Alcea rosea aka Hollyhock
Taxonomy
Alcea rosea, commonly known as the hollyhock, is an ornamental dicot flowering plant in the family Malvaceae. It was introduced to Europe from southwestern China, possibly before the 15th century. The plant has lobed rounded leaves and produces tall spikes of open funnel-shaped single flowers. These flowers start with bright pink edges that fade to paler pink towards a yellow center during the summer. Hollyhocks are typically short-lived perennials. They are a popular choice in cottage gardens, blooming abundantly in mid-summer. While many varieties are biennials, requiring two years to complete their lifecycle, there are also short-lived perennial varieties that can flower in their first year if planted early or started indoors. Hollyhocks require minimal maintenance, apart from staking and pruning after flowering. However, they are susceptible to insect pests and fungal diseases like rust. In the United States, hollyhocks can be invasive. Overall, Alcea rosea is a charming and versatile plant that adds beauty and color to gardens.

Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Hollyhock will be sure to bring you many years of beauty and enjoyment.
