time the flowers reach other countries, distributions begin from the wholesalers who distribute to retailers and finally reach the consumers on Valentine's Day.
"February is usually the busiest month of the year, and we are often prepared to handle huge demands. The good thing is that it often comes with a bonus when we meet and even exceed our targets," said Ruth Njeri, an employee at the flower farm.
For the local market, bulk buyers often place orders before the day or on D-day.
While the production of flowers is a continuous process, there are flowers targeted for particular seasons and production of the specific colour is often enhanced.
With flowers remaining one of the most loved plants, sustainability in the production of flowers has been key in some flower firms like Sian Roses.
Elizabeth Kimani, a quality assurance officer at the company, said that while Kenya leads the region in floriculture innovations, most production systems are carbon and resource-intensive.
"The current biggest debate is on global warming. With most investments being carbon and resource-intensive, there is a need for the adoption of renewable sources of energy that are sustainable to avoid over-reliance on non-renewable ones," she said.
She added; "Flower industry is one of the most vibrant sectors. Over the years, the industry has taken approaches to ensure sustainability in production. Among the major approaches we have taken is the adoption of solar, use of sea freight to ship flowers among other local approaches."
Raphael Kiptis, a finance officer at the company, said that while electricity bills could run up to Sh 10 million per month within the four flower farms, among them Sian.
He added that the unreliability of the power supply posed a major challenge to running huge investments that required sustainability.

"We shifted to renewable energy so that we could both reduce costs as well as lower our carbon footprints," he said.
